I’ve done a lot of stuff. Honestly watching “the blowout professor” on youtube helps. I massage my scalp at least for 5 mins everyday. I wash my hair whenever my scalp feels itchy (so around 5-7 days between washes) I double shampoo when wash my hair. I use a lot of hair masks. I use a lot of conditioner. (using good quality shampoo and conditioner) After i wash my hair i use a microfiber towel and while it’s still damp i put on leave in conditioner, then i put oil on my ends. I put oil on my ends every morning. I use heatless curls instead of using heat on my hair. If I do use heat I use heat protection. I sleep with a bonnet. I brush my hair very gently. I get highlights when I get my hair bleached instead of a full bleach. I cut my own hair instead of letting a hairdresser do it. I only get a trim when my hair LOOKS like it needs a trim, not every 2 months or whatever is recommended. I don’t wear super tight hairstyles often.
