What change related to hair is commonly seen in steroid users?

The increase in facial and body hair among steroid users is linked to the effect of anabolic steroids on hormones, particularly testosterone. Anabolic steroids can elevate testosterone levels in the body, which can lead to hypertrichosis, a condition characterized by excessive hair growth, especially in areas normally associated with male-pattern hair distribution.

This change is part of a broader set of physical alterations associated with steroid use, including changes in skin texture and the potential for acne due to hormonal fluctuations. The hormonal effects can also result in other attributes, such as voice deepening and increased muscle mass, further contributing to the masculine traits commonly linked to steroid use.

While decreased body hair, hair thinning, and changes in hair color may impact some individuals for various reasons, they are not directly associated with the effects of steroids in the same way that increased facial and body hair is. Thus, the correct response highlights the significant androgenic effects of steroids on hair growth.
