My fav

Great value for money, absolutely love the leave in and the heat/volume spray doesn’t leave me hair greasy!

not worth it

the K18 mask is amazing. However, the volume spray was useless, I did not see a noticeable difference to justify the price, and it made my hair feel disgusting, it was rough and lacked shine after using the spray.
