Olaplex No.0 Intensive Bond Building Hair Treatment 155ml / 5.2 fl.oz.

Olaplex No.0 Intensive Bond Building Hair Treatment is a professional-inspired pre-treatment designed to prepare hair for deeper repair. Used as the first step in the Olaplex at-home system, it works on all hair types that feel weakened by colouring, heat styling or general wear, helping to support stronger, more resilient-looking strands.

The lightweight liquid formula is applied to dry hair, where it helps to prime each strand so that follow-on products, such as Olaplex No.3 Hair Perfector, can work more effectively. Hair is left feeling smoother and easier to manage, with a healthy-looking shine. Ideal for those who want to care for damaged or compromised hair at home, this treatment fits easily into a weekly routine alongside your usual shampoo and conditioner, offering a focused step that supports the look and feel of hair without weighing it down.

Water (Aqua/Eau), Bis-Aminopropyl Diglycol Dimaleate, Phenoxyethanol, Sodium Benzoate

How to Use:
Start with dry hair. Apply Olaplex No.0 Intensive Bond Building Hair Treatment, working in sections from root to tip until hair is lightly saturated. Leave on for 10 minutes without rinsing, then apply Olaplex No.3 Hair Perfector directly over the treatment and comb through. Leave for at least a further 10 minutes before rinsing, then shampoo and condition as usual.

Frequency:
Use once a week as part of a strengthening routine, or 2–3 times per week on very damaged hair, following the product instructions.

Application Technique:
Apply slowly to dry hair, squeezing the liquid along each section and gently pressing it into the lengths so hair is damp rather than drenched. Layer No.3 Hair Perfector over No.0, ensuring even coverage before rinsing and cleansing.

Best Practices:
For consistent results, use on unstyled, product-free hair where possible. Allow each step its full processing time and follow with a nourishing conditioner. Patch test new products if your scalp is sensitive.

Safety Tips:
Avoid contact with eyes. If irritation occurs, rinse thoroughly and discontinue use. Keep out of reach of children and use externally only. Always follow the directions on the packaging.
