Will taking steroids for bodybuilding affect my transplanted hair?

Hi, Thank you for sharing your query. Definitely steroid usage will not affect the transplanted hair. But i dont recommend steroid supplements for body building .  

Steroids are not safe to use if you don’t have the recommendation of a doctor. If you are genetically predisposed to androgenetic alopecia, your body already has higher levels of DHT than it needs – taking steroids is known to produce more DHT, which, in turn can accelerate male pattern baldness.
Steroids will not cause hair loss, but they will play a large part in drastically increasing your hair loss if you already have male pattern baldness.
In theory transplanted hair follicles will be safe from DHT and high amounts of androgens. Nevertheless, you should consider that your remaining native hair follicles may not be resistant to DHT and may undergo hair loss if DHT is allowed to "attack" them. If those remaining hairs undergo miniaturization, you may require another hair transplant surgery.

Since the transplanted follicles are resistant to DHT, they will not fall out in normal circumstances. The use of steroids may not only affect the transplanted hair but also the native hair present on the scalp. The general usage of steroids for body building is not advocated due to its potential adverse effects.

Hi, How are you. Steroid use will not affect the transplanted hair. Reason being is because the transplanted hair is genetically programmed to grow for life. However, Steroid use will be bad for native hair and will in fact ensure you to lose more hair. I would strongly advise against it. 

Steroids will accelerate the loss of any hairs that are affected by the DHT that causes hair loss in MPB. However, the hair that is used in a transplant is immune to the DHT, so it will not fall out.
