Finding the best hair growth product for you relies on getting to the root of what's causing your hair loss woes. It's important to know that what works for one person might not work for another. That's why consulting a board-certified dermatologist is the best bet for understanding extreme cases or concerns about the cause of hair loss. But if you are ready to choose the right product for your situation, focus on these four factors:
Type of hair loss: Temporary hair loss and thinning can result from illnesses such as COVID-19, according to the American Academy of Dermatology (AAD). Dr. Jake Woods, a board-certified dermatologist, advises that although there isn't an immediate cure for COVID-induced hair loss, there are steps you can take to promote regrowth post-illness. If you notice hair loss three to four months after a mild to severe bout of COVID or the flu, you can almost bet that is the cause. But there are other causes too. "People can also develop hair loss from underlying medical conditions like alopecia areata," Taub says.
Type of hair loss products: Various products are available to address hair loss and thinning, including serums, shampoos, oils, foams, prescription medications and vitamins and supplements. You might find you need a combination of some of the above to fully address your loss.
Key ingredients: Minoxidil and finasteride are commonly prescribed and FDA-approved treatments for genetic hair loss. Dermatologist Michelle Henry says these treatments have demonstrated positive results in stimulating hair regrowth, with individual responses varying.
Budget: Hair growth products can be expensive, so considering your budget is crucial. The good news is, spending more doesn't necessarily guarantee better results. Henry advises focusing on finding the right treatment plan tailored to your specific type of hair loss and individual needs, ensuring a more effective and personalized approach.

To find the best hair growth products, we consulted with top dermatologists, a trichologist and two surgeons for their input on what key ingredients to look for in hair regrowth products. We then researched over 70 hair growth products ranging from vitamins and supplements to serums and oils to shampoos and topical medicated solutions and rated each based on the key ingredients, brand reputation, clinical studies, user results and reviews, among other factors. We then tested quite a few in-house for a first-hand experience.

Results from hair growth products can vary depending on the time it takes to notice them. It's best to address hair loss early — once about half of the hair in a particular area of the scalp is lost, patients tend to notice the problem. Dr. Andy Goren, a clinical dermatologist, trichologist and professor at IMCAS, advises that early diagnosis, such as through a genetic test for androgenetic alopecia, gives the best chance of treating hair loss successfully before it becomes noticeable.

Dr. Jose Diego Mie, a board-certified dermatologist, says lifestyle factors play a prominent role and that maintaining a healthy diet rich in fruits, vegetables, and proteins, staying hydrated and managing stress through exercise, meditation or hobbies can support hair health and growth.
If you have a health condition or are taking medication, it's best to check with your doctor before using hair growth products since some ingredients make them unsafe to use. It's also important to avoid products with finasteride if you are pregnant or planning to become pregnant since exposure can cause birth defects.
Hair growth products are generally considered safe to use. However, if you have an underlying health condition, it's a good idea to check in with your doctor to make sure. (Ditto if you're taking any medications.) Keep in mind that products that contain finasteride are not safe during pregnancy, so women who are pregnant or considering getting pregnant should take a pass on these.

Harassed in Med School
Medical school is a fast-paced, high-pressure environment where students are expected to excel. As part of their training, they learn to navigate tense interactions with faculty, residents, peers, and patients. But what happens when those interactions cross a line and students feel harassed, mistreated, or humiliated? Nearly 40% of medical students reported experiencing harassment during med school, according to the Association of American Medical Colleges' (AAMC's) most recent survey of 2023-2024 graduates. The behaviors include being publicly humiliated or subjected to sexist, racist, or ethnically offensive remarks or names. In addition, almost 40% of graduates reported being publicly embarrassed. Clinical rotation faculty were cited as perpetrators of most of the negative behaviors in the survey. As the AAMC questionnaire shows, mistreatment continues to take place in medical schools despite policies that seek to curb it. Caroline Beit was 4 months pregnant when she entered the Johns Hopkins School of Medicine, Baltimore, in the fall of 2024. From her first day until she gave birth to her daughter earlier this year, she claims she was verbally harassed by faculty and students about her choice to have a baby while attending medical school. She said that one professor told her class that pregnancy was a 'truly horrible disease.' Another initially referred to pregnancy as a 'disease state' before telling the class that their classmate could tell them all about pregnancy. 'The attention on my pregnancy from the entire class embarrassed me,' Beit told Medscape Medical News . In addition, Beit said she felt harassed by students, who asked if they could watch the birth. They commented on her changing body, inquired whether it was a planned pregnancy, and even suggested she have an abortion. She also said that fellow students told her that she should take an exam elsewhere in case she went into labor and distracted them. In response to Medscape Medical News' inquiries about the complaint, a Johns Hopkins University spokesperson said that the school protects student privacy under federal law and could not comment on individual cases or complaints. 