I simply love this shampoo! It has helped me with my oily scalp. When I use this shampoo the hair looks clean on day 2, this wouldn’t happen with any other shampoo out there. It also lasts for such...

FYI I have 2a waves that with a good cut and product can get close to a 3. So I see all the bad reviews on this and it freaks me out. So I try other shampoos and my hair feels like straw. I try...

I got a rash on my scalp from this, so I am not sure which irritating ingredient was the culprit. Every time I used this expensive shampoo, my scalp would itch. I thought it was just a coincidence,...

This is my go-to shampoo. Sometimes, I feel that it doesn’t get my hair clean enough, but will let it sit or massage it in for another minute, and it feels more fully clean. This is the only...

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,...

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.
