Pretty good

This was pretty good, went through a few bottles of it. Cleaned well and didn’t weigh down my fine hair. I have others I like better but I’d use it again.

Good Shampoo

This shampoo is a good everyday shampoo. I didn’t find anything special about it and you may be able to find a better option if price is an issue.

Works well with mask

I use this shampoo once every four washes followed by the K18 hair mask. Make sure you follow the directions for this and the K18 system to work. My thin, fine blonde hair has less breakage than I’ve had in years. It soft and shiny and less breakage means I retain my hair growth! My hairdresser is shocked at how much my hair has improved

Makes Hair Stronger

I don't color my gray hair, and as I age my hair seems to get finer and limper with more frizz. I have used it as a prep for the k18 leave in repair mask . You only need to use a small amount to get lather. In the summer my scalp is more oily and I noticed on day 2 my hair still looks good. Even if I air dry on day 2 my hair still looks full.

Nice lightweight shampoo

This is a nice lightweight shampoo. I bought it in place of Olaplex after all the bad reviews with Olaplex. It's not reach and creamy, but I think it's because it's better for your hair and less chemical, which I prefer.

So gentle

I’m allergic to many ingredients in cosmetic products. I found this to use with the protein builder and I love it. It feels so gentle, minimal ingredients and it soaps up nicely. I love that Lovelyskin Carrie’s all kinds of brands and offers discounts. I will be ordering this again… Oh and you only need a little bit to wash your hair so it’s going to last a while.

Great Shampoo for color treated hair

I’m a new product junkie who always reads the ingredients prior to purchasing. For the best shampoo to retain color and condition of one’s hair, one needs a true sulfate free product. NOT ALL SULFATE FREE stated products are truly sulfate free. I really like the shine, softness, and manageability that this shampoo offers me in addition to it’s ingredients.

Mixed review

I don’t notice anything markedly different with using this shampoo but I absolutely love the K18 mask so I figured I would try other products that they create. I use it as one of many shampoos just to alternate. Not decided if I will continue after I get through the bottle.

Gentle shampoo

Each month I kept trying a new shampoo and never sticked into one. After getting my hand on this one I would never change it and it’s my fourth bottle .

K18 for the Win!

This is a beautiful product. I have used it as a prep for the k18 leave in repair mask as well as on days I only shampoo and condition. It works great either way. My hair loves k18!

Nice shampoo, not as drying as the detox

I have both shampoos from this brand. I prefer this one, it does not dry my scalp out as much, although I definitely am noticing peeling and large flakes coming off of my scalp when I use this. I’m going to try to couple more times before I return and then decide.

Too early to tell?

I have only used this as prep to the K18 Mask twice, so it is too early to tell. I love the mask, so hope this proves to be a good first step!

Great shampoo!

Great shampoo! I wash my hair daily and this shampoo cleans my hair without stripping it. Hair feels really clean and not weighed down at all. Lots of body in my hair after using this shampoo.

Decent Shampoo

Reference: My hair is of medium thickness, asian. I have been looking for a shampoo that isn't harsh, but also actually washes my hair. Most shampoos these days are all about hydration, leaving me with limp hair. The shampoo lathers well & has a very light scent. Liking it so far.

Really Clean

I use the K18 leave-in conditioner, so I was interested in this shampoo. It really cleans the hair and scalp. The first time, I used too much, as if it were any other shampoo. That did not work so well. But when I used a small amount, it worked great! Do, it' concentrated, wonderful and saves money because literally a dime size amount works for my long hair.

K18 Shampoo

I'm using the shampoo and the repair mask. It smooths out my split ends and makes my hair feel stronger.
