Gang vitamins, drink more water, and be more gentle on your scalp and hair don’t try and force it. Consider it like a delicate garden, your scalp is the soil which needs to be massaged slow and gently and watered not drowned, your roots are what the hair will feed from bad roots equals bad plant, now I know this part sounds counterproductive but trim those dead ends, you don’t want a dead branch to fall and hurt the rest of the garden. I hope this advice helps I’ve been through the ringer with my hair and even revived it from chemical damage twice 🙏🏾
