Understanding How Hormones Can Impact Hair Loss

Hormones, it's a topic that many people are curious about. Whether you're experiencing hair loss yourself or are simply interested in understanding the science behind it, this information may be valuable to you.

Androgenetic Alopecia and DHT: The most common cause of hair loss is androgenetic alopecia, often linked to the hormone dihydrotestosterone (DHT). In individuals with a genetic predisposition, DHT can cause hair follicles to shrink, resulting in thinner and shorter hair until they eventually stop growing altogether.

Thyroid Hormones: Both an overactive and underactive thyroid can disrupt the hair growth cycle. An overactive thyroid (hyperthyroidism) can make hair become fine and brittle, while an underactive thyroid (hypothyroidism) can lead to hair loss.

Cortisol and Stress: Chronic stress can lead to increased cortisol levels, which can disrupt the hair growth cycle. This is often referred to as telogen effluvium, where hair prematurely enters the resting phase and is subsequently shed.

Estrogen, Progesterone, and Hormonal Fluctuations: Hormonal fluctuations, such as those experienced during pregnancy, menopause, or while using birth control, can impact hair thickness and growth. Some women may notice increased hair shedding during these times.

Testosterone and Hirsutism: In some cases, high levels of testosterone in women can lead to male pattern hair loss.

Insulin and IGF-1: High levels of insulin and insulin-like growth factor-1 can contribute to hair loss, particularly in individuals with insulin resistance or diabetes.

Adrenal Hormones and Conditions: Conditions affecting the adrenal glands, such as Cushing's disease, can lead to hair loss due to hormonal imbalances. It's important to note that the interaction of hormones and hair loss is complex and varies from person to person. If you or someone you know is concerned about hair loss, I would recommend consulting a healthcare professional or dermatologist who can assess the specific situation and recommend appropriate treatments or interventions.
