Hormones are chemical messengers that are used by the body to manage many cell and organ activities. At different stages in our lifetimes, hormone levels can alter and these fluctuations can contribute to hair loss. Some of the hormones most commonly linked to hair loss are testosterone, estrogen and progesterone, cortisol, triiodothyronine and thyroxine.
Testosterone is a male hormone which is involved with hair growth and often thought to be the main cause of hair loss. The hormone does not cause hair shedding by itself but is converted to dihydrotestosterone (DHT) by the enzyme 5AR. DHT causes the hair follicles to shrink, can increase hair shedding and stop growth. The resulting condition is known as pattern hair loss or androgenetic alopecia and can affect men and women.
Estrogen & Progesterone
Estrogen and progesterone are female hormones which can impact on hair growth and loss at different stages in a woman’s life. During pregnancy, the levels of these hormones increase rapidly and many women enjoy a boost in hair growth. After the birth, estrogen and progesterone levels suddenly drop. This can lead to a condition called post-partum alopecia which results in a period of hair loss. Changes in the levels of these hormones during the menopause can also cause hair thinning and shedding.
Stress can impact on your health in many ways including disrupting hormonal balances. One of the stress hormones that has been connected to hair loss is cortisol. It is thought that when stressed, our bodies produce higher or lower levels of cortisol than normal. These imbalances prevent the body from producing the correct levels of other hormones, such as testosterone, which in turn affects the hair growth cycles.
Triiodothyronine and Thyroxine
Triiodothyronine and thyroxine are hormones produced by the thyroid gland. If the thyroid gland does not produce enough of these hormones, it can cause a number of symptoms including hair loss. Low thyroid production (hypothyroidism) is usually managed with medication. Though the medication itself can cause hair loss, it is important for those with this condition not to stop taking it without consulting their doctor first.
