After using OLAPLEX No 4 shampoo regularly, my hair feels stronger and less frizzy. The shine has improved noticeably, especially after washing. I use it after applying the No. 3 Hair Perfector and follow with the No. 5 conditioner. My hair is more manageable and holds its shape better.

This shampoo really makes a difference for my dry, damaged hair. It doesn’t leave my hair feeling heavy or dull. I’ve used it for a few weeks now and my hair looks healthier and more resilient.
Olivia Bond –
I noticed better moisture retention after switching to this shampoo. It works well with the No. 3 and No. 5 products in the routine. A little more conditioning is needed for very dry hair, but overall it’s effective.
