I was just curious to how the levels of DHT change in the body over time. Do DHT levels rise to some sort of critical level before the onset of baldness? or do the follicles just become less resistant to DHT as one ages? Also is there a difference in DHT levels in bald and not-bald males?
Yes, DHT levels change as we age, but the level of DHT does not necessarily correlate with balding or androgenic alopecia (AGA). It is your genes that makes you susceptible to the DHT impact on hair that produces balding. In other words, you can have a high level of DHT and if you do not have the gene for AGA, you will not lose hair. Or you can have a very low level of DHT and have the gene for AGA and be bald. As DHT comes from testosterone, it is your testicles that are the supplier of the hormones that cause baldness. If you did not have testicles, then the balding process would stop, but your hair would not come back.
