If I wash my hair immediately after keratin treatment, will it damage my hair?

After a keratin treatment, it’s important to wait before washing your hair. Washing it too soon can interfere with the bonding process, reducing the treatment's effectiveness and shortening how long the results last.

Why you shouldn’t wash your hair immediately

Keratin treatments need time to set into the hair shaft. Washing your hair right away can interrupt this setting phase, leading to:

• Loss of smoothness and shine
• Frizz returning prematurely
• Weakened results that don’t last as long

Professionals typically recommend waiting at least 48 to 72 hours after the treatment before your first wash. This ensures that the keratin has enough time to properly bond with your hair for long-lasting results.

What happens if I wash too soon?

Washing your hair immediately can cause the keratin formula to rinse out before it’s fully absorbed. This can leave you with uneven texture, reduced shine, and frizz. While it won't "damage" your hair in the traditional sense, it will likely reverse many of the benefits of the treatment.

How to wash your hair after the waiting period

• Use sulfate-free shampoo and conditioner. These products help preserve keratin in your hair.
• Stick to lukewarm or cool water to avoid opening the hair cuticle and weakening the effect.
• Be gentle during your wash — avoid rough scrubbing or over-shampooing.
