Great
This shampoo leaves my hair and scalp feeling extra clean everytime i use it . Highly recommend it.
Report this reviewGreat for deep cleansing
Great shampoo for deep cleansing hair once per week! Gentle but effective - on my second bottle already!
Report this reviewAmazing
Hair feels so clean after I use this, not stripped has really made a difference and feel like my oils are kept at bay for longer and I can go longer in between washes. Amazing
Report this reviewK18 peptide prep detox shampoo
It didn't work very good for me. Maybe because my hair were already bit dry
Report this reviewNice but a bit pricey
Overall I like the shampoo, it gets the job done (not very hard since I have rather fine hair) and doesn’t dry. The smell is fresh and doesn’t stay. I don’t like the packaging much and I think I will keep looking for something a bit cheaper that does the same.Â
Report this reviewnice detox shampoo
It's a nice clarifying shampoo, probably made to enhance the k18 mask properties. However it's not as strong as the Ouai detox shampoo, so if you are on the hunt of a strong yet not drying clarifying shampoo maybe the Ouai one is a better option. I really like this one but is a bit weak in the cleaning department for me.
Report this reviewJust a perfect clean
Cleans my stubborn scalp perfectly and without irritation. My hair last clean longer. I don't have to use that much product so it will last. I must admit that I wash quite thoroughly my scalp, I mean, I do two washes and massage the shampoo. I don't have to use the scalp scrub that often.
Report this reviewDisappointed
While it's not the worst shampoo I ever tried it certainly didn't live up to my expectations and is very expensive at the same time. I felt like it didn't clean my hair throughly and as a result it was flat and still a tiny bit greasy. Not strong enough to be considered a clarifying shampoo in my opinion.
Report this reviewTerrible packaging
I'm shocked how flimsy the plastic bottle for a shampoo with that pricetag is. Mine came with a chipped cap and spilled all over my order, ruining everything. It smells nice, but since the shampoo bottle is made out of such cheap and flimsy material, I won't repurchase this.
