Btw, you have conviced me to buy the Kerastase Genesis serum! Since i also have quite dry/flaky hair that might be eczema prone (since i have eczema on my skin), so kinda hoping it will work for me too ☺
K18 doesn't have the same effect on the hair as a mask. Any mask leaves the hair silky smooth, K18 is more of a repair treatment, so comparing it with any masks is just inaccurate.
