A must have

Best product for damaged hair! I use it every other week just once.I don’t colour my hair, but I do have some heat damage and this made a huge difference. My hair is now smooth, shiny, and soft to the touch. I highly recommend it to anyone who’s been waiting to achieve their dream hair!

[This review was collected as part of a promotion.] My thin, highlighted blonde hair ALWAYS needs volume and lift! K18 has made it simple and easy for me to achieve this, without leaving my hair greasy or hard to brush. I love this set, and I think it's a great gift, too!
