If you spend half your morning fighting frizz — or you’ve simply given up and tied it back — you’ve probably wondered whether a keratin smoothing treatment is worth the money. It’s one of the most-asked questions we get at Hairacy in Epping, and the honest answer is: for the right hair, it can be life-changing. Here’s exactly what a keratin treatment does, what it doesn’t do, and how to decide if it’s right for you.
What is a keratin smoothing treatment?
Keratin is the protein your hair is naturally made of. A smoothing treatment infuses a keratin-based formula into the hair and seals it with heat, filling in the roughness along each strand that causes frizz and flyaways. The result is smoother, glossier, more manageable hair that dries straighter, styles faster and stands up to humidity far better than before.
Importantly, keratin smoothing is not a chemical straightener. It doesn’t permanently change your hair’s structure or leave a harsh line. It relaxes frizz and loosens the curl or wave while keeping natural movement — so your hair still looks like your hair, just calmer and shinier.
What to expect during the appointment
The process is straightforward but does take time — usually a couple of hours, depending on your hair’s length and thickness. Your stylist will wash your hair with a clarifying shampoo, apply the smoothing formula, let it develop, then blow-dry and seal it in section by section with a flat iron. There’s no pain and no downtime — you walk out with sleek, shiny hair straight away.
How long does it last?
Most keratin smoothing treatments last around three to five months, gradually washing out rather than growing out with a hard line. How long your results last comes down to your hair type, how often you wash, and — crucially — your aftercare products. Because it fades softly, there’s no awkward regrowth stage, which is one of the reasons people find it so easy to live with.
The aftercare (this part matters)
To get the full life out of your treatment, sulphate-free shampoo is essential — sulphates strip the keratin out faster. We’ll recommend the right products, but the golden rules are simple: use sulphate-free, sodium-chloride-free shampoo and conditioner, avoid heavy build-up, and try not to over-wash. Follow the aftercare and you’ll comfortably reach the longer end of that three-to-five-month window.
Who is keratin smoothing best for?
It’s ideal if you have thick, wavy, curly or coarse hair that frizzes in humidity, or if you simply want to cut your styling time dramatically. Anyone who reaches for the straightener every single morning is a strong candidate — many clients tell us they’ve halved their styling time.
If you have very fine or already-straight hair, the benefit is smaller (though it can still add shine and cut frizz). And if your hair is damaged or over-processed, we may recommend a course of treatments first to get it in the best condition, so the smoothing lasts and looks its best.
So — is it worth it?
For the right hair, yes. When you add up the time saved every morning, the good hair days through humid Sydney summers, the reduced heat styling (which actually protects your hair long-term), and the months of results from a single appointment, most of our clients consider it well worth it. The key is honest expectations and good aftercare — which is exactly what we make sure you leave with.

Frequently Asked Questions
Is keratin smoothing the same as a Brazilian blowout or straightening?
Not quite. It smooths and reduces frizz while keeping movement, rather than permanently straightening. It’s gentler and grows out softly.
How soon can I wash my hair afterwards?
Follow your stylist’s advice for your specific treatment — some let you wash sooner than others. Using the right sulphate-free products from the first wash is what protects your results.
Can I still colour my hair?
Yes. We’ll usually sequence colour and smoothing appropriately — often colour first, then smoothing — so your hair stays healthy. Just let us know your plans at booking.
Will it make my hair pin-straight?
No. It relaxes and smooths while keeping natural body, so curly hair becomes looser and more manageable rather than flat.
