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