Im almost embarrased to say that ive never tried a homemade hair mask mainly bc im really into DIY face masks. Ive always wanted to try the mayonnaise one but ive read that you should leave it in overnight so i never thought to do it. Has anyone tried the mayo one and if so do you have to leave it in overnight? I really want to try one today before i take a shower, does anyone have any suggestions? Thanks!!!!
