If the cause was just AGA wouldn’t it be falling out specially from the AGA affected areas? (Photos)

ild itching is actually a pretty common complaint in androgenetic alopecia (AGA), and I’ve seen it in many patients. The itching often happens due to inflammation around the hair follicles as DHT (dihydrotestosterone) starts to affect them. The miniaturization of follicles can irritate the scalp, which may cause that mild itching sensation you’re experiencing. It’s not typically from new hair growth but rather the changes occurring in the follicles as they weaken.
Itching can also occur when hair is entering the telogen (resting) or exogen (shedding) phases, as the scalp can become slightly irritated when hair is shedding or preparing to shed.
As for your naturally thin curly hair, it won’t necessarily make the miniaturization process worse or faster, but it might make the effects of AGA more noticeable sooner. Because curly hair can give the appearance of more volume, when thinning occurs, the drop in density can stand out more quickly. Thin hair strands by default are more prone to looking sparse as they miniaturize, but the actual speed of miniaturization is driven by genetics and DHT, not hair texture.
