Hair loss related to hormonal imbalances is common and can be caused by various factors. Here’s a comprehensive overview to help you understand the primary causes, medical conditions involved, and other influencing factors.
A derivative of testosterone, DHT binds to hair follicles, causing them to shrink. This shortens the hair growth cycle and eventually leads to hair thinning or cessation of hair production.
Often hereditary, this condition causes hair follicles to become more sensitive to androgens like DHT, resulting in progressive hair thinning in genetically predisposed individuals.
Hormonal shifts can disrupt the hair growth cycle:
Conditions such as Polycystic Ovary Syndrome (PCOS) and thyroid issues (hypothyroidism or hyperthyroidism) cause hormonal imbalances that can lead to hair thinning.
Particularly in PCOS, high insulin can increase androgen activity, contributing to hair loss.
Elevated cortisol levels from stress can induce a shedding phase called telogen effluvium.
A family history of hair loss increases susceptibility due to inherited sensitivity of hair follicles to androgens.
Recent observations have indicated that some patients using GLP-1 receptor agonists (medications used for diabetes, weight loss, and metabolic health) may experience hair shedding or thinning. The exact mechanism is still under study, but it is thought to involve hormonal modulation and changes in metabolic pathways affecting hair follicle cycling. If you are on GLP-1 therapy and notice hair changes, consult your healthcare provider for personalized advice.
Hormonal hair loss is multifactorial, involving genetic predisposition, hormonal imbalances, medical conditions, and external factors like stress. Understanding the underlying cause is essential for effective treatment.
If you're experiencing hair thinning or loss, consider consulting a healthcare professional or dermatologist to determine the cause and explore potential treatment options.
