Hair green L67.8

Green discoloration of the main hair, especially in blonde, grey and bleached hair

External copper adsorption, usually as a result of exposure to copper-containing tap or swimming pool water. Green discoloration of hair after application of copper-containing cosmetic plant extracts has also been described (Tosti A et al. 1991). Physically and chemically stressed hair promotes the absorption of copper on the hair shaft.

In blonde hair, strongly chlorinated water can also lead to a green tint of the hair.

Copper complexation by hair rinse with chelating agents. Treatment trial with 3% hydrogen peroxide or, if necessary, shampoos containing EDTA or 1.5% hydroxyethyldiphosphoric acid. Prophylactic washing with synthetic detergents or shampoos that contain quaternary ammonium compounds and thus prevent adsorption.

In case of green coloration after a visit to the pool, only a suitable hair tint (with low red pigments) can correct the green cast.
