Olaplex: The ‘Best Hair Treatment In The World’ Has Major Discounts In The January Sales

We review Olaplex and investigate Olaplex treatments you can try at home

Olaplex treatment review

by Daniela Morosini |
Updated on

When I heard about Olaplex treatment for the first time a few years ago, a magical new treatment that was hitting the UK from the States that could give me the silky, strong hair of my dreams, I knew I had to try it.

I can spend an entire day idly picking at my split ends. It can frizz up at the mention of rain. It’s sautéed, basically. Coming from Neapolitan stock, I was never going to have the kind of beachy blonde tresses I wanted. Fast-forward through years of straightening, tousling and highlighting, my hair is not really in the best nick it could be. It’s not exactly fried, but it’s also not swishing about like I want it to.

What is Olaplex?

If you’ve had plenty of deep-conditioning, hydrating, glossing treatments over the years but found them to be ultimately disappointing, don’t worry - Olaplex is different. Unlike traditional salon treatments, it works to mend the structure of the hair, rather than smothering it in moisture to mask the damage. Olaplex works to repair broken bonds with their ingredients.

Who uses Olaplex?

Fans include superstar colourist Tracey Cunningham (who works on the manes of Gwyneth Paltrow and Jennifer Lopez, to name a few) who’s so evangelical about the treatment, she went door-to-door flogging it to salons. Plus, the queen of glam Kim Kardashian said it 'really worked' for her hair.

How does Olaplex work?

If you want to get technical about it, colouring splits the sulphur bonds in your hair and eats away at your hair's protein reserves. Olaplex links these sulphur bonds back together, stopping further damage, helping your hair to retain its own proteins and making hair smoother, shinier and stronger.

Your hairdresser will mix Olaplex in with your usual colour dye, which is then applied as normal, before following up with a deep conditioning treatment. Can it fix your heat fried hair? The evidence would suggest so – the before and after pictures speak for themselves...

Impressive, right? In fact, we've only ever heard positive reviews of Olaplex treatments.

What are the benefits of Olaplex?

First things first, if your long hair suffers from splits and breakage, Olaplex is your new hero treatment. As we've mentioned, it works by knitting the bonds in your hair back together, meaning that after one treatment, your frazzled ends will be looking a lot healthier (team this with a quick trim for maximum effect). Your hair will also feel softer, shinier and easier to manage (which can only be a good thing, no?)

Can Olaplex be used on dark hair?

It’s certainly not exclusively reserved for bottle blondes. In fact, Olaplex is ideal as an add-on if you’re a brunette who lifts her colour chemically, as it allows dark hair to be lightened quicker and less aggressively.

Can Olaplex be used alone without colour treatments?

It’s also available as a stand alone treatment, for when your damaged hair is in need of some serious deep conditioning. That's what I did.

What does Olaplex look like before and after?

Nadia at John Frieda doused my hair in the Bond Multiplier, and left it five minutes. She then sprayed in the Bond Perfector for ten minutes, before washing it out. That’s it. That’s all it takes.

Nadia blow dried my hair as normal, and I was dumbfounded. Never has my bottle-blonde hair looked so shiny or felt so soft - without feeling greasy. It swooshed. It bounced. You can see some Olaplex before and after photos here:

How long does Olaplex last?

As Nadia reminded me, Olaplex doesn’t wash out. It’ll keep being this great until I get my hair coloured again, and the results so far are showing the hair improves with every treatment. I’m sold. Don’t go blonde without it.

Can you use Olaplex at home?

After a salon treatment, your hairdresser might offer you the take-home conditioning treatment, which is recommended for weekly use to keep your hair looking and feeling healthy and full of life.

How much does Olaplex cost in a salon?

Prices will vary from salon to salon. Treatments start from £50.00 at John Frieda.
