What is a keratin blowout?

Let’s get one thing straight: a keratin blowout isn’t about poker-straight hair. It’s about smoothing things out, calming the fluff, and giving your hair a softer, glossier finish that lasts far longer than your usual blow-dry. The idea is to reduce frizz, not remove every wave or curl.

A keratin blowout works by coating your hair with a special protein-rich formula. Keratin is something your hair already contains — but over time, damage, colouring, and heat styling chip away at those natural proteins. The blowout helps put some of that back in. It’s sealed in using heat, leaving you with hair that’s more manageable, shinier, and far less prone to the dreaded humidity fuzz.

At Salon No. 100, your Solihull hairdresser will walk you through whether this treatment is right for you, based on your hair type and what you’re hoping to achieve.

Who it’s for — and who it’s not

Keratin blowouts are great for anyone dealing with frizz, unruliness, or general puffiness. If your hair gets big when it rains, or it takes forever to smooth out with a round brush, this could be the thing that saves you half an hour in the morning.

But if you’ve got extremely fine hair or a very sensitive scalp, it’s worth checking in with your stylist before booking. Some formulas can be a bit too much for certain hair types, and while most modern keratin treatments are much gentler than older versions, not every head of hair is built the same.

And no — a keratin blowout won’t turn your curly hair stick-straight. It’ll soften your curl pattern and help it sit more evenly, but it’s not a chemical relaxer.

How it works and what to expect

When you come in for a keratin blowout, your stylist will start by washing your hair with a clarifying shampoo. That strips away product build-up and opens the cuticle so the treatment can soak in properly.

The keratin solution is then applied section by section, from roots to ends. Once it’s all in, your hair is blow-dried smooth and then straightened with a flat iron. The heat is what locks the keratin in and gives it staying power.

The whole process can take a couple of hours depending on your hair length and thickness. But once it’s done, the results can last up to twelve weeks with the right care.

Your hairdresser in Solihull will explain how to look after it properly — that includes using sulphate-free shampoo, avoiding salt sprays, and going easy on the swimming.

Will it change how my hair feels?

Absolutely — and in a good way. Most people find their hair feels softer, silkier and far easier to manage. Blow-drying takes less time, and the hair tends to hold its shape better between washes.

It doesn’t weigh your hair down like some heavy treatments. Instead, it smooths without flattening. You’ll still have movement and bounce — just with less fluff.

And if you’ve been battling dry or coarse ends, this treatment can give them a much-needed break. Just make sure you’re using the right aftercare products so the results last.
