The best at-home keratin treatments for smooth, shiny and frizz-free hair

RRP: £49.99 for 75ml | Type: Blow dry cream | Key ingredients: Keratin, rosemary leaf extract, soy protein

Blow drying your hair can be a mundane task, but Keratin Complex's Infusion Keratin Replenisher makes the process so much better. Aside from nixing frizz (which most people with thick hair experience post-blow dry even if they use the very best hair dryer), we found that it actually cut our drying time in half – even on coarse hair types.

It's also made with a medley of hair-nourishing ingredients – keratin being the main one, responsible for smoothing out locks, as well as rosemary leaf extract to condition and soy protein to stop frizz in its tracks. If you're on the fence about at-home keratin treatments, we'd say give this line a go above all others.

RRP: £37 for 150ml | Type: Blow dry cream | Key ingredients: Keratin, ceramides

Humid climates are no match for this keratin-enriched pick from Kérastase. It's made with specially-formulated keratin that smooths out the hair without compromising movement and bounce, as well as ceramides to shield hair against damage at the hands of hot tools or intricate styling.

While testing, we found that it significantly reduced flyaways and made our hair easier to style. We also loved that the cream was lightweight, didn't feel sticky on strands and smoothed frizz on thinning hair, as well as medium textures. Thicker and drier hair types may want to opt for a richer formula, but all in all, this definitely has our stamp of approval.

RRP: £2.99 for 50ml | Type: Deep conditioner | Key ingredients: Keratin, jojoba seed oil, hydrolysed rice protein

Strands in need of some TLC? This keratin-enhanced deep conditioning mask from Hask will do just the trick, delivering the hair-boosting, frizz-defying benefits of keratin and jojoba seed oil directly to your strands.

The single-use packets, though not particularly environmentally friendly, are incredibly easy to use (we were able to get two uses out of one packet despite having a long hairstyle). We simply applied half the packet from mid-hair to ends, massaged it in, and let it sit for 10 minutes. After rinsing, our tester's hair felt soft, silky and ready for styling. Pro tip: make sure to wash it out thoroughly, as it can otherwise leave behind a wax-like residue.

RRP: £45 for 50ml | Type: Oil | Key ingredients: Keratin, vitamin E, Tahitian gardenia flower extract

Healthy-looking hair, here you come. Chock-full of botanicals and strand-conditioning ingredients, this hair oil from Virtue is impressively lightweight for the amount of shine and smoothness it delivers. The big ingredient here is Alpha Keratin 60ku, which is a human keratin protein that mimics the keratin you find in your hair, skin and nails. At £45 per bottle, it's far from being one of the most affordable on our list, but we found that a little product goes a long way so the bottle should last a while.

It's also super easy to use, simply apply it to damp hair, much like many of the best hair styling products, then top off with a bouncy blow dry for best results. The formula is also transparent (versus other oils, which are yellow), so you won't have to worry about it affecting your colour, which will be a blessing to anyone with balayage or another painstakingly created hair colour.

RRP: £14.98 for 177ml | Type: Leave-in spray | Key ingredients: Keratin, jobjoba oil, argan oil

Often used in upscale hair salons, this pick from CHI is a solid option no matter your hair type. It's good for those with dry, damaged hair because it contains nourishing jojoba and argan oil, but it also helps manage frizziness and prevent further breakage thanks to the keratin in the formula.

Unlike many leave-in conditioners, this one is in spray form, which means you're less likely to over-apply or be left with a weighed-down feeling. During testing, we were impressed with how easy it was to apply (it literally only requires a few spritzes on wet hair) as well as the floral fragrance, though some may find it overpowering.

RRP: £29.99 for 295ml | Type: Leave-in spray | Key ingredients: Keratin, green tea leaf extract, sunflower seed extract

It's a 10 is a brand known for its original leave-in conditioner, but if you're looking to up the ante, the keratin version is well worth getting to know. As the name implies, the product is meant to do 10 different things to your hair, smoothing out frizziness, detangling, and sealing the hair cuticle among them.

We're big fans of this product because it just works; every time we used it post-shower and proceeded with styling, our hair was left super soft and with no frizz in sight. While the product could do a little more for strands on the shine front, we were still impressed with its ability to make split ends less visible and our hair appear healthier overall.

RRP: £12.99 for 2x 385ml | Type: Shampoo & Conditioner | Key ingredients: Keratin, ceramides, argan oil

Keratin, argan oil and ceramides the dream combination that make for smooth-as-butter hair here, which is why we're partial to this best shampoo and conditioner duo from OGX. During testing, we found that the shampoo thoroughly cleansed the hair but didn't leave it feeling 'squeaky clean' (which is actually a sign your strands are dehydrated).

As for the conditioner, it boasts a thick, deep conditioning mask-like texture we found to be especially helpful for making the ends look and feel healthier. Just be careful of using too much product, as it could take a while to rinse out on fine strands or those prone to build-up. Overall, if you're looking to incorporate an at-home keratin treatment into your routine in an easy, subtle way, we say definitely check these out.
