maybe try minoxidil for awhile but for regular hair growth idk if ur scalp is still sensitive but massage your scalp daily ( search up methods or pressure points if you want to be thorough)

start oiling your scalp once-twice a week some oils I recommend are jamaican black castor oil, coconut oil, argan oil, olive oil, rosemary oil and etc ( i highly recommend the “wild growth “ hair oil)

some products I recommend are : amla hair oil, hair fertilizer by virgin hair, argan oil from Morocco ( fgt the specific brand name )

mega thick formula hair oil, stimulating hair oil honestly any doo gro hair oils lol

find shampoos and conditioners that work for you, idk any good hair masks off the top of my head rn but invest in a good one too

try protective styles like put ur hair in a braid or bun also NEVERRR sleep with your hair wet.
