Top 7 Best At-Home Keratin Treatments UK (2024)

Picture this… your unruly, unmanageable, and frizzy hair is suddenly smooth, healthy, and sleek. Imagine going on holiday to the seaside without having to worry about your hair, knowing it looks gorgeous.

Ever wish you had the confidence to run through the rain without fear that your hair will suddenly turn into a ball of frizz? It’s just so disappointing when you’ve put so much effort into smoothing and styling it through blow-drying and flat ironing – only to be left with bad hair the moment the weather turns. 

If you’re tired of bad hair days, here’s finally some good news! It’s possible to have a good hair day for months on end. All you need is a keratin treatment. 

With a keratin treatment, you can straighten your hair permanently and maintain these incredible results for up to 3 months. Not only will your hair be smoother, but it will also be much easier to maintain, healthier, shinier, and straighter, so it will always look good – whether it’s after getting up in the morning or after getting caught outside in the rain.

However, there is one problem. There are now hundreds of keratin straighteners out there, some of which unfortunately contain formaldehyde or other toxic chemicals that can destroy your hair. In some cases, they may lead to hair loss.

If you don’t want to ruin your hair but want to have smooth, sleek, straight, healthy, and low maintenance hair for up to 3 months, you should definitely choose the right keratin straightener.

Fortunately, you don’t have to waste time trying to find the best one. We’ve done the tests and in this article, we reveal the 7 best keratin treatments that you can easily apply yourself at home.

Premium Keratin Hair Straightening by KERATASTIC has already won over countless men and women worldwide. It is from Germany but is now available in most places around the world. This authentic formula is made without formaldehyde or other harmful chemicals and provides impeccable results, which is why this product has more than earned the distinction of first place for this category.

KERATASTIC’s Keratin Treatment is considered by many to be the best product for permanently smooth, straight, and sleek hair. Due to its high quality and excellent results, KERATASTIC is now also used by many hairdressers in salons who use it to straighten their customers’ hair.

So, with KERATASTIC, you get a salon-quality product with excellent results at a comparatively affordable price. Keratin hair straightening at the hairdresser often costs hundreds of Euros. With KERATASTIC you get the same results at home for a fraction of that cost.

Another big advantage is that while other keratin treatments make your eyes burn and leave your hair stinking for weeks afterwards, KERATASTIC products are the opposite: no toxic chemicals, no burning sensation in your eyes, and your hair is left with a lovely fragrance.

Also, you can wash out the KERATASTIC straightener right after the treatment and don’t have to wait 3 days like other products.

For us, the keratin hair straightening formula from KERATASTIC is the clear winner in all categories: Quality, results, and application.

Next up, we gave GK Hair Global Keratin a try – a popular DIY keratin treatment. This little bottle promises straight and shiny hair, though claims only the best results if used together with its own brand of shampoo and conditioner. This has to be left it in for a whole hour, though, before you can dry it as usual and flat iron it out. So, that’s a lot of steps. Plus, it’s suffered from many negative reviews that say it leaves your hair more damaged.

The Complex Brazilian Keratin Hair Blowout Treatment claims that it’s a formaldehyde-free formula, and promises smooth and straight hair – although the process is a bit longer and more involved. Those with long manes will really need to spackle it on there, and you’ll need to buy more than one set to get the results. However, many users have complained about this product’s smell. Even if it’s not formaldehyde, there’s some kind of chemical that leaves your eyes burning. 

One thing that Kérastase has going for it is that it’s a simple DIY treatment to use at home. While many users have loved the way their hair looks after using it, gaining sleeker and smoother results, there are many reviews citing that this product fell short. It’s also incredibly expensive, and while it’s often recommended by hairdressers, it’s quickly falling out of favour.

Magik Beauty contains extra amino acids to help hydrate and revitalise hair. Though it claims its results last for 3 to 5 months, it doesn’t seem to keep hair straight. If your ultimate goal is to still have curly locks, this may be for you, though you’ll definitely be disappointed if all you wanted was poker straight hair – especially at this price.

Some say that you uncover your ideal hair with CGIFY’s Magical Keratin Hair Treatment Mask. The brand claims to contain naturally derived extracts that nurture your hair from the inside out, promising to repair damage in 5 seconds. But words and deeds are two very different things; we’ve found more users were less than thrilled with the results. The instructions are also far from clear, leaving you in a tizzy about whether you’re doing it right. 

The Vitamins Hair Mask Keratin Treatment boasts sensually soft, shiny and silky hair in just minutes. Unfortunately, for many users, the results have left their hair limp and greasy. The smell is hard to get past too, as it’s intensely masculine. Perhaps men won’t mind it, but women wanting to straighten and smooth their hair have found it a turn-off.
