This shampoo washes just fine oily hair mask! Suffice it to a few drops, and the first time all washed off. Never seen! Very good foaming. So, if you like to strengthen your hair different oils, highly recommend this shampoo! It smells of mint (composed of peppermint essential oil there), but the hair after washing is not felt. Still part of tea tree oil, which has a beneficial effect on the scalp, removes dandruff, itching and irritation of all, normalizes the sebaceous glands.
