If you were going to be concerned what exactly would you be concerned about? Just curious... Did you research the subject before asking?
Hair growth, particularly head and facial hair, have everything thing to do with hormone levels. Particularly DHT. When we have testosterone in our system a portion of this hormone is converted to DHT. DHT will make some men grow more head and facial hair while others will grow less. If your body is less sensitive to the effects of testosterone and DHT, you will see slower beard and body hair growth patterns. An individual prone to male pattered baldness DHT will actually accelerate this condition.
I am prone to male pattern baldness and I see no difference in head or facial hair growth but... I do see an increase in body hair growth rate and my nails growth faster. Particularly when I am on a DHT derivative steroid (var, mast, primo, etc.).
Steroid use is a catch 22 concerning hair growth and the point I am making it is dependent on the individual.
