Professional hair smoothing treatments.

What is the best hair smoothing treatment in the USA?

QIQI Hair Controller and Nanokeratin System are two of the most effective professional smoothing treatments available in the US. QIQI is a glyoxylic acid-based treatment particularly suited to at-home use — it is formaldehyde-free, available in three formulas matched to different hair types, and delivers results lasting up to 5 months. Nanokeratin System is used heavily in professional salon environments and offers specialised formulas for afro, colour-treated, blonde, and natural hair.

Can I do a professional hair smoothing treatment at home?

Yes. QIQI Hair Controller is designed to be applied at home. It uses the same formula as salon treatments but is formulated and packaged for safe at-home use. You need a hair dryer, a flat iron (450°F), and 2–3 hours. Nanokeratin System products are aimed more at professional salon use.

How much does hair smoothing cost in the US?

US salons charge $200–$500 per hair smoothing treatment session depending on hair length, thickness, and the product used. Buying QIQI Hair Controller directly from Nero Hair and applying at home costs significantly less — each 150g unit provides 3+ treatments. Free US shipping on orders over $175.

How long does a hair smoothing treatment last?

QIQI Hair Controller lasts up to 5 months. Nanokeratin System treatments last 12–16 weeks (3–4 months). In both cases, longevity is heavily influenced by your shampoo — sulfates strip smoothing treatments rapidly. Using a sulfate-free shampoo from your first wash after treatment is the most important factor in how long results last.

What is the difference between QIQI and Nanokeratin?

QIQI Hair Controller is a glyoxylic acid-based smoothing treatment available in three formulas for different hair types — thick/coarse, wavy/curly, and thin/delicate. It is well suited for at-home use and results last up to 5 months. Nanokeratin System offers a wider range of specialized treatments — Refortify (afro/textured), Revive (natural hair), Refine (color-treated), Replenish (blonde/bleached) and more. Nanokeratin is used heavily in professional salons.

Is hair smoothing safe for color-treated hair?

Yes, with the right product. QIQI Thin & Delicate is formulated for fine and color-treated hair. Nanokeratin Refine Smoother is specifically designed for color-treated and chemically processed hair, and is safe on all color services including toners and glosses. Do not apply any smoothing treatment within 4 weeks of bleaching.

Do you ship hair smoothing treatments to the USA?

Yes. Nero Hair ships from the USA with free shipping on orders over $175. All professional smoothing treatments — QIQI Hair Controller and Nanokeratin System — are available to buy online and ship directly to your door anywhere in the continental United States.
