Olaplex - Set Shampoo No. 4 en Conditioner No. 5

First of all, it is best to undergo steps 1 and 2 in a salon. Then use step 3 and then apply the shampoo and conditioner to your hair. Then rinse and continue with steps 6 and 7: the Olaplex leave-in cream and the Olaplex hair oil. Your hair will feel healthy and look shiny again. Olaplex products restore the sulfur bonds that have been broken by, for example, chemical treatments. Products such as bleach and peroxide damage the hair, making it more fragile and prone to damage and breakage.
