How Hormones Can Affect Hair

Hormones play a significant role in regulating hair growth, and imbalances can lead to various hair loss problems. How hormones affect hair health, the different types of hormones that impact hair follicles, and the effects of hormone imbalances on hair are all complex topics. We will explore them to help you understand what you can do about them.

Types of Hormones Affecting Hair

It’s essential to understand the three main hormones affecting your hair: androgens, thyroid hormones, and estrogens. Together, these hormones regulate the hair growth and renewal cycle, and imbalances in any of them can disrupt this cycle.



Androgens help regulate hair growth by attaching to receptors in the hair follicles. The level of sensitivity of your follicles to these hormones determines your hair growth rate and pattern. If you’ve heard of male or female pattern baldness, you’ve encountered the effects of androgens on hair. An androgen known as dihydrotestosterone, or DHT, is incredibly potent. It shrinks the hair follicles, leading to thinning hair and, eventually, hair loss. While this is most associated with men, all people have androgen hormones in their bodies, meaning anyone can potentially suffer from hair loss.

Thyroid Hormones

The thyroid is a small but mighty gland in the neck that produces hormones responsible for regulating the body’s metabolism, including hair growth. Thyroid hormones regulate the lifecycle of hair follicles, which includes the anagen (growth), catagen (transition), and telogen (resting) phases. Both an underactive thyroid (hypothyroidism) and an overactive thyroid (hyperthyroidism) can lead to hair loss. This is because imbalances in thyroid hormones disrupt the hair growth cycle, generally causing hair to stay in the shedding phase without being replenished as quickly as it should be.


Estrogens contribute to healthy, strong hair growth and can even enhance the growth cycle, leading to thicker, longer hair. Estrogens play a protective role against hair loss. They extend the growth phase of the hair growth cycle, resulting in less shedding. However, an imbalance in estrogen levels, such as during menopause or due to contraceptive use, can overturn this protective effect and lead to increased hair fall. Similar to androgens, everyone naturally possesses estrogens (men included), so anyone can have imbalances in this hormone.


Hormone Imbalances and Hair Loss

Hormonal shifts in the body can easily disrupt hair growth cycles, leading to hair thinning or loss. These fluctuations may be due to various conditions such as pregnancy, menopause, thyroid disorders, or metabolic disorders, among others.

How Hormone Imbalances Disrupt the Hair Growth Cycle

Hormone imbalances can shorten or lengthen the different phases of the hair growth cycle, leading to abnormal hair shedding or decreased hair regeneration. Too much androgen can lead to hair follicles shrinking, thus creating thinner and shorter hair strands. In contrast, insufficient estrogen or thyroid hormones can lead to a shorter growth phase, resulting in hair thinning or even baldness over a prolonged period.

Common Signs of Hormone-Related Hair Loss

Hormone-related hair loss usually occurs evenly across the scalp rather than manifesting in patches like other types of hair loss. Increased hair shedding, thinner hair strands, or a widening part are often the first signs. It’s common to notice hair loss not just on your head but also on other parts of your body, such as your eyebrows or eyelashes.
