I only get my hair trimmed once it's started getting bad split ends. I can always tell when it's time to get the split ends under control because my hair ends get drier and I definitely notice a lot more breakage. I usually only have to get it trimmed a couple times a year.
I leave my hair in its natural curly state most of the time, I straighten it just a few times a year, usually in the fall/winter, because during the summer I swim a lot so straightening would be pointless. Using shea butter and a little gel I do bantu knot outs on my hair to make the curls very defined. A lot of times I want it up and out of the way though so I experiment with a lot of different updo hair styles.
I haven't noticed. My hair could probably go years without a cut since it's pretty healthy. It grows about an inch a month.
Just shampoo everyday. And I curl it whenever I feel like it, although I haven't for months now. I usually just tie it into a half ponytail these days, if not down. I also dye my hair jet black every 3 months or so.
i haven't cut my hair since last spring :o it was like near my shoulders, now it's past mid-back. what do you mean by break? like split-ends? i rarely if ever use heat on my hair, so i stopped having that problem. i don't even use a hair dryer if i can help it. i use organic shampoo and conditioner. sometimes i'll put coconut oil in it, let it sit for a day, and then wash it out with shampoo at night.
