My hair is really light blonde, I mixed a little of this with my regular shampoo to dilute it before washing hair with it,due its color being very strong. no need to leave in for me makes my hair very gray and even a greenish tint in between washes. Is not drying but leaves my hair limp. I prefer my other branded purple shampoo

Posted by Hannah on 18th Sep 2023

I’ve been looking for a purple shampoo that actually works for longer than 3 days and doesn’t dry out my hair. Usually purple shampoo’s make my hair so brittle but the olaplex one changes everything! I tone my hair with this once a week. My hair instantly feels silky upon washing it out and it actually stays this way! My hair is a bit light and fluffy after drying naturally but I have fine hair so that’s expected, and goes away after a few hours. 10/10! Will be repurchasing.

Only issue I have is opening the bottles, the lids are too close to the wide bottle. Great that you only need to use a very small amount too.

I find my scalp gets really dry using the Olaplex No.4P. I easily get dry scalp. It does not lather/foam up as amazingly as the “normal” Olaplex No.4 shampoo does either (shame). But saying that I do think it does tone my blond nicely.

Oh wow! Have been using Kérastase shampoo for blonde hair and thought I'd try this new one from Olaplex and I'm really impressed! Took out more of my brassy ends then the Kérastase was. Will definitely keep using this product!

It is very watery compared to Olaplex regular shampoo and you need a lot more. Your hands turn purple which you are not warned of.
