Rossmann's shampoo for grey hair popular with women over 40 — what makes it work?

Grey hair appears when melanocytes in hair follicles stop producing melanin, the pigment responsible for hair colour — a process no cosmetic can reverse. However, specially formulated shampoos can improve the condition and appearance of grey strands. A shampoo for mature hair available at Rossmann combines deep cleansing with care and has become popular among women over 40.