'We have long-established policies in place that strictly prohibit discrimination and harassment,' read an emailed statement from a university spokesperson . 'We take all reports seriously and evaluate each one to take appropriate action. If any member of our community experiences or witnesses such behavior, we encourage them to contact the Office of Institutional Equity [OIE],' the statement read. 'The School of Medicine has additional resources to respond to student concerns and address a wide range of potential issues, and we are continually working to ensure that all of our students are treated with fairness and respect.' About Medscape Data Medscape continually surveys physicians and other medical professionals about key practice challenges and current issues, creating high-impact analyses. For example, a soon-to-be-published report on medical school stressors found that One quarter of fourth-year med students have been harassed or bullied by attendings or residents. 19% of med students reported bullying by fellow students. In addition, nearly 30% of students reported unwanted advances from patients, followed by such advances from peers. Among female students, the rate of unwanted advances from patients, 38%, was slightly higher, according to another Medscape report. Filing a Complaint Nathalie Feldman, MD, director of the Learning Environment at The Robert Larner, MD, College of Medicine at the University of Vermont (UVM), Burlington, Vermont, encourages students who believe they've been mistreated to file a report. She said that the bar is very low for reporting at their institution, so they will address anything that makes students feel uncomfortable. She also added that students have a QR barcode on the back of their name badges connecting them with forms to report concerns or unprofessional behavior. 'We try to decrease as many barriers to reporting as possible,' said Feldman, an associate professor in the medical school's Department of Obstetrics, Gynecology, and Reproductive Sciences. Beit said that she filed informal complaints with Johns Hopkins' Office of Medical Student Affairs and formal complaints with the Mistreatment Incident and Learning Environment Surveillance (MILES) Committee, which promotes a safe and respectful learning environment for medical students. MILES must notify and file a complaint with the OIE, which oversees compliance with antidiscrimination and harassment policies. Beit added that MILES also changed her to a different professor's group. In response to the complaints, one professor sent a written apology to her group that he had erred and that 'it was wrong to classify pregnancy as a disease.' She doesn't believe the other complaint was resolved, nor that her complaints led to any significant institutional changes. She didn't file complaints against her fellow students. Why Misbehavior Occurs in Med School Beit is not alone in her claims of mistreatment in medical school. Among the findings of the AAMC's 2024 graduation questionnaire, about 20% of students reported being publicly humiliated, 13% subjected to offensive sexual remarks or names, and nearly 9% experiencing racially or ethnically offensive comments. The statistics have improved slightly since 2020, with more students knowing how to report mistreatment at their schools and reporting it, according to the survey. While most medical educators and staff are 'professional and well-meaning,' some abuse their power, said Tim Lacy, senior director of Student Learning Environment at the University of Illinois College of Medicine, Chicago. 'Some people with poor intentions are opportunistic, taking advantage of sincere or naïve medical students.' Feldman believes that some contributing factors to mistreatment, harassment, or public humiliation of medical students might relate to the hierarchal system of teaching hospitals and to generational differences in communication styles between students and faculty or other supervising clinicians that can cause tension, especially in the 'high-stakes, high-acuity' environment of patient care. Feldman added that often the harassing or bullying behavior isn't intentional but rather committed by individuals who were taught with those same public humiliation techniques and may be unfamiliar with how language and training have evolved. Halting Harassment The Liaison Committee on Medical Education (LCME), an accrediting body for educational programs at schools of medicine, requires medical schools to set standards for student mistreatment, among other qualifications for accreditation. Medical schools are expected to develop written policies that define mistreatment, have mechanisms in place for prompt responses to complaints, and support educational activities that prevent mistreatment, according to the current LCME standards. The LCME standards include general guidelines for creating respectful learning environments and relationships, but ultimately, schools have flexibility in how they apply the principles, so policies differ by school, said Geoffrey Young, AAMC senior director for the Transforming the Health Care Workforce unit. For instance, the University of Illinois College of Medicine has a code of professional conduct for teacher-student relationships and standards for reporting student mistreatment in its Positive Learning Environment Policy. Per the policy, 'Publicly humiliating, physically harming, exploiting, and/or subjecting an individual to unwanted sexual advances are all examples of mistreatment.' Schools must also ensure students understand how to report mistreatment and that 'any violations can be registered and investigated without fear of retaliation.' Among the reasons graduates do not report such incidents are a belief that the school will not act and fear of reprisal. 