Timing of HL

[ft7we]

If a person's hair follicles are genetically programmed to be sensitive to DHT, why does the actual hair loss happen when it happens? Why is it that for some guys the HL starts in their teens/early 20's, while for others the first signs of it comes on in the 30's, 40's, or later?

I was pretty fortunate in that I made it pretty far into my 30's before I started to detect any significant HL.

Anyone have insight into this?


Thanks.
