Frizz that shows up the second it rains. Morning routines that eat forty minutes with straighteners. If that sounds like your hair, a keratin treatment in Manchester is probably the fix you’ve been circling for a while. The most common question we hear at David Rozman is simple: how long does it actually last?
Honestly, the answer depends on a few things. But most clients get three to five months of smoother, calmer hair from a single visit. Here’s how it works and what stretches that result further.
How a keratin treatment in Manchester actually works
Keratin is a protein your hair is already made of. Over time, heat, colour and daily wear break down the outer cuticle, which is where frizz and dullness creep in. The treatment coats and bonds keratin into the hair shaft, then we seal it with heat.
The process takes roughly two to three hours depending on length and thickness. We wash, apply the formula, dry, then flat-iron in fine sections to lock everything in. You leave with hair that’s smoother straight away. If you want the full breakdown, our guide to keratin smoothing benefits covers the science in more detail.
How long does keratin smoothing last?
Three to five months is the honest range. Fine hair sometimes holds it slightly longer because there’s less bulk to relax. Thick, coarse or heavily coloured hair can sit at the shorter end.
The single biggest factor is aftercare. Sulphate-free shampoo is non-negotiable. Sulphates strip the treatment fast, and we’ve seen results cut in half by the wrong bottle from a supermarket shelf. Brands like Kérastase do sulphate-free ranges built exactly for this. Wash less often, use lukewarm water, and skip tight bobbles for the first few days.
As it fades, it fades gently. There’s no harsh regrowth line like you’d get with colour. The hair just gradually returns to its natural texture, which means no awkward in-between phase. Pair it with a regular keratin smoothing appointment every few months and you keep hair permanently manageable.
Why clients choose our keratin treatment in Manchester
We don’t do one-size-fits-all. Every treatment starts with an assessment of your hair’s condition, porosity and colour history, because a heavily bleached head needs a gentler approach than virgin hair. That care is what makes the result last.
Based near the city centre, we’re an easy walk from most of town and close to Piccadilly station. Loads of clients pair the treatment with a fresh cut and finish so the shape shows off the new smoothness. A tidy ladies’ cut and blow dry on top just makes the whole thing sing.
Expect to pay somewhere between £120 and £250 depending on length and density. It’s an investment, but spread across four or five months it works out cheaper than the daily heat damage you’d otherwise pile on. Our full team of Manchester hairdressers handles these day in, day out.
Frequently Asked Questions
Can I colour my hair after a keratin treatment?
Yes, but timing matters. We recommend colouring before the treatment or waiting at least two weeks after. Doing both in the wrong order can shorten how long the smoothing holds, so we plan the sequence during your consultation.
Will a keratin treatment make my hair dead straight?
Not necessarily. It relaxes frizz and cuts drying time while keeping movement. If you want poker-straight, we can push it further. Most clients prefer smooth with natural body, which is easy to style either way.
How soon can I wash my hair afterwards?
Wait 48 to 72 hours before your first wash, and avoid clips or ponytails in that window. This lets the keratin fully set. After that, switch to a sulphate-free shampoo to protect the result for as long as possible.
