Olaplex
Olaplex repairs the bonds in hair that are damaged by color, bleaching, and heat. You choose the number, because each number has its own step in the routine.
Start with No.0 Bond Building as a pre-treatment. For washing and conditioning, choose the No.4 Maintenance Shampoo with the No.5 Maintenance Conditioner. If you have fine hair, there is No.4 Fine and No.5 Fine. For blonde hair, the No.4P Blonde Shampoo is suitable. For extra moisture, there is the No.8 Bond Intense Moisture Mask.
To finish, use the No.7 Bonding Oil or the No.9 Nourishing Hair Serum for shine and less frizz. For curls, there is the No.10 Bond Shaper Curl Defining Gel. No.1 and No.2 are the treatments in the salon. For home use, there is the No.3 Hair Perfector.
Not every number is always in stock; you can see what is immediately available on the product page.
