It's no exaggeration to say the Black Friday beauty deals are coming in thick and fast. Brands like Sol de Janeiro and Charlotte Tilbury are churning out the offers, all with hefty savings. Another brand worth stocking up on? K18. Known for its revolutionary haircare products (and a brand new dry shampoo) that sell out time and time again, there's no better time to acquaint yourself with this beauty editor favourite, which is now offering major discounts for Black Friday.

These formulas are considered game-changers for damaged and over-processed strands - I should know. I've been a (not so) natural blonde now for the last 10 years and am only too aware of the damage that bleach can leave in its wake. Thankfully, it's this biotech-driven brand that I credit for restoring my own hair. While it's not yet perfect, it's certainly softer, smoother, and more supple than it has been in a very long time. K18 claims to restore hair from the inside out, and, after seeing the proof in the pudding, I'm inclined to agree. Here are the unmissable discounts K18 are offering for Black Friday this year.

Beauty editor Rachael Martin says: 'If I could only have one hair product for the rest of my life (aside from shampoo, obvs) this is it. The K18 Leave-in Molecular Repair Hair Mask, works miracles. The leave-in treatment mask (designed to restore hair in just four minutes) works from the inside out. Because it penetrates so deeply, even the most extreme damage is remedied thanks to a boost in core strength. I've been using it since January and have seen a reduction in split ends, bolstered strength and added shine. Would recommend - especially for fellow blondies.'

Pros

  • Vegan
  • No need to rinse

Cons

  • Expensive when not on offer

Price: £20.25 (was £27)

Beauty editor Rachael Martin says: 'As someone who has naturally greasy strands the idea of a hair oil never thrills me. If you use just a small amount of this one, however, then you can't go wrong. I like to warm a pea sized amount in the palms of my hands and work through the lengths and ends of wet or dry hair. Again, K18 say it tackles 'the deeper-level damage that can cause frizz for a smoother, sleeker appearance.' And I do think it works well. I have wild flyaways and this really helps to tame them -there's super ingredients sunflower, avocado and squalane to thank for that. And it's also brimming with heat protectant. A multitasking hero!'

Pros

  • It's a small bottle but a little goes a long way
  • Silicone free

Cons

  • If you use too much you hair will be greasy

Beauty editor Rachael Martin says: 'I love a good in-shower lather and this one really delivers without stripping or drying. Designed to look after the 'scalp’s own protective barrier by replicating the hair’s natural pH level,' my dry, damaged hair looked considerably more nourished after the first wash. I'll go in with a double shampoo to ensure any product build up is whipped away. Even when I'm skipping the conditioner in favour of the leave-in mask my hair feels clean without being dry. I always think my colour looks more vibrant, too.'

Pros

  • Replicates the hair’s natural pH level

Cons

  • £39 usually - an expensive shampoo

Price: £29.25 (was £39)

Beauty editor Rachael Martin says: 'Luxury, bottled. This creamy conditioner coats hair with a protective layer of protein to make strands more resilient in the long run. Designed to 'protect against UV rays, styling and environmental damage for up to three days after use,' I like to think that this conditioner is an investment for my hair - and it definitely looks smoother and shinier afterwards.'

Pros

  • Formulated with K18PETIDE™ to replace protein
  • Protective effect lasts up to 3 days

Cons

  • Thicker hair types may get through it more quickly

Price: £20.25 (was £39)

Beauty editor Rachael Martin says: 'If you're after an effective but gentle detox then K18's could be just the ticket. Also powered with the patented K18PEPTIDE™ (to restore protein) this always feels like the ultimate refresh for hair that needs a bit of a kick into action. While it doesn't necessarily feel nourishing, it does leave my hair feeling weightlessly clean. I'd recommend using it before a hair treatment.'

Pros

  • Colour safe

Cons

  • Can't use every wash day - swap for the damage shield
