Why Do Men’s Eyebrows Get Bushy With Age?

When hair elsewhere is disappearing why do men’s eyebrows get bushy with age? We have eyebrows to keep sweat from going in our eyes. Not only do they play a functional part in life, but they also add to our facial appearance.

Differences for Men and Women.

Changes in eyebrows tend to differ for women and men as we age. For women, our eyebrows stop growing as we age. Our eyebrow hairs become longer but they become sparse. However, for men it’s the opposite! As they age most men find  their eyebrows have suddenly taken on a new lease of life and grown bushy and out of control!

Hormonal Changes

For men, the growth of their eyebrows is due to hormonal changes. For many their levels of testosterone remain consistent or continue to increase until the age of 70. This often results in vigorous hair growth, especially for eyebrows and ear hairs.


Dihydrotestosterone (DHT)is a biologically active metabolite of the hormone testosterone. It is formed primarily in the prostate gland, testes, hair follicles, and adrenal glands. This hormone belongs to a class of compounds known as androgens. These hormones are also commonly called androgenic hormones or testoids.

They are part of the biology of gender, stimulating and controlling the development and maintenance of masculine characteristics. DHT is 3 times more potent than testosterone produced by males and is responsible for the formation of male sex-specific characteristics. It is an important contributor to other characteristics generally attributed to being a man. These features include facial and body hair growth, and deepening of the voice. DHT is also the primary contributing factor in male-pattern baldness when men prematurely lose their hair.

Taming bushy eyebrows

Nowadays male grooming is a big business. There are multitudes of clinics where men can have their eyebrows professionally trimmed shaped, and even dyed.

There are special eyebrow trimming sets  that can be used at home and many hairdressers offer to trim trim eyebrows along with their haircut.

  1. I am a 60 year old woman and I have Grandpa brows. Not big and bushy like caterpillars but several random stray hairs do grow extra long and in odd directions. This has been happening for about the last five or six years. I’m sure it is a hormonal thing. Just wanted you to know it’s not just men.

  2. Thank you so much for your expert comment on my post, I really found it interesting and admit as the author I lack the knowledge you obviously have. I shall leave your comment for other readers as I am sure they will also be interested.

  3. the author apparently didnt check from all angles before posting this article which might mislead folks.

    Yes, the hair growth has something to do with testosterone, but it is proportional to the sensitivity of individual’s skin follicles.

    For example, with same amount of testosterone level, the man with low senstitivity skin follicles are hairy, while the ones with high sensitiviity are not.

    For some people, age will alter the sensitivity of the skin follicles, that’s why some folks get hairier when they grow old despite the testosterone has decrease to little.
