Permanent solution
Stop managing frizz. Eliminate it.
A professional keratin treatment restructures the hair shaft from the inside — making it permanently resistant to humidity and frizz. Results last up to 5 months. This is what your hairdresser uses, available to buy and apply at home.
Why it happens
Why your hair is frizzy.
Frizz is not a surface problem — it is structural. The hair shaft is made up of disulfide bonds that determine how straight or curly it sits. When the cuticle is open, moisture from the air enters the shaft and causes the hair to swell unevenly. The result is frizz.
Anti-frizz serums and oils sit on the surface and temporarily close the cuticle. They work for a few hours. A keratin treatment works differently — it enters the hair shaft, softens the disulfide bonds, and with heat, resets them into a smoother, straighter configuration. The cuticle is then sealed shut from the inside.
That is why keratin treatments last months and serums last hours. The mechanism is fundamentally different.

Matched to your hair type
Which frizzy hair treatment is right for you?

Make it last
How to keep frizz away for 5 months.
A keratin treatment makes the hair structurally resistant to frizz. Sulphate shampoos actively strip that structure out every time you wash. Most people who say keratin treatments "didn't work" were using the wrong shampoo.
Switch to a sulphate-free shampoo from your first wash after treatment. This single change extends your results from 4–6 weeks to 4–5 months. Everything else — conditioner, oils, styling — matters far less.
QIQI Smooth Service Shampoo is a sulphate-free formula designed specifically for post-treatment hair. It cleans the hair without breaking down the keratin structure.
Questions
Frizzy hair treatment FAQ
What is the most effective permanent frizzy hair treatment?
A keratin or cysteine smoothing treatment is the most effective permanent solution for frizzy hair. It works by restructuring the disulfide bonds in the hair shaft that control curl and frizz — not coating the surface, but changing the structure of the hair. QIQI Hair Controller is a professional-grade cysteine treatment used by UK salons. Results last up to 5 months.
Can I do a frizzy hair treatment at home?
Yes. QIQI Hair Controller is designed for at-home use. You need a hair dryer, a flat iron that reaches 230°C, and about 2–3 hours. The process follows the same steps a hairdresser uses. Most people achieve salon-level results on the first application.
How long does a keratin frizzy hair treatment last?
Up to 5 months with correct aftercare. The single biggest factor is your shampoo — sulphates strip keratin treatments quickly. Switch to a sulphate-free shampoo from your first wash and results will last the full 4–5 months instead of fading in 4–6 weeks.
What is the difference between a keratin treatment and a Brazilian blowout?
Both are smoothing treatments that use heat and a chemical formula to reduce frizz. Brazilian blowout is a brand name — most use similar chemistry (cysteine or glyoxylic acid). QIQI Hair Controller is a cysteine-based treatment, making it formaldehyde-free and safe for home use. The results and process are comparable.
Will a frizzy hair treatment damage my hair?
A quality cysteine or keratin treatment does not damage hair — it adds protein and seals the cuticle. QIQI Hair Controller is formaldehyde-free. The risks come from incorrect application (using the wrong formula for your hair type, applying to recently bleached hair, or flat-ironing incorrectly). Follow the application guide and do a strand test first.
Which formula is right for my frizzy hair?
Thick & Coarse is for afro-textured, coarse, or very frizzy hair. Wavy & Curly is for naturally wavy or curly hair — it reduces volume and frizz while keeping some movement. Thin & Delicate is for fine, colour-treated, or bleached hair. The quiz on this site takes 60 seconds and recommends the right one.
How much does a frizzy hair treatment cost?
A QIQI Hair Controller is £115 for 150g — enough for 3 full treatments, which works out to about £38 per treatment. UK salons charge £180–£340 to apply the same product. The at-home cost over 12 months is a fraction of the salon price.
Can I use a frizzy hair treatment on colour-treated hair?
Yes, with the right formula. The Thin & Delicate formula is specifically designed for fine and colour-treated hair. Do not apply within 4 weeks of bleaching. For hair that has been tinted or highlighted (not bleached), Thin & Delicate is safe to use.
