My hair is usually in twists or braids, it takes less than 5 minutes to style them. If I'm wearing it out in its nappy/coily/curly/kinky state, it also takes about 5 minutes to undo my plaits and comb the hair out and push it back into a puff. When my hair is straightened, I usually wear it up, so again less than 5 minutes. I think if my hair used to take long to deal with, I'd not have the wonderful relationship I have with it.
Keep in mind, braiding, twisting, flat ironing...do take a while to do. But while they do take long, the happen once in a blue moon because I wear my braids and twists "forever" and I'm usually distracted by a TV show or movie when putting them in for the first time. I don't flat iron my hair often so when I do, it's one of those things that I am mentally prepared for so at the time I don't mind the time it takes. But now that I'm not thinking about it, if you suggested it, I'd say no coz I don't feel like putting all that time in. The way I wear my hair goes well with my lazy mode.
