Try looking into any fix for damaged, thin, or flat hair, and you'll likely come across tons of suggestions to add a product with biotin to your hair-care regimen, ideally in the form of a biotin shampoo. "Biotin is important for energy production and known to improve hair health," board-certified NYC dermatologist Debra Jaliman, MD, assistant professor of dermatology at the Icahn School of Medicine at Mount Sinai, previously told POPSUGAR. "Many enzymes need biotin to function properly; biotin also helps keep nails and skin healthy."
Biotin, also known as vitamin B7, is a B complex vitamin known for its abilities to keep your hair, skin, and nails looking strong and healthy, and even though it's an ingredient that can often be found in edible multivitamins, it's also ever present in shampoos meant to strengthen and add volume to the hair. Of course, while these products can help give the hair a boost, it's also worth noting, according to Dr. Jaliman, that taking or using biotin shampoos and hair products won't negate a bad diet, and the key to healthy hair growth also lies in nutrition.
Still, there are loads of biotin shampoos on the market that have received praise for their strengthening and volumizing results. Ahead, we're taking you through a few of our favorites.
