FAQs Best Shampoo for Keratin Treated Hair


  1. Why do I need a special shampoo after keratin treatment?
    Regular shampoos with sulphates or harsh cleansers can strip the keratin coating, causing frizz and shortening the results of your treatment.

  2. What should I avoid in shampoo after keratin treatment?
    Avoid sulphates, sodium chloride, and drying alcohols. These ingredients can degrade the keratin and dry out your hair.

  3. How often should I wash my hair after a keratin treatment?
    2–3 times per week is ideal to maintain smoothness and allow the treatment to last longer.

  4. Can I use any sulphate-free shampoo?
    Not all sulphate-free shampoos are suitable — make sure the formula is also sodium chloride-free and labelled as keratin-safe.

  5. What ingredients help maintain keratin-treated hair?
    Look for keratin, argan oil, coconut oil, hydrolysed proteins, and panthenol to support shine, strength, and smoothness.

  6. Will the right shampoo make my treatment last longer?
    Yes, using a proper shampoo helps protect the keratin layer, extending the effects of the treatment for up to 3–4 months.

  7. Can I use dry shampoo between washes?
    Yes, a sulphate- and alcohol-free dry shampoo can help absorb oil and extend the time between washes.

  8. What are the best shampoos for keratin-treated hair?
    Highly rated options include Alfaparf Milano Keratin Therapy Maintenance Shampoo, Pureology Hydrate, Olaplex No.4, GK Hair Moisturizing Shampoo, and Kérastase Discipline Bain Fluidealiste Sulphate-Free.

  9. Can I colour my hair after a keratin treatment?
    Yes, but wait at least two weeks or follow your stylist’s recommendation to avoid interfering with the keratin bond.

  10. Should I use a matching conditioner or mask?
    Absolutely. A keratin-safe conditioner or mask helps nourish and prolong the treatment’s smooth, glossy effect.
