I know what’s the difference between two cases? DHT miniaturised and non-DHT miniaturesed? What else causes miniaturisation except DHT?
If the miniaturization is DHT dependent, then it occurs in the hairs of the scalp that are susceptible to DHT from genetic causes (i.e. Norwood Class 7 pattern patients). I have believed that the juvenile hairline in most Caucasian men have hairs that have a limited life (i.e. develop apoptosis when the clock reaches its genetic finality which may vary in men between ages 17-29). I have met some men with a Norwood Class 7 pattern who had a persistent juvenile hairline that stayed strong into their 60s. That is why I don’t believe the juvenile hairline is not sensitive to DHT and its loss is apoptosis tied to some biological clock.
