Can You Colour Your Hair After a Nanoplasty Treatment?

Nanoplasty has quickly become one of the most popular smoothing treatments on the market and for good reason. It leaves your hair shiny, smooth, and frizz-free for months, all without the harsh chemicals of traditional straighteners. But one of the most common questions clients ask is:
“Can I colour my hair after Nanoplasty?”

The short answer is yes — but timing is everything.

Understanding What Nanoplasty Does

Nanoplasty works by infusing the hair with amino acids, proteins, and other nourishing ingredients that help realign the hair’s natural structure. Unlike chemical straightening or keratin treatments that rely on strong ingredients or formaldehyde, Nanoplasty smooths the hair by rebuilding the bonds and sealing the cuticle with heat.

This sealing process is what gives the hair its incredible shine and humidity resistance but it also means your hair cuticle is temporarily “locked down.” That’s where timing matters when it comes to colour.

When Can You Colour Your Hair?

It’s best to wait at least 7 to 10 days after a Nanoplasty treatment before applying any hair colour.
Here’s why:

• The treatment needs time to fully stabilise and set in the hair.

• Colour applied too soon may not penetrate evenly, resulting in patchy or faded results.

• Some pigments can also interfere with the treatment’s longevity and shine.

If you’re planning a lightening service (like balayage or foils), it’s better to do it before your Nanoplasty otherwise, the smoothing formula can make it harder for bleach to lift.
If you want to tone or darken the hair, it’s safer to do it after your Nanoplasty, once the hair has settled.

Pro Tip: Protect Your Colour

When colouring post-Nanoplasty, always use sulfate-free and sodium-free shampoo. These gentle formulas help maintain both your new smoothness and your fresh colour for longer.
