Soslychic -
After moisturizing my ends, I fingercomb my hair on each side of my head towards the back, making it as smooth as possible. I don't yet have a rat tail comb (or a brush) for any smoothing but so far so good.
I then pull up all of my hair like I'm going to make a high ponytail.
Then with one hand I "roll" or scrunch my hair into itself sideways, starting with the top part, towards the right (can be either side) and while holding the roll, I insert a Good Days hair pin vertically, inside of it from the top. The roll is a vertical roll in the back of your head.
Then I do the same with the lower part of my hair, using another hair pin or two (or how many you want to use). The result should look like one smooth vertical roll up and down the back of your head. You shouldn't be able to see the hair pins - they should be inside of the roll. I'll see if I can find a pic of it.
After doing it a few times (never did it before I joined this board), I can now do it without looking in a mirror.
The ends will look wierd (all curled up) when you take it down, but I am assured by others on this board that no harm is done to the ends and you can grow your hair very long this way.
I hope this helps.
