The professional product — with the tools to use it.
DIY keratin treatment kit
Most "at-home keratin kits" are diluted versions of salon products. The Nero Hair DIY Treatment Kit is built around QIQI Hair Controller — the same professional treatment salons use — plus the heated cap, brush, bowl and gloves you need to apply it properly at home.

The short answer
Everything for a professional treatment, in one box.
The kit contains QIQI Hair Controller in your chosen formula (Thick & Coarse, Wavy & Curly or Thin & Delicate), a professional heated cap, a precision applicator brush, a mixing bowl and gloves.
You will also need a clarifying shampoo, a hairdryer with a round brush and — for the sleekest finish — a flat iron that reaches 230°C. Follow our printable step-by-step guide for your formula.

In the box
What’s inside.
QIQI Hair Controller (your formula)
The professional, formaldehyde-free smoothing treatment. Choose Thick & Coarse, Wavy & Curly or Thin & Delicate.
Heated cap
Professional grade — the heat stage activates the treatment, so this is the tool that makes home results possible.
Applicator brush
Precision tip for applying close to the root and saturating every section.
Mixing bowl
Plastic, as the treatment should not go into a metal bowl.
Gloves
Wear them for the whole application.
How it works
The method, in short.
1. Cleanse
Shampoo twice with a clarifying shampoo, no conditioner. Towel-dry to 90%.
2. Apply
Apply 0.5cm from the scalp through to the ends, saturating every strand. Cover with a plastic cap.
3. Heat
Process under the heated cap on high: 30–90 minutes depending on your hair type and condition.
4. Rinse and finish
Rinse lightly to 90%, then blow-dry — and flat-iron for maximum straightness. No downtime afterwards.

DIY keratin kits — FAQ
Do DIY keratin kits work?
They work when the product is professional-grade and you have the right tools — especially heat to activate the treatment. The Nero Hair DIY Treatment Kit uses QIQI Hair Controller, the same treatment salons use, with a professional heated cap.
What is in the Nero Hair DIY Treatment Kit?
QIQI Hair Controller in your chosen formula, a professional heated cap, an applicator brush, a mixing bowl and gloves. You will also need a clarifying shampoo, a hairdryer and — for the sleekest finish — a flat iron.
How many treatments does the kit do?
Up to 3, depending on your hair length and thickness.
Which formula should I choose?
Thick & Coarse for dense, resistant or afro-textured hair; Wavy & Curly for waves and curls; Thin & Delicate for fine, colour-treated or bleached hair. Our one-minute hair quiz will recommend one.
Is it safe to do keratin at home?
With a formaldehyde-free professional formula and the steps followed properly, yes. Patch test first, strand test coloured hair, keep the product off the scalp, and use a lower iron temperature on very porous blonde or grey hair.
