Nothing special. I have fine, long hair. Nice rice lather, but the smell is nothing to write home about, nothing special about this shampoo (or condition for that matter). Especially for the price...

When this and the No5 conditioner came out, they were hugely lauded as the best s+c duo since the dawn of time and since I was using the No1, 2, and 3 anyway, it seemed logical to me to want to...

I blind bought a 2 litre (!!!) size of this. Such was my faith. I’d already tried Olaplex no.1 and no.2 from its first inception and it was absolutely a game changer. That phrase is used so often,...

I have never, in my life (i'm 40) had a better shampoo. I use it together with the conditioner and my hair looks and feels amazing. I did not get a haircut in more than a year, but the ends look...

This stuff is amazing! I have the whole Olaplex system, but only use the shampoo and conditioner with any real consistency. For reference- I have very thin, curly hair (about 2C curls) to about...

My hair is long, thick, and color treated including balayage. What I look for in a shampoo is something that will lather well and clean my hair without making it feel too dry, stripped, or tangled....

This is nothing special. It is thick so you don’t have to use much, yet it isn’t particularly hydrating and I have never noticed any difference from using it. I won’t be repurchasing.

I can't believe how much this drys out my fine highlighted hair. I like the Olaplex No 3 but so disappointed with 4 and 5. I am not sure if it's the shampoo or conditioner but when I use these...
