Formulated for textured hair
Keratin treatment for afro hair.
Not a generic formula applied to every hair type. Treatments specifically engineered for the bond structure of afro and tightly textured hair. Formaldehyde-free. Results from smoothed texture to fully straight.
The problem
Most keratin treatments are not made for afro hair.
The majority of keratin treatments on the market use a single formula designed around European hair textures. When applied to afro and type 4 hair, these formulas either fail to penetrate the tighter curl pattern effectively or over-process the hair because the chemistry is wrong for the bond structure.
Afro hair has a distinct internal structure — more disulfide bonds, higher porosity, and a flatter cross-section than straight or wavy hair. A keratin treatment formulated for this specific structure delivers dramatically better results with less risk of damage.
That is why Nanokeratin developed Refortify — a smoother engineered from scratch for afro and tightly textured hair. And why QIQI has a dedicated Thick & Coarse formula with higher concentration for resistant hair types.

Common questions
Keratin treatment for afro hair — FAQ
Which keratin treatment is best for afro hair?
Nanokeratin Refortify Smoother is specifically formulated for afro and tightly textured hair. It is the only keratin treatment in the Nanokeratin range designed from the ground up for type 4 hair. QIQI Hair Controller Thick & Coarse is another strong option — it permanently softens resistant hair for up to 5 months.
Can keratin treatments damage afro hair?
Not when you use the right formula. Generic keratin treatments can over-process textured hair because they are formulated for European hair types. Nanokeratin Refortify is engineered for the specific bond structure of afro hair — it strengthens while smoothing, without compromising texture integrity.
Will a keratin treatment straighten my afro hair completely?
That depends on which treatment you choose. QIQI Hair Controller Thick & Coarse can deliver results from loosened texture to fully straight — you control the result with your flat iron technique. Nanokeratin Refortify smooths and reduces frizz while preserving more of your natural texture. Both are formaldehyde-free.
How long does a keratin treatment last on afro hair?
QIQI Hair Controller Thick & Coarse results last up to 5 months — it is a permanent treatment that grows out gradually. Nanokeratin Refortify Smoother lasts 12–16 weeks. In both cases, using sulfate-free aftercare significantly extends longevity.
Can I do a keratin treatment on afro hair at home?
Yes. QIQI Hair Controller is designed for home use — the formaldehyde-free formula means no toxic fumes and no need for salon ventilation. You need a hair dryer, a flat iron that reaches 230°C, and about 2–3 hours. Follow the step-by-step guide included with every order.
What aftercare do I need after a keratin treatment on afro hair?
Sulfate-free shampoo is essential — sulfates strip keratin treatments. For Nanokeratin Refortify, the matched Refortify Shampoo and Mask are specifically formulated for afro hair post-treatment. For QIQI, the Smooth Service Shampoo and Hydration Fixation Conditioner extend results by weeks.
Is keratin treatment safe for 4C hair?
Yes. Both Nanokeratin Refortify and QIQI Thick & Coarse are formaldehyde-free and designed for tightly coiled and resistant hair types including 4A, 4B, and 4C. They strengthen the hair fibre while smoothing — they do not weaken or damage the hair structure.
