Not only is Zara McDermott one of our favourite TV personalities, but we love how she NEVER hoards any of her beauty secrets from her fans, including her skincare must-haves and haircare she uses to keep her golden locks looking so healthy and thick all of the time.

　　One product the former Made In Chelsea and Love Island star recently shared was her obsession for the K18 hair mask, which is also loved by the likes of Hailey Bieber, Selena Gomez and many other celebrities.

　　Posting a photo to her Instagram story of the K18 hair mask and the K18 molecular repair hair oil, Zara confirmed that they had been life-savers during her work trip to Thailand. After being introduced to the hair mask by a friend previously, Zara confirmed that she ended up ordering several bottles straight after using it, and now uses it twice a week.

　　She said in the post: This hair mask has saved my hair on this trip!...Im not sure I could live without these hair products in this humidity. The oil is amazing as well if you want to try both together... Theyre a brilliant invention!

　　While most of us are guilty of dying our hair and using a lot of heat on our locks, we need all the help we can get, but were not the only ones. Many celebrities including Khloe Kardashian, Selena Gomez, Hailey Bieber and even Rihanna swear by K18 products, specifically the powerful hair mask.

　　However, weve also got an on-ground review too, from our very own senior fashion and beauty writer Samantha Price, who can confirm it has made a dramatic difference to the texture of her hair. She said: I was recommended K18 by my hairdresser after having K18 treatments at my salon, and honestly, it has made such a difference to the texture of my hair.

　　I have wavy hair thats prone to frizz and using K18 in my routine makes my hair ridiculously soft and smooth - literally like Ive had it done professionally! I use this treatment when my hair needs an extra bit of TLC. Just apply two pumps in your hands, comb it through your hair and blowdry for best results - no need to rinse, which is a massive bonus for me (and anyone who loves a low-maintenance haircare routine).

　　Luckily, both products are 20% off now too. Run, dont walk ladies...
