Why Biotin Supplements Help With Hair Fall

Biotin, or vitamin B7, plays a vital role in keratin production, the protein that forms hair, skin, and nails. Deficiency in biotin can lead to brittle hair, dryness, and increased hair fall. Taking biotin supplements not only helps replenish deficiency but also supports healthy cellular function and scalp nourishment, naturally reducing hair thinning and fall.
