What does KERAZUL Keratin Treatment do?
It transforms curly, wavy, or unruly hair into smooth, silky, manageable locks for up to 3 months — without split ends. Application is quick and easy at home, delivering salon-quality results.
How long does the effect last?
Typically up to 3 months, depending on your hair type. Many customers report results lasting up to 6 months. Using KERAZUL AfterCare products helps maintain and extend the smoothing effect.
Can I wash my hair afterwards?
Unlike many treatments, with KERAZUL you can wash your hair right away if you use the AfterCare shampoo and conditioner.
Does it contain formaldehyde?
No. The formula is free of formaldehyde and other harmful chemicals, using only high-quality ingredients that repair and nourish hair.
Why is it more expensive?
KERAZUL is a premium product with professional-grade results. A salon keratin treatment can cost around $300. With KERAZUL, you get the same quality for a fraction of that price.

Important factors when buying a keratin treatment
A keratin treatment can transform frizzy, unmanageable, or damaged hair into silky-smooth, shiny locks that last for months. But the wrong choice can damage your hair. That’s why it’s essential to know what to look for.
- Formaldehyde-free: Protects your hair and health.
- Moisturising & repairing: Should hydrate, reduce split ends, and prevent breakage.
- Long-lasting: Ideally keeps hair smooth and frizz-free for 3–6 months.
- Gentle application: Minimal fumes, no eye irritation, no harsh smell.
- Natural ingredients: Quality oils and proteins like keratin, argan oil, or collagen are key indicators.
- Easy to use: Clear instructions, beginner-friendly application.
By following these criteria, you can choose a treatment that truly delivers professional results at home — without compromising the health of your hair.
