Are ammonia free hair colours safe?
Q: Are ammonia free hair colours safe for the hair and skin of the scalp? I have 20 % grey hair. I am 31 years of age female, mother of a 2 year baby girl.
A:It is safer to use vegetable dye based hair colours as the likelihood of allergy and chemical reaction is less, though the potential still remains as compared to ammonia and other chemical-containing dyes.
