Testing the Speed of Hair Growth?

Dear doctor.

if the average persons hair grows about half an inch to an inch (depending on hair color) a month, how much growth would a person with “faster” hair growth be growing a month?

I sleep in a very hot/humid climate because I constantly turn the heater on in my room, and I find that my hair grows really fast. Would the heat or climate that I sleep in have any effect on the growth of my hair or am i just a person whose hair grows fast?

Are there any tests or anything that can be done to determine how fast a persons hair will grow?

I don’t know the answer to your question. I am sure that the rate of hair growth varies with the individual, their age, their state of health, and the climate. In individuals with miniaturization due to genetic balding, the hair growth slows and may stop growing altogether prior to it falling out.
