• Wait 10 minutes, then apply Olaplex Nº.3 Hair Perfector directly on top of Nº.0. OLAFebSale24
• Comb again to saturate thoroughly, then let the treatment sit for another 10 minutes.
• This treatment is a minimum of 20 minutes, though, just like the Nº.3 on its own, more significant results occur when keeping it on longer!
• Once completed, rinse, shampoo, and condition. We recommend Olaplex Nº.4 Shampoo and No.5 Conditioner.
