Sweetcocoa..hello!
When I read the topic of the thread, I was surprised at you. Why? You are the best of "old school" in terms of your hair care methods. And, as Nick Chavez would say, "Everything old school is definitely cool these days."
My grandmother used to put my hair in pincurls for drying when I was a child. Let me say that this I think is a fairly typical description. For visuals, the end result with a pincurl should be a twisted, circle on your head/scalp which is flat. Section your hair, as desired. Then, take a section and twist it. Then, start winding in circular fashion until you have the twisted section flat on your head/scalp. Afterwards, you want to pin it securely. To me, you have to be good with your hands to do it. My grandmother used to use bobby pins.
In terms of the curliness, I think that depends on how tightly you do the actual pincurl. Not the twisting, but the circumference of the circle. Hope you understand what I am saying.
Best advantages of pincurls for drying: little or no frizz.
Some people also do pincurls for sleeping overnight, too.
A friend over at Long Hair Community has adapted this method by doing basically multiple buns. I told her they looked similar to Bantu knots to me. Anyway, it's the same principle. She uses no pins. I've tried her method myself, but have not been able to go without using some pins. Her hair is straight. Depending on the tightness of the buns, the degree of wave to her hair. If I do it, I think my wave is not as pronounced.
Hope you are enjoying the summer!
Much Love,
