I've tested this and it appears that it is not bad. the positives are its pleasant smell and its abundant foam from the first shampoo that makes only 1 shampoo is enough, and therefore despite its price, it is rather economical. the other big advantage is that it is very gentle on the scalp, personally mine is more than sensitive and yet no itching the next day. it outperforms the majority of contractors more expensive shampoo sold in pharmacies. Finally, it leaves a pleasant smell that follows you even the next day. by cons, I do not see that as soon feeling soft, I think it leaves indémêlable hair and therefore the use of a shampoo or miracle after care is essential.
