Hair loss can be a distressing experience for anyone, but especially women. After all, societal beauty standards promote thick, shiny hair as the ideal. Various factors contribute to hair loss in women, from genetics to allergies. One often overlooked but critical cause of hair loss is hormone imbalance. Hormones play a vital role in hair health and regrowth, so certain deficiencies can lead to shedding, thinning, and even balding. The good news, however, is that hormonal hair loss can be treated and even reversed simply by restoring certain hormone levels.
Hormones play a pivotal role in regulating neary all bodily functions, including hair growth. Fluctuations or imbalances in hormone levels can impact the hair growth cycle, which involves a carefully regulated system of growing, resting, and shedding. Hormones that can negatively affect the hair growth cycle include:
Among other things, estrogen promotes hair growth and maintains its thickness and health. During pregnancy, elevated estrogen levels often lead to thicker, fuller hair and stronger nails. However, after childbirth or during menopause when estrogen levels drop, hair loss or thinning might occur.
Progesterone is another hormone responsible for myriad functions in the female body. One of these roles is to prevent the conversion of testosterone into dihydrotestosterone (DHT). Low progesterone levels can result in higher levels of DHT, which can cause hair follicles to shrink resulting in premature hair loss. This type of hormonal hair loss is often most noticeable around the crown and hairline.
Imbalances in thyroid hormones can impact hair growth by signaling more hair follicles to “rest” during a cycle, which causes thinning due to lack of regrowth to replace shed hairs. A thyroid imbalance can also cause hair to be more brittle and fall out more easily. Thyroid-related hair loss is not limited to the head. You may also see a thinning of the eyebrows.
Known as the stress hormone, elevated cortisol levels negatively affect regulation of the hair follicle. Studies have shown that cortisol can reduce the synthesis of certain skin elements, including hyaluron and proteoglycans. This can cause excess shedding and thinning of the hair.
Corticosterone is another adrenal hormone. When present in high levels during periods of stress, it prevents the follicles from secreting GAS6. This is a molecule that activates the hair follicle’s stem cells. Hair remains in a resting period rather than starting a new growth period.
Diabetes is notorious for contributing to hair loss. In addition to genetics and circulatory issues caused by the disease, hormonal imbalances related to insulin resistance can also contribute to hormonal hair loss in women. High levels of blood glucose cause hair to fall out more rapidly than it can be replaced, leading to thinness or bald patches.
There are three main categories of hair loss, each with specific causes and presentation:
If you are experiencing signs of hair loss and you are unsure of the cause, your first step should be to consult with a functional health care provider. This is because functional medicine will focus on the underlying cause of your hair loss, and not just ways to stimulate hair regrowth. This may include one or more of the following strategies:
Hormonal imbalances can significantly impact hair growth in women. Understanding the role of various hormones and their effects on the hair growth cycle is essential for proper diagnosis and effective management. Seeking professional guidance and adopting holistic approaches tailored to individual needs can help women address hormonal hair loss and maintain healthy, vibrant hair.
