Vitamin B5 (Pantothenic Acid)
A hair-strengthening vitamin that reduces beard breakage and supports thicker, shinier growth.
Vitamin B5 (pantothenic acid) is essential for hair structure. Topical application — usually via panthenol, its precursor — measurably strengthens the hair shaft and adds shine within 2–4 weeks of consistent use. In beard conditioner and premium shampoo, B5 is one of the few actives with clinical hair-benefit evidence.