'Even though there's a policy and a reporting process, we still know there's underreporting because of fear of retribution and retaliation. It's my job to make sure students feel confident and reassure them by reporting and representing their best interests,' Lacy said. He advises students that filing a complaint might affect their career options. If they want to proceed, he cautions students to file reports well before grades are released so the complaint doesn't appear to result from grading. Some students may even delay complaints until after they graduate to avoid repercussions, Lacy said. Beit admitted that she was afraid of repercussions and still is. 'I worry that, given that I have 3 years left, that I will continue to be harassed for having a child while in medical school.' When a student comes to Lacy with concerns, he clarifies whether they want to consult with him confidentially or report an issue. He told Medscape Medical News that most students want a sounding board. The conversation may occur in person, through video conferencing, or via email. Lacy said he tries to respond to the initial report within a day or two, but a complete institutional response to the situation can vary from a day to several weeks. Most of the reports of abuse are from third-year medical students, he added. 'As the year progresses, they come to realize a range of normal clinical behaviors and begin to be comfortable reporting events outside of that range.' In some cases, the school can resolve the situation without reporting an incident. Lacy cited a recent student complaint he received through email, prompting him to speak with the education dean and clerkship director to resolve the issue. 'I consult with whoever has the power to change the situation.' Feldman explained that the tiered resolution process at The Robert Larner, MD, College of Medicine at the UVM starts with an informal dialogue and, if necessary, escalates to a formal investigation. Faculty members may be removed from teaching activities until they complete coaching or a remediation program. If that doesn't prevent recurrence, the incident might be documented in their professional record, leading to other more severe disciplinary actions, such as decreased responsibilities or losing their job. However, Feldman said, 'That's extremely rare, but it's possible.' At the University of Colorado School of Medicine, Aurora, Colorado, several policies and processes help protect students from unprofessional behavior, including a Teacher-Learner Agreement and a Mistreatment Policy. The latter refers students who witness such behavior to the Office of Faculty Relations, which can provide support and help them report incidents. The office directs students whose concerns involve discrimination, sexual misconduct, or harassment to the CU Office of Equity. 'We will talk the student through the process and let them know what to expect,' said Abigail Lara, MD, assistant dean for faculty relations. Resolution procedures run the gamut from potential sanctions against staff who violate the policy — a warning, a written letter of reprimand, or the employee's firing. Other sanctions may include mandatory training, demotion, change in job responsibilities, reduced salary, ineligibility for merit increases, or denying access to all or a portion of the university's property. Protecting Students Two years ago, the University of Colorado School of Medicine launched an antimistreatment effort that analyzed their students' reports of negative behaviors on the AAMC graduation questionnaire surveys from 2019 to 2023. The school conducted its own survey at the end of the clinical rotation period and held focus groups with students, Lara added. She said the campaign decreased experiences of bullying and mistreatment. In addition, if a student reports mistreatment on the survey, it automatically flags an administrator to reach out to the student to see if they want to discuss the issue further. UVM's medical school saw a 'dramatic decrease' in student mistreatment reports from the operating room (OR) when students were better trained to maintain a sterile field, a concern of OR nurses, Feldman said. 'New students were coming into the operating room, and the nurses would bark at them if they got too close to the table. Students reported it as mistreatment to us. So, we created a shadowing [opportunity] where students could follow a patient care associate to learn how to keep a sterile field,' she said. 'Then we went back to the perioperative staff, the nurses where the mistreatment was coming from, and they said the students were so much better prepared. We involved them in training our students, and they were empowered to then teach them the right way to keep a sterile field.' Feldman added that involving the students in the resolution process also can help ease tension. They can also refer students to counseling and psychiatry services to help them cope with the aftermath of an incident. Despite policies and methods for resolving conflicts, Beit believes med schools like hers that value diversity of experiences in their incoming classes should better protect those who don't fit the mold of the traditional student. 'Policies technically prevent discrimination and harassment. In practice, they are not doing enough to protect students,' she said. She understands the risks she took bringing attention to a perceived injustice. But she didn't think the school culture would change unless she spoke up. If medical students feel they've been bullied or harassed, Lacy recommends: Keep a recurring journal or send an email to yourself with the details of an incident. Take notes while you can remember the conversations and specifics, especially if you're considering action in the future. Document the incident with evidence, such as screenshots of chats, in case they are deleted later. If you're unsure about reporting an incident, find a trusted staff member, faculty member, or student leader to consult. Report incidents sooner rather than later so concerns are taken seriously and can be investigated timely.

