5 Best Hair Growth Gummies of 2026, Tried & Tested

Do hair-growth gummies actually work?

Well-formulated gummies can help create the “best conditional environment” for hair growth and health, says Dr. Shamban. However, data is limited, and hair concerns can be complex.

“Hair loss can be from many different factors (autoimmune, hormonal, etc.) that should be evaluated by a dermatologist,” says plastic surgeon Lauren Moy, MD. “Gummies can help if there are small vitamin deficiencies but will usually not provide dramatic results.”

Still, gummies can help ensure you’re getting all the vitamins and minerals essential for hair health. “In that respect, it does help create healthier, stronger, more vital hair as it grows,” says Dr. Shamban.

Genetics and lifestyle factors—like maintaining a nutrient-rich diet and managing stress—also influence hair health, Azadeh Shirazi, MD, FAAD, a board-certified dermatologist, previously told Glamour.

TLDR; Hair loss is subjective and you’ll need to get to the root cause of hair loss to see results, but if you’re looking to simply improve the best environment for hair growth, gummies can help.

What’s better for hair growth, biotin or collagen?

Whether biotin or collagen is better for hair growth is a bit nuanced and can depend on several factors, says Dr. Shamban. “If hair loss is in some way primarily due to a biotin deficiency, obviously a biotin supplementation may be more effective,” she says. However, “if hair loss is related to more structural issues or aging, collagen may be a better option than biotin.” She adds that in some cases, “taking both biotin and collagen together may provide the best results for better hair growth.”

How long does it take hair-growth gummies to work?

“Any supplement would take up to usually between three to six months of consistent usage for any results,” says Dr. Shamban. Buechner adds that hair tends to grow pretty slowly. “About a half inch per month on average,” she says. “Most people need at least two to three months of consistent use to notice less shedding or healthier texture, with more visible changes (like thickness or length) taking closer to three to six months.” And everyone is different, so exact timing will vary from individual to individual, says Dr. Moy. The most important thing is consistency, as Buechner noted—you’re not going to see drastic changes, which can be discouraging, but over time you should notice improvements.

Are there any negative effects of hair-growth gummies?

There are a few disclaimers to consider when it comes to hair-growth gummies. You should consult with a physician before adding any new supplements to your mix. “Too much of certain vitamins (like A, D, E, or selenium) may actually cause hair shedding or other health issues,” says Buechner. High doses of biotin can also interfere with certain lab tests, and you’ll want to be sure your supplement won’t interact with any other medications you may be taking.

Dietary supplements of all kinds are also not regulated by U.S. Food and Drug Administration (FDA), so there’s no guarantee that they contain exactly what they claim, says Dr. Shamban. (Checking to make sure your supplement’s ingredients have been verified by a third-party tester, such as USP or NSF, can help.)

“Plus, [hair-growth gummies] do have a limited shelf life and can degrade without the right stabilisers and fillers, so the potency and impact can lessen over time,” says Dr. Shamban. It’s also important to note that you shouldn’t be taking hair supplements while pregnant or breastfeeding unless otherwise cleared by your physician.
