Using biotin shampoo alone isn’t nearly as effective as having a full-fledged, biotin-rich routine. “Some patients have reported hair growth and stronger hair, along with reduced hair loss, but shampoos as a delivery method for ingredients may not be ideal since they are slathered onto the scalp and hair and rinsed off shortly afterward,” Dr. Tiffany Libby explains. After shampoo and conditioning, Dr. Libby advises using other topical biotin products elsewhere in your routine. Enter: hair serums.
“If there is interest in using topical biotin, I would recommend a leave-on daily treatment, like SpoiledChild A22 Biotin Boost Hair + Scalp Serum, formulated with rosemary oil, caffeine, and niacinamide, and has demonstrated hair growth benefits. It is an elegant, lightweight formulation in an easy-to-use spray that is fast-absorbing and residue-free, and does not weigh hair down while it is working on the scalp,” she explains.
