Since I bleach my hair before i dye it all the colors of the wind, I try to really baby it at other times.
I rarely use heat styling on my hair- maybe once a month I’ll use a curling iron and a blowdryer maybe once every two months. But my hair tends to lie rather flat if I don’t do /anything/ with it, so I use a lot of no heat styling tricks. Usually, I just style it by waiting until it’s half dry after a shower, and then putting it into one of a few hair styles so it can gain some shape and texture as it dries the rest of the way. This doesn’t work on everyone, but if you have naturally straight hair with a similar medium-fine hair diameter like I do, it works great! (If you’re not certain what type of hair you have, this article on Headcurve can be really helpful! I have a 1b hair type, meaning it’s fine and generally straight, but not so fine that you would see a lot of scalp showing through.)
My current favorite no heat style is two low buns in the back. I specifically also twist the hair as I’m putting it into the bun. I then either sleep on it or chill for a few hours while I’m working.
Once I take it out- voila! Fun curls and texture. As you can see in the picture, it’s still just a little damp when I take it out, so I finger comb it and zhush it a little. By the time I’m done with my makeup, it’s all dry and looks great! It’s really simple and I quite like it. :)
I personally don’t tend to use a lot of product on my hair unless it’s absolutely necessary. I don’t even usually use frizz free serum on my hair, as it can look greasy really quickly. I’ll often just put a little lotion on my hands at the end of my prep, rub it in, and any small amount that’s left, i’l just lightly finger comb through my hair - ends first, than just a very light hand on my roots.
