How to Use:

Use as the first step in a two-part at-home system with No.3 Hair Perfector (sold separately) to strengthen and repair all types of damaged hair.

• Apply slowly to dry hair, distributing evenly from root to tip.
• Work No.0 into small sections by squeezing the liquid into the hair to be fully absorbed as you go.
• Hair should be damp, not drenched.
• Let process for 10 minutes.
• Do not rinse.
• For the complete treatment, apply No.3 Hair Perfector over hair with No.0 applied to it, combing through as needed.
• Let process for a minimum of 10 minutes.
• Rinse, shampoo & condition.
• For best results, use No.4 Shampoo & No.5 Conditioner.

Pro Tip:

• Brush or detangle hair before applying No.0 so it can easily be absorbed. For thick, coarse, or long hair, work in small sections to ensure each area is fully saturated.
• No.0 bottle should last 3-6 applications, based on hair length and density.
