Hair growth

Hey everyone, i’m a pre everything 20 year old trans girl and due to reasons that are entirely my fault i have very thin hair and it’s really not helping with my dysphoria. My hair is slightly curly and as of right now i put coconut oil in it 3 times a week. I have this shampoo that’s supposed to help with hair growth and it’s only been maybe a month but i don’t feel like there’s any changes. Does anyone have any advice on how to regrow hair, preferably without cutting it all off and starting from scratch?

What i’m rlly looking for is mainly treatments and foods i can eat. i’d prefer if both are more on the cheap side (i don’t have a job yet and live with my family in Mississauga)

ty for ur time lol
