While there isn't a single hormone that gives hair, androgen hormones, often referred to as "male" hormones, like DHEA and testosterone, play a significant role in overall hair growth. These hormones influence the hair cycle and follicle structure.
However, the role of androgens is complex. While they contribute to hair growth in some areas like the scalp, they can also cause excessive hair growth in others, like the face and body, leading to conditions like hirsutism. This is because androgen levels can fluctuate throughout life and imbalances can disrupt hair growth patterns.
For example, postpartum hair loss is caused by hormone changes during and after pregnancy, while stress can also trigger hair loss by impacting stem cells responsible for hair growth.
Therefore, it's essential to understand that hair growth is influenced by various factors, including genetics, nutrition, and overall health, with hormones playing a crucial role in regulating the hair cycle.
