I bought it a second time despite the high price because it’s so transformative for your hair! Turns it shiny and soft. High end product that doesn’t disappoint!

5 stars out of a maximum of 5

After just a few uses, I noticed a huge difference in the health and strength of my hair. It’s incredibly easy to use—just apply after washing and leave it in. No rinsing needed! My hair feels smoother, stronger, and more manageable.

go-to product when my hair needs some TLC

5 stars out of a maximum of 5

This is my go-to product when my hair needs some TLC. It’s an investment, but a little goes a long way. Remember to rub it between your hands several times before distributing it through the lengths of your hair. Highly recommend for repairing and nourishing damaged hair!

One of my all time favourites!

5 stars out of a maximum of 5

One of my favourite hair products of all time. K18 helps my hair stay soft and strong - even when I had bleached hair and fashion colours. A little bit goes a long way so even though small, the product lasts a long time. It's also really versatile - I can use conditioner after it (after waiting a couple minutes!), use it occasionally to maintain my hair health, or use it a couple washes in a row if my hair needs a boost! I'd really recommend K18 to anyone looking to support their hair health.
