22 Year Old Seeing Hair Loss on Back and Sides of Head

Hi, I am a 22 year old male. Since the last 2,5-3 years I slowly see my hairline reseeding in my temples, and also thinning over my complete head. But I have read on the internet that the hairs on the back of your head and on the sides are immune for the DHT-hormone. So I was wondering why I see those area’s also thinning?

Thanks

You need to see a good doctor who can do miniaturization mapping to determine what is going on. It is not usual to see thinning all over your head like you describe, but without an examination, I’d just be making guesses as to what could be going on.
