It seems so simple but for me to do on my own it was hard to do and didn't come out right. My roots were nowhere near as straight n silky as it was when I got it done at the salon.
Problem 1 was I don't really know how to rollerset, so that was already messed up from jump. Problem 2 is that my hooded dryer which can normally accomodate my big head could not accomodate my big head and the big rollers. Problem 3 was blowing out while using a round brush took too much arm and wrist dexterity that I DO NOT have.
It wouldn't call it a disaster b/c my hair didn't look worse than when it started or worse than it ever had, but it was definitely NOT like the salon experience and for that reason I would probably not even bother doing it on my own again.
