My hair is quite long and strong. So you need a sensible shampoo. That's what I have found. It has a mild foam that well distributed, and to forward any oodles to shampooing the hair and scalp. The hair squeak clean after rinsing - I am happy! =)
Even the combing turns out no more difficult than with conventional shampoos.
An all around great product for allergy sufferers and people who value fragrance-free cosmetics.
