I have the kerastase oleo relax hair masque and on the packaging it says to apply to damp hair and leave on 10 to 15 minutes or something like that. i have damaged hair and am trying to get it healthy again. would it be ok if i put it on at night and then rinsed it off in the morning? or would that be bad for my hair? will my hair feel really soft once rinsed out? or just greasy? Thanks so much!
