So basically 3 years ago I started to notice more hair in the shower, but I thought it was normal so I didn’t really care anymore, but for the past two years I’ve been looking at my hair and I see how I now can see more of the scalp, so I’d like your guys opinions.
What should I do?
you should visit a dermatologist/trichologist with access to a hair microscope and see if your hairs are miniaturizing or not, if yeah then you likely have AGA though TE also miniaturizes the hair strands AGA is far more likely if that is the case. Do NOT diagnose yourself if possible, except in the rare case where you have very little to no access to derms or trichos. Also get your blood tests done (if you have AGA this is not of much use against it from this point onwards but it is shown in some studies that vit D inhibits DHT) so you may be lacking something eg. vitamin D which could have led to greater DHT which in turn might have accelerated the process.
