What are Aromatase Inhibitors?

To find out the connection between aromatase inhibitors and hair loss, let’s first understand what aromatase inhibitors(AIs) are and what are they used for.

Aromatase inhibitors are a class of drugs used in the treatment of breast cancer. Postmenopausal women are often at a higher risk for breast cancer. It is also used for the treatment of men who suffer from gynecomastia which is an increase in the amount of breast gland tissue. These can be caused due to an imbalance of the hormones estrogen and testosterone. AIs, lower estrogen levels by blocking an enzyme in fat tissue (called aromatase) from changing other hormones into estrogen. These drugs are especially given to women who have already attained menopause and are suffering from breast cancer. The AIs therapy given to cancer patients leads to hair loss and hair thinning.

Hair thinning and, in some cases, hair loss experienced by breast cancer survivor patients can be due to other factors such as chemotherapy agents. Endocrine therapy-induced hair loss in association with AIs and tamoxifen treatment has been reported but is again not permanent. Complete hair loss due to any type of aromatase inhibitor has not yet been clinically proven. It is definitely associated with hair thinning, but it is not a permanent problem. 

A good diet consisting of proteins, vitamin C, and omega-3 fatty acids can change the hair-thinning cycle. A good dermatologist can provide proper recommendations for achieving the healthy hair that you seek. The treatments totally depend on the diagnosis, as one treatment does not fit all.
