OLAPLEX Nº.0 Intensive Bond Building Hair Treatment is a concentrated pre-shampoo treatment designed for hair suffering from damage, breakage, and weakness caused by coloring, bleaching, heat, chemical treatments, and daily stress. It helps rebuild disulfide bonds inside the hair structure, strengthen the hair, and prepare it for more intensive repair when used with OLAPLEX Nº.3 treatment.

Its highly concentrated formula is based on OLAPLEX’s patented technology and the active ingredient Bis-Aminopropyl Diglycol Dimaleate, which works to support the reconnection of damaged bonds responsible for hair strength and structure. Nº.0 is used as a pre-shampoo treatment primer, not as a standalone moisturizing treatment, and is mainly designed to enhance the performance of OLAPLEX Nº.3PLUS within a damaged hair repair routine.

How to Use:

1. Use the product on dry hair before shampoo.
2. Section the hair to make it easier to distribute the product evenly from roots to ends.
3. Apply Nº.0 evenly throughout the hair, focusing on lengths, ends, and the most damaged areas.
4. Leave it on for 10 minutes.
5. Do not rinse. Apply OLAPLEX Nº.3PLUS treatment directly over it and distribute or comb it through the hair.
6. Leave Nº.3PLUS on for an additional 10 minutes.
7. Rinse the hair well, then use the suitable shampoo and conditioner.
8. Usually used once weekly or according to the hair’s needs and condition.

Usage Tips from Beauty Time:

• The Beauty Time team recommends using Nº.0 as the first step in the pre-shampoo hair repair routine and not treating it as a leave-in serum.
• To get the function the product was designed for, use it with OLAPLEX Nº.3PLUS instead of relying on it as a standalone treatment.
• Do not rinse Nº.0 after 10 minutes; apply Nº.3 directly over it, then let both treatments work before rinsing.
• Distribute it through the hair in small sections to ensure the product reaches damaged areas evenly.
• Focus especially on ends and bleached, colored, or highly breakage-prone areas.
• The hair does not need to be freshly washed before use, but if there is heavy buildup of oils or styling products, it is better to cleanse it first, then dry it before the treatment session.
• There is no need to leave Nº.0 for longer than 10 minutes before applying the next treatment; more time does not necessarily mean more repair.
• If the hair is severely damaged, focus on consistency in the repair routine instead of increasing the amount of product or leaving it on for hours.
• Do not skip conditioner or a moisturizing mask if your hair is dry; Nº.0 is not a moisturizing treatment.
• For color-treated or bleached hair, it can be included in the routine before and after coloring sessions to help support hair strength.
• If you have had a keratin or smoothing treatment, follow the instructions for the procedure and give the hair the appropriate time gap before introducing additional treatments.
• After washing the hair, reduce high heat and harsh styling to help maintain the integrity of the hair you are working to repair.
