The Ultimate Liquid Primer to Boost and Maximize Your Hair Repair
Take your structural hair recovery to maximum velocity with the salon-inspired OLAPLEX® No.0 Intensive Bond Building Hair Treatment™. This professional-grade liquid treatment serves as an intensive primer, designed specifically to jump-start deep repair, rebuild weak structural links, and aggressively safeguard overall hair integrity.
Equipped with an easy-to-use precision stream nozzle, No.0 delivers the highest concentration of Patented OLAPLEX Bond Building Technology™ of any product in the entire at-home collection. It acts like an absolute magnet for damaged strands, soaking deep into the internal cuticle to reconnect broken disulfide bonds caused by intense chemical bleaching, salon coloring, extreme thermal heat styling, and daily rough friction.
Why It's An Essential System Step:
Scientifically Proven Results: When paired together as a two-part treatment with OLAPLEX No.3 Hair Perfector, it is clinically shown to provide 68% more repair and 3X stronger hair in just a single use.
Targeted Saturation: The easy-spray needle-nose applicator guarantees quick, effortless distribution right to the most compromised sections of your hair.
Clean and Conscious: Fully vegan, color-safe, cruelty-free, and formulated entirely free of parabens, phthalates, phosphates, and sulfates (SLS & SLES).
Highlighted Ingredients:
Bis-Aminopropyl Diglycol Dimaleate: The legendary, patented single active molecule that works from the inside out to patch and permanently link shattered structural bonds back together.
How to Use (The Two-Part System):
Apply No.0 slowly to completely dry hair, distributing evenly from root to tip. Focus on mid-lengths and ends where damage is most severe.
Work the fluid into small sections by squeezing the liquid to ensure full absorption. Hair should be damp, not dripping, drenched.
Allow the product to process on your hair for 10 minutes. DO NOT RINSE.
Apply a generous amount of OLAPLEX No.3 Hair Perfector directly over the hair with the No.0 still sitting on it. Comb through once to thoroughly blend.
Let the combined treatment process run for an additional minimum of 10 minutes.
Rinse out completely, then follow up with your routine wash using OLAPLEX No.4 Shampoo and No.5 Conditioner for absolute optimal results. Use once a week, or 2 to 3 times a week for severely compromised hair textures.
