Never accept losing your hair at 17 yrs of age that's fucking insane for anyone to tell you to accept it. first you should go to a hair doctor and get a diagnosis, it could be a medical problem however I doubt it, start using minoxidil you can get a 3 month supply for about £50 our were ever the fuck your based. The minoxidil will start thickening the hair up and give you some regrowth however minoxidil on it's own wont give you best results you want to start on a corse of propecia, this will block the dht hormone and stop the hair loss process targeting the cause of your hair loss if its genetic. Propecia is more expensive than minoxidil gonna set you back about 50 a month. Now if you have lost alot of hair you have brought yourself some time with these treatments, you see the thing is the treatments like minoxidil and propecia are great but you will build a tolerance to them, this takes years but your best option after that is to get a hair transplant permanently fixing the issue. The con to all of this is it's going to cost you about 5,000 if you want it done correctly idk if your ritch poor but that's the best way. You can also try some shampoo to thicken it up I would recommend buying shampoo from India because Indians have some of the best and thickest hair.

I really hope this helped you because I started losing my hair around about the same age. It took about 2 years before my hairline started go and I could see through my scalp however my hairline is back because of the minoxidil I am following the exact same plan as I just told you to do dont listen to any cunt who tells you to fucking shave it because if that was the case you wouldn't be asking for fucking help on reddit

Good luck ⭐
