The best clarifying shampoo I ever used
I love this shampoo . My hair is curly but unhealthy fragile broken and split ends . So I was worry to use it to make my hair more dry but actualy I don't know how it work . After I use it although it make my hair extremely clean like I never felt befor but still don't make it dry at all .my hair just so clean and I love this feeling . Just do not use it more than one time if you gonna use it with the k18 leave in / or once in month to detox your hair from the harm material from water, product and air

Good
Very good product, noticed a difference after 2 washes. Smells okay . It is grey/black when comes out, I was a little freaked out but it was fine, only a small amount needed as foams up a lot. Only time will tell how good it is long term. May purchase more products in time. It is expensive for a shampoo but worth the money if it does a good job.

Great detox shampoo, took to use with hair growth serum
A very good detox shampoo. I bought it when I started to use a hair growth serum, because you need to cleanse and detox your scalp to make such serums be well absorbed and work. The shampoo does the job, I use it weekly for a month by now, the scalp is cleansing, the serum is working, new baby hair are growing, I’m happy and satisfied. I also bought a “ph maintenance peptide prep” shampoo of this brand for daily use. They did not have it in stock on Amazon, but I was lucky to meet it in Vidal Sassoon hair salon for the same price as Amazon. They use K18 hair treatments in the salon and my hairstylist said their contents are “amazing”.

Quality product
I’ve ordered this a few weeks ago and have been using it about twice a week. I don’t know if it’ll make my hair grow. It’s too soon to tell, however I can see that my hair’s texture has changed. It used to feel weak and brittle, sometimes tough like a broom. I’d have to use so much conditioner to be able to brush it, yet the next day it looked like I haven’t haven’t washed it in days - this was with other shampoos. I have straight, fine hair. And I’m 23. I’ve dyed it about 6 times since I was 15. This is the first shampoo that has given my hair volume, shine and made it feel nice to touch. I recommend being careful when it comes to quantity. Too much will make it tough to touch, it will create frizz and even dandruff. Just enough (for your hair type and length) might give you the same results as me. Thank you.

Not for me! No difference in my hair noticed, and ridiculously priced!
IF YOU ARE BUYING THIS BECAUSE GOOGLE TOLD YOU IT WOULD FADE YOUR TOO DARK, SEMI PERMENANT HAIR DYE, DON'T BOTHER WASTING YOUR MONEY! It didn't tone the hair dye down at all. To be honest, I didn't notice any difference to using it on my hair at all, apart from it drying my hair out. A big waste of money, in my opinion.

My new favorite detoxifying, clarifying shampoo
The fact that this was the first and only detoxifying shampoo that I've ever used, causing it to be my favorite in a one-and-done type of deal, is amazing. Not only does it lather pretty well but I literally can feel my hair and scalp being cleansed, cleaned, and washed healthily, if that makes sense. It probably only takes two to three washes for me to feel like that but sometimes I do a fourth just in case. And with this one, a little does actually go a long way, especially after the initial wash. It does very well on my scalp. I have no adverse reactions and the scent of it is actually pretty decent for me. It's very mild as well. Now I'm not a huge fan of the price of this detoxifying shampoo; however, compared to some other detoxifying shampoos I researched, this one is right up my alley with proven results. The bottle size appears small but there's actually a lot of content in it. In my opinion you get a good value for your money. The color of the shampoo is different from what I'm used to. However, as long as it works, I like it, and it does what it's supposed to do (which is to detox my hair and scalp), I don't care if it looks like the color of the planet Mars. Most definitely a 10/10 recommend.

Parfait pour moi
Ce shampooing a montré son efficacité sur mes cheveux dès le premier lavage. A présent ils sont plus doux et mes boucles sont mieux définies. Évidement il est a coupler avec un bon shampooing traitant votre autre problématique.

Works brilliantly
Works brilliantly.i have used it once and it worked better than I expected. I can see it being quite drying after using it over a week, but it cleans the hair and does remove the build up! My hair looks lighter and brighter and dried extremely fast compared to my usual blowdry time. I have blonde, long, fine, thick hair also.
