I'm 17 and afraid. PLEASE HELP

[Zedzee]

Hai.
I'm 17.7 years old. I noticed my hairline receding about an year ago.I used to masturbate on a daily basis for the last three years. On somedays, i would masturbate 4-5 times. Did my masturbation habit triggered my hairloss? Does ejalucation increase the production of DHT? I recently came to know that masturbation could accelerate the rate of mpb. I really want my hair. I'm really afraid to take fin cause I saw people talking about its side effects all over the internet. Is it safe for me to take fin? And If i completely stopped masturbating and watching porn, will my DHT levels come back to normal? Will my hair fall stop? What should I do? Please help me.
ps: sorry for my bad language.
