Meh

Meh. I thought it was the winter that was making my wavy hair flat, straight and frizzy but when I stopped using this shampoo it came back to life. Maybe it’s not for my hair type, I won’t be buying again.

Worse thing that has happened to my hair!!

I've been using this product for over a month now and my hair has been shedding by the handfuls, I wish I was exaggerating!! It's the only thing I have changed in my hair routine. I've never experienced this before not even with cheap shampoos. Horrible!!!

Too expensive

Not as good as Olaplex in my opinion. Instead of buying this, buy the K18 hair oil. That stuff is legit!

A must have for healthy hair!

A lot goes a long way. You do not need a lot of product to wash your hair. My hair is slightly below my shoulders and I use about a nickel size dot (if that). I really like how much this shampoo lathers. I have noticed a big difference is how much nicer my hair has been drying since using this product. All of K-18’s products are great!

Wouldn’t use again

I’m so glad I bought the minis to try this line. I purchased this shampoo and the protective conditioner to go with it. I also purchased the leave in conditioner, hair oil, and peptide prep detox shampoo. I used everything as instructed; didn’t use any conditioner before using leave in hair mask, etc. I did not notice anything other than how much static my hair had. I would never use this again or purchase the full size.

Not working for me

I was very excited to try this, especially after using the OG K18 leave in conditioner. Well, it's not for me. I have very fine, thinning hair and I am almost done with my bottle of both the shampoo and conditioner and I don't think it's doing anything. The smell is nice, and it makes my hair feel good, but I still have quite a bit of breakage and I am losing more hair in the shower than I had before switching to this shampoo and conditioner.

Best Product for Frequently Bleached Hair

Amazing amazing amazing. I lighten my hair every 4-6 weeks and have been since 2012, and I have never tried another product that has actually helped my hair maintain its integrity while keeping my hair platinum. Most products have keratin or bonding ingredients that just make my hair worse! I don’t need the extra protein but something to help keep my hair healthy, and this is finally the product!

Terrible, made my hair fall

It made my hair fall! When I read reviews about hair falling, I thought it was due to hormonal changes, but this shampoo made my hair fall so much.
