Why Your Nanoplasty Didn’t Work (and How to Get It Right)

Nanoplasty has quickly become one of the most requested smoothing treatments for those seeking sleek, frizz-free, and manageable hair — without the harsh chemicals associated with traditional keratin. But what happens when the results don’t match the promise?

If your Nanoplasty didn’t last, left your hair feeling dry or brittle, or didn’t give you that smooth, glossy finish you were hoping for, you’re not alone. Every week at The Cutting Room, we hear from clients who’ve had disappointing experiences elsewhere.

Here’s what we want you to know: when Nanoplasty doesn’t work, it’s rarely because the treatment itself is flawed — it’s almost always due to poor application, incorrect technique, or lack of professional knowledge.

Let’s break down the most common reasons your Nanoplasty didn’t deliver the results you expected — and how to make sure your next treatment gives you the beautiful, long-lasting transformation it should.

1. It Wasn’t Done by a Qualified Hairdresser

Nanoplasty isn’t something that can be mastered in a weekend course. It requires more than just following basic instructions — it demands a strong understanding of hair biology, chemistry, and styling techniques.

We’re seeing more and more people offering Nanoplasty without being licensed hairdressers. Some of them advertise services from home salons, relying on social media testimonials instead of real credentials. While their prices may be tempting, the risks are high — especially when your hair’s health is on the line.

Nanoplasty isn’t just “paint on, flat iron, done.” It takes:

A deep understanding of hair structure and condition
The ability to tailor the treatment to different hair types (curly, coloured, damaged, fine, thick, etc.)
Careful control of heat, timing, and product saturation

In untrained hands, even the best Nanoplasty product can lead to poor results — or worse, hair damage. If your hair felt dry, brittle or broke after your treatment, there’s a good chance the application wasn’t done properly.

At The Cutting Room, our team consists of experienced, professionally trained stylists who have performed over 3,000 Nanoplasty treatments. We assess every strand of your hair — from porosity and density to colour history and heat sensitivity — before even starting the treatment.

If your Nanoplasty was performed by someone without that level of knowledge, it may not have penetrated the hair properly, been sealed correctly, or matched your hair’s specific needs — leading to disappointing (and sometimes damaging) results.

2. The Wrong Heat Setting Was Used

One of the most damaging mistakes we see is the use of excessive heat — particularly flat irons set to 250°C or more. That level of heat can literally burn your hair, especially if it’s fine, coloured, bleached, or chemically processed.

Nanoplasty needs to be sealed with heat, yes — but the temperature must be carefully adjusted based on hair type and condition. Using too much heat can:

Break down essential protein structures in the hair
Cause irreversible damage and breakage
Leave the hair dry, fragile, and prone to snapping

In contrast, using too little heat means the treatment won’t seal properly — which can make it appear as if Nanoplasty “didn’t take” or “washed out.”

Heat control is critical — and only experienced stylists understand how to customise it for best results. More signs of heat damage and incorrect application are covered in our post Signs Your Nanoplasty Was Done Wrong.

3. It Didn’t Last Because It Wasn’t Applied Correctly

Done right, Nanoplasty should last 5 to 7 months — not 5 to 7 weeks. If your hair became frizzy again after only a few washes, it may be because:

The product wasn’t evenly or thoroughly applied
Processing time was too short
Excess product was rinsed out prematurely
The hair wasn’t properly clarified beforehand

Even small missteps in application can affect the end result. At The Cutting Room, we ask clients to arrive with clean, dry hair that has been shampooed 48 hours prior — this allows us to begin treatment on hair that’s free of heavy product buildup, without overstimulating the scalp. We don’t clarify the hair immediately before treatment, as that can lead to unnecessary irritation while Nanoplasty processes.

If a stylist skips this kind of preparation guidance or starts the service on hair that hasn’t been properly prepped, the product may not bond as effectively — leading to shorter-lasting results.

4. You Weren’t Given Proper Aftercare Instructions

One of the most overlooked parts of Nanoplasty is what happens after you leave the salon. Many people assume it’s a “set-and-forget” treatment — but that’s not entirely true.

To preserve your results and avoid premature fading, it’s important to:

Use sulfate-free, silicone-free shampoo and conditioner
Avoid heat styling with no protection
Delay colouring, bleaching, or chemical services for a few weeks post-treatment
Minimise exposure to chlorinated or salt water without proper protection

Sadly, some salons skip this crucial education step, or worse — give incorrect advice that leads to clients unknowingly undoing their results.

5. Your Hair Type Wasn’t Properly Assessed

Every head of hair is unique — and Nanoplasty must be customised accordingly. If your hair was bleached, highlighted, chemically processed, or naturally curly, a stylist needs to evaluate how those factors affect treatment timing, product concentration, and heat use.

For example:

Coloured or bleached hair requires gentler heat and longer processing
Very curly hair may show a “regrowth” look after a few months
Fine or thinning hair needs lighter application and more attention to timing

If your stylist didn’t ask about your hair history, or didn’t tailor the treatment to your needs, it could explain why your results were underwhelming.

6. You Didn’t Know What to Expect (Because No One Told You)

If your stylist promised pin-straight hair with zero effort and no follow-up — that was a red flag. While Nanoplasty delivers fantastic results, it’s important to understand what it can and can’t do:

It will smooth, de-frizz, and soften your hair
It will relax curls — it does not preserve your natural curl pattern
Results are instant and visible on the day
On blonde/lightened hair, it may cause slight tonal shifts (which we know how to minimise)

The takeaway? Set realistic expectations and choose a stylist who’s upfront and honest about the process.
