So having the bright red color that I do, requires that I maintain My hair a certain way. On thing that I have to do is not wash it for 2 weeks at a time. You can imagine, after those 2 weeks, I have REALLY greasy hair! It can maintain shapes (as in, if I brush it back, it looks like I just got out of a pool because it's slicked back). So I brush it side to side and also back and show iff it's amazing greasy staying power. Oh the power of hair grease! Hey it's what we all naturally produce OK? And it's actually good for your hair :)
