Talk to Dermatologist on Having Hair Fall

I live outside homecity due to work & studies. Eat outside food. Used to style my hairs alot by heat or market products. Now doing oiling twice a week. somehow hair falling stopped by like 40% but hairs aren't growing back. Thinning hairs from middle of the scalp showing signs of partial baldness but its in early stages. Facing this issue from past 2-3 years