Shoppers Say This Doctor-Approved Drink Mix from Costco Gives Them More Energy and Glowy Skin
Shoppers Say This Doctor-Approved Drink Mix from Costco Gives Them More Energy and Glowy Skin originally appeared on Parade. Wellness fans, take note: A cult-favorite greens powder that's earned the stamp of approval from health experts is now available at Costco and shoppers are calling it a game changer for energy, digestion and even glowing skin. This drink mix earned top marks from experts at Forbes, WIRED, Women's Health and more. We're listening! AG1 by Athletic Greens, a highly popular all-in-one greens supplement, is now stocked at Costco stores nationwide. Shoppers can pick up a 40-pack box of travel-friendly sachets for $72.99, a rare deal compared to the higher prices found elsewhere. 🍳 SIGN UP to get delicious recipes, handy kitchen hacks & fun food news in our daily Pop Kitchen newsletter 🍳 Touted as a nutrient-dense blend of 75 vitamins, minerals, probiotics and whole-food-sourced ingredients, AG1 is designed to help fill nutritional gaps and support overall wellness, especially for busy people who want a convenient morning routine. The brand recommends taking it first thing in the morning to support energy, gut health and immunity. Costco shopper @costco_empties shows off the popular drink mix in their warehouse: Shoppers say the benefits are noticeable. 'I feel more energized and way less bloated,' one Costco customer wrote. Others rave about improved digestion and skin that feels clearer and more hydrated after a few weeks of use. Some doctors and wellness experts, including neuroscientist Dr. Andrew Huberman, have endorsed AG1 as a convenient nutritional supplement. It's praised for its inclusion of B vitamins, Rhodiola, probiotics and zinc, all of which may contribute to better energy levels, immune support and gut experts also urge caution. Nutritionists stress that AG1 is not a replacement for a balanced diet. It's missing key nutrients like vitamin D3, K2 and iron, and some ingredients—particularly adaptogens—don't have strong scientific backing for the benefits they claim. Additionally, some users report mild digestive discomfort (like gas or bloating), especially when starting out. Another consideration is the price. Even at Costco's discounted rate, it's still one of the pricier greens powders on the market. If you focus on maintaining a healthy diet filled with high-quality nutrients and vitamins, you may see similar results. Health professionals recommend treating AG1 as a supplement to a healthy lifestyle, not a shortcut. 'It's a convenient option, but it shouldn't take the place of fruits, vegetables and whole foods,' says one registered dietitian. Still, for those looking to jumpstart a wellness routine or streamline their morning rituals, Costco's deal on AG1 might be worth a try—especially if you're already a fan of functional wellness drinks and want to see what the buzz is Say This Doctor-Approved Drink Mix from Costco Gives Them More Energy and Glowy Skin first appeared on Parade on Jul 17, 2025 This story was originally reported by Parade on Jul 17, 2025, where it first appeared.

You only need 2 dumbbells and 6 moves to build full-body muscle and boost your metabolism
When you buy through links on our articles, Future and its syndication partners may earn a commission. You're busy — there's work to do, chores to finish, social events to attend and families to look after. That's why you're looking for a short but very effective routine you can do at home to build muscle all over and raise your heart rate with just a set of dumbbells. So, grab a set of the best adjustable dumbbells (these are expensive, but flexible and make a great home workout companion) and roll out a yoga mat, then you're ready to take on this session from YouTube fitness duo Juice & Toya. There are just six exercises in total. You'll repeat the round three times, adding more weight into the mix each time The first round, it's body weight only. Then, one dumbbell, before ending the third round with two weights. If you're not sure which load to lift initially, Toya uses 5 and 10lbs dumbbells for the routine, while Juice works out with 10 and 15lbs. You'll train for 25 seconds, take a 15-second break, then start the next exercise. As there's not a long break between move (15 seconds), adjustable 'bells mean you can quickly switch loads before the next one begins, and you can gradually increase the weight as you get stronger over time, in line with the progressive overload technique. Watch Juice & Toya's 30-minute dumbbell workout I always love Juice & Toya's workouts because they're effective, easy to follow and the pair demonstration different versions of the same move (standard and with modifications). However, for this one, there are no modifications. Instead, as Toya explains at the start, if you need to adjust the intensity of the exercise, either lower the load you're lifting or switch to using your body weight alone. There's a common myth that dropping weights is a 'failure', but it definitely isn't. As someone that's trained with weights for years, the worst mistake I made when first starting out was to lift too heavy. This meant I arched my lower back (hello, back pain) and I didn't focus on my form enough, so I wasn't getting much from the moves either. So, don't do what I did; if you need to drop the weight that's absolutely okay. You want to stick to the correct form to get the muscle-building effects of the routine. Plus, as it's arranged as a high-intensity resistance training workout, there are other benefits too. Working your muscles hard in quick bursts and keep breaks to a minimum increases your heart rate, so you burn more energy than during an equivalent steady-paced routine. And, over time, this can increase your metabolism as well. So, you end up with a muscle-building, core-strengthening, fat-burning, metabolism-boosting workout you can do in less time than it takes to watch an episode of your favorite TV show — and you only need two dumbbells to get started.
