What is it?

The K Fusion Keratin treatment is the much talked about, less radical alternative to the Brazilian blow dry.

Whilst the Brazilian blow dry, which famously ruined Jennifer Aniston’s hair and forced her to cut it short, uses a combination of formaldehyde and keratin, K Fusion is free from formaldehyde and therefore is much gentler on hair, and is also suitable for pregnant women and those who have undergone chemotherapy.

What does it do?

The treatment aims to smooth frizzy hair, making it feel softer and much more manageable without affecting the natural body of your hair; i.e. if you have curly hair it won’t rid the curls, only the pesky frizz that goes with them.

Sounds GOOD, right? I headed to the London-based luxurious salon Sejour to try it out for myself.

What is the treatment like?

After two shampoos (in a massage chair, HELLO), to ditch remaining products and to open cuticles in your hair for the solution, hair is dried off and put into sections. This is followed by the generous application of the keratin solution, which is left for twenty to forty minutes (depending on the texture of your hair). Since my hair was reasonably smooth to begin with, the treatment was left for around twenty minutes, with the stylist occasionally combing it through to ensure my whole head was covered.

After this, my hair was rinsed out thoroughly, dried on a medium heat and vigorously straightened. The stylist had to ensure each strand of hair was ironed in order to seal the treatment properly and voila! Job done. Although this sounds relatively simple, the various stages of the treatment means that it takes a long time to complete – I was there for around the three-hour mark so be sure to pick up a magazine!

After care

The treatment is supposed to last around three months, but in order to keep the treatment effective for as long as possible you mustn't wash your hair following the treatment for at least 2 days. Following this, it's also essential to only use sulphate-free products which won’t interfere with the solution.

Does it work?

The copious straightening, which is necessary to develop the keratin treatment, made my hair feel a little flat after leaving the salon, and I was worried that the smoothing solution on my already reasonably smooth hair had taken out the body it did have (even though my hair did feel lovely and smooth). However, in the days since the treatment after a couple of washes I have definitely been able to tell a positive difference in my hair, with it being much more manageable after blow drying, easier to style and staying in place after I have curled or straightened it for much longer. My hair even looked decent after being caught out in the rain, which is an achievement in itself!

How much is it?

At Sejour the price depends on hair length and ranges between £150-£250.

Is it worth it?

Although my hair feels better, more manageable and softer, I would suggest this treatment is not that necessary for how much it costs if you already have reasonably smooth hair. However, I would certainly recommend the treatment to anyone who suffers from frizz – it’ll make all the difference and it won’t damage your hair. That’s a win-win!
