What is a keratin smoothing treatment?

Frizz-free, glossy, easier-to-style hair: what a keratin or 12-week blow-dry treatment does and how to look after it.

If you spend ages fighting frizz, especially in damp Irish weather, a keratin smoothing treatment could change your routine. Here's what to expect.

What it does

A smoothing treatment coats the hair with a keratin-based formula that is sealed in with heat. It smooths the cuticle, reduces frizz and cuts down your drying and styling time. It's sometimes called a 12-week blow-dry because the effect gradually fades over the following weeks.

Who it suits

• Frizzy or unruly hair that's hard to control in humidity.
• Thick hair that takes a long time to blow-dry.
• Anyone who wants a sleeker, shinier finish with less effort.

Aftercare

Follow the aftercare advice you're given on the day, as it varies by product. In general, use sulphate-free shampoo and avoid salt water and chlorine where you can to help the result last.
