Olaplex number 4

4 stars out of a maximum of 5

Have been using this product for some time now. I use two-three times a week. It doesn’t really smell of anything or having a lasting fragrance but it has certainly strengthened by hair since using. Like with all olaplex products, a little does go a long way and less is more!

Great results

This may seem expensive for shampoo but it is worth every penny and lasts longer than you will imagine as u need very little. My hair is silky soft, shines and easy to style after using this shampoo

Olaplex

5 stars out of a maximum of 5

Yet another firm favourite from Olaplex. Use it before No.5 to really nourish your hair, and help resurface the texture. Much welcomed hair therapy!

Repeat purchase

5 stars out of a maximum of 5

Always have this in my bathroom. I’ve been using it for years and I use it once a week to keep my hair in good condition. I use several others Olaplex products too as the quality is outstanding. I appreciate that this is expensive but I only need to use a small amount as it lathers well so a bottle lasts several months
