Great product
First time I used the n° 3, I didn't have the n° 0 and used a lot of product as I had to apply it on wet hair and couldn't tell where I'd applied it in the first place. With n°0 it's a lot easier as I can use it on dry hair and have a better control over how much product I use. Also, my hair felt a lot smoother when I used n° 3 and n° 0 combined than the time I only used n° 3 on wet hair. Totally recommend x

Zero effect
Neither good not bad - no effect at all. The 6 is amazing, but I've tried the 0 and the 3 together - nothing. Literally nothing

Amazing
This paired with either the No.3 before washes or with the No.6 after washes on damp hair has seriously helped to transform my hair. My bleached hair has never been softer or healthier, I will use olaplex foreverrrrr

A great product and works best with a Olaplex number 3 after. Feels similar to a salon treatment.

Faulty bottle
I bought this thinking it would be easier to use. The first time was ok but the second time, the sprayer won’t work. It presses in and nothing comes out so I had to unscrew the top and used far more product than I should have My hair has felt better. After being severely damaged by hairdressers, it has helped to get my hair back to good health
