What does testosterone do to get a goatee past the stubble phase?

Testosterone is a hormone that plays a key role in the development of facial hair, including a goatee. As testosterone levels increase during puberty, it stimulates the growth of facial hair, including the hair on the chin that forms a goatee. To get a goatee past the stubble phase, individuals with higher levels of testosterone may experience faster and thicker hair growth, resulting in a fuller and more defined goatee. Additionally, proper grooming and maintenance, such as regular trimming and shaping, can help promote the growth of a well-defined goatee.

Testosterone does not directly affect facial hair growth beyond puberty. Facial hair growth is primarily determined by genetics and is not significantly influenced by testosterone levels post-puberty, except in cases of extreme hormone imbalance or disorders.
