Most haircare frustration gets treated as a product problem, so people buy another product. But the things doing real damage are mostly free to fix, and fixing them makes whatever you already own work better.
Wet hair stretches and snaps far more easily than dry hair. Dragging a brush through it from the roots down is one of the most common causes of breakage that then gets blamed on the shampoo. Detangle from the ends upward, gently, ideally with conditioner still in.
Higher heat doesn't save much time and does disproportionately more damage. Most hair doesn't need the top setting, and hair that's already damaged needs it least. If your tool has a number, turn it down a notch and see whether you actually notice.
The same tension in the same place every day causes breakage in a visible line, and it's slow enough that people don't connect it to the habit. Move the position, loosen it, and use something soft.
Shampoo is for the scalp, where the oil is. Your ends get cleaned enough by the runoff. Scrubbing them directly dries out the part of your hair that's already the driest — and then people buy a mask to fix it.
Styling soaking-wet hair means far longer under heat. Letting it air-dry most of the way first cuts heat exposure dramatically and costs nothing but a few minutes.
If your ends look bad, no product fixes that — and a trim is usually cheaper than the mask you were about to buy. Start there, then judge what your hair actually needs.
Almost none of this costs money, and all of it makes cheap products work better. Fix the habits first; then decide whether you still have a product problem.
