DHT's and hair removal

I reading that dht compounds such as those found in some kinds of steroids, will thin and promote hairloss on your head at the same time increase body hair growth. Is this true? I know for a fact the hair will thin on your head but wasnt sure about hair GROWTH on your body…?
(not looking for a lecture on steroids please just some help with the question)

Yes, this is a frequently occuring effect.

Would this be a rare side effect or something that is more or less almost guarenteed likely to affect my laser treatments? are there any DHT blockers that can be taken?

It almost seems like nature’s cruel joke: the very same element that causes male-pattern baldness also spurs increased body hair growth. DHT (Dihydrotestosterone) is the product of testosterone mixing with the enzyme 5 alpha-reductase. DHT then binds to the receptor sites of healthy scalp hair follicles, essentially choking the life out of them by limiting blood and nutrient channels. However, DHT plays a crucial role in stimulating body hair growth during adolescence, so an overabundance in the body only spurs more growth.
