Do minoxidil and finasteride help stop hair loss bc of chemical damaged and give density to my hair? (photos)

One year ago I bleach my hair with pure hydrogen peroxide at home and I started to lose hair and my hair started to become thiner, I've never had any irritation on my scalp. I never did anything to stop my hair loss since then and I don't have hairless spaces, I just notice that my hair is thiner and I'm losing everyday more than the normal. My question is if minoxidil helps with hair loss due to chemical damaged
