Great product, bad pump
I really do love this product combined with No. 3. Although it takes consistent use, I've noticed a big difference in my overly stressed hair. The reason for 4 stars and not 5 is the poor quality of the pump. It's not a sprayer pump, but is a streamer pump. I thought I had a defective pump on the fi...

The application is so difficult
Ideally would be easier to apply. The spray comes out in a jet similar to a cheap water gun, I get more on me and the bathroom walls than on my hair. I try to put it on my hands and rub it on but it runs away. I've wasted more than I've used! Please make it more of a mist spray which would be easier...

Disappointed

Oleplex number 0 caused allergic reaction in the areas on my face where it touched my skin. It left very red and angry looking streaks on my face which I washed out right away and it faded after an hour or so the reason I was afraid to use it again. I used oleplex number 3 along with oleplex shampoo and conditioner which left my hair a lot softer and smoother. I am very disappointed I cannot use this product considering how damaged my hair is and with that would caution other customers to look for possible reaction.
Reconsider if buying

Olaplex has ruined my hair. So much breakage. Dry and brittle after several months of use. I had high hopes but now highly disappointed. Not recommended if you value the length and current condition of your hair.
Decent for 4b/c Afro Hair But Made Me Cough
Verified Reviewer
Reviewed at
So far, my hair looks really good and does not look as frizzy as it was looking prior to using this product. I've only used this along with the system twice. However, I am only giving it 3 stars because both times I have used this product, I started coughing quite a bit. I am going to discontinue using the treatment only because the coughing is concerning for me. The other products did not cause any reaction or coughing for me, just the No. 0 treatment.
Needs a mist spray bottle

Love the product but it should be in a mist spray. It's very difficult to put on without wasting loads/ using way too much

I bought this a month ago to try, and I am so happy that I did! After one use, it made my hair feel silky smooth! I felt like I had been to the salon without leaving the comfort of my own home!
