Rain on Deansgate. That’s the enemy. You spend twenty minutes straightening, step outside, and by the time you reach the office it’s a frizzy mess again. Sound familiar? For frizz-prone hair, keratin smoothing is the treatment that actually holds up, and the hairdressers Manchester locals trust at David Rozman have been perfecting it for years.
At David Rozman we don’t just slap on a product and send you out. We assess your hair type, your history, and what you want day to day, then tailor the treatment so the results last. It’s about calmer mornings and less time fighting your own hair.
How keratin smoothing works on frizzy hair
Frizz happens when the outer layer of your hair, the cuticle, lifts and lets moisture in. Curly and coarse hair does this more. Keratin is a protein your hair already contains, so the treatment tops it up and smooths that cuticle down.
We apply the solution section by section, then seal it with heat using a flat iron. The keratin protein bonds into the hair shaft, which is why the smoothing effect survives washing, humidity and that Manchester drizzle. The whole appointment usually runs 90 minutes to two and a half hours depending on length and thickness.
What to expect from keratin smoothing treatments
Results kick in straight away. Your hair feels softer, drops most of its volume-frizz, and dries far faster afterwards. Most clients tell us their morning routine drops from half an hour to under ten minutes.
It’s not permanent. Depending on the formula and your aftercare, keratin smoothing lasts roughly three to five months. We cover the full timeline in our guide on how long keratin treatments last. To keep it going, use a sulphate-free shampoo, something like Redken ranges we stock, and skip over-washing. Pair it with a nourishing keratin service and the smoothness holds longer.
Why choose our hairdressers in Manchester for smoothing
Honestly, the difference is in the assessment. A good keratin result depends on getting the formula strength and heat right for your specific hair. Get it wrong and you either waste money or over-process. We’ve been doing this long enough to read hair properly.
We also pair smoothing with the right finish. A fresh cut and blow dry makes the treatment look its best, and a lot of clients book both together. If your hair’s been through a lot, our advice on repairing over-processed hair is worth a read first. You can see more on the dedicated keratin styling page too. There’s a reason people rate the hairdressers Manchester wide who take the time to do it right.
Frequently Asked Questions
Does keratin smoothing make my hair dead straight?
No. It relaxes frizz and reduces volume rather than poker-straightening. You keep natural movement, just smoother and more manageable. If you want it flatter you can still straighten, but most clients love the softer, low-effort finish it gives day to day.
How soon can I wash my hair after the treatment?
We usually recommend waiting around 48 hours before your first wash, and avoid tying it up tightly in that window. This lets the keratin fully set into the hair. After that, a sulphate-free shampoo keeps everything smooth for months.
Is keratin smoothing suitable for coloured hair?
Yes, and it often improves coloured hair by sealing the cuticle and adding shine. If you’re colouring too, we time both around your keratin appointment. Book a consultation and we’ll plan the order properly.
