Testosterone, estrogen, insulin and thyroid hormones play an essential role in regulating cell functions. However, they can also be a factor in causing male and female hair loss.


Testosterone is an essential sex hormone which is used in men’s bodies to develop and maintain male characteristics. It is also present and necessary in women’s bodies. When testosterone interacts with a certain enzyme in the body, it is converted into dihydrotestosterone (DHT). High levels of DHT can cause the hair follicles to become smaller and stop producing new hair growth. This results in the most common hair loss condition – androgenetic alopecia, also known as pattern baldness.


Like testosterone, estrogen is a sex hormone that is used by the male and female body. Its key role is in the development of female characteristics in women. Estrogen imbalance issues are often experienced by women after having a baby. During pregnancy estrogen levels rise, which many find boosts their hair growth. Following the birth, estrogen production drops again and can trigger a type of hair loss called post-partum alopecia. Conversely, high estrogen levels in men are associated with baldness.


Most people associate insulin with blood sugar control because of the hormone’s connection with diabetes. Insulin imbalances can also have an impact on other areas of the body. In women, increased insulin production is linked with the development of polycystic ovary syndrome, which causes symptoms including weight gain and hair loss. For men, high insulin levels are a concern as they can cause increased estrogen production.

Thyroid hormones

Thyroid hormones manage many metabolic actions within the body and it can affect hair growth if too much or too little is produced. As well as causing excess hair shedding, people with thyroid imbalances may also experience dry skin, weight gain and fatigue.
