Keratin + Kofein

Bione Cosmetics Keratin + Kofein is a strengthening shampoo aimed at thinning or brittle hair, combining keratin support with caffeine stimulation for the scalp. It lathers into a smooth, rinsing texture that feels balanced—not overly stripping—suitable for regular use. The formula targets resilience and volume while highlighting key actives and potential sensitivities for those with reactive scalps.
