This shampoo is amazing, I never write a review but I am that happy with the results of this product I can't keep the happiness to myself as I know the struggle of finding a shampoo for your hair type. So I have a very oily scalp and damaged ends, with slight dandruff. When I say oily scalp, I mean I would wash my hair and a few hour later my scalp would be greasy and it made me feel really down. I've tried soooo many shampoos from bog standard to organic, egg washes, apple cider vinigar etc (you get the picture) you name it I've probably tried it. and nothing has worked until this shampoo. I used the shampoo for the first time today and saw instant results, my scalp is super clean, my hair feels, light, fresh and so soft. 100% reccomend this product if you have the same hair issues as I have. Also just to add I think some of the bad reviews about this product don't do this shampoo justice as I've looked further in to system professional products and they do a shampoo for people with dry scalp , dandruff and damaged hair so I think people are buying the wrong shampoo for their hair type and giving it a bad review. This one is purifying and perfect for oily scalp, slight dandruff and dull lifeless hair.
