Aging – Prostaglandin is the hormone that signals your eyebrows to grow. As we get older, our natural prostaglandin production declines. That's why it's common around menopause for our eyebrows to thin, grow a little longer, become coarse and even change color.
Hair loss during the menopause is the result of hormonal imbalances in the body. The decreased production of oestrogen and progesterone can result in hair growing more slowly and becoming thinner. Unfortunately, these hormones can play havoc with our brows but works wonders for producing hairs on our chin instead.
Eyebrows start to look sparse due to the natural decline of testosterone (in men) and estrogen (in women) that begins in the 40s. Both of these hormones affect the hair growth cycle and the structure of the hair follicles.
Maintaining a balanced diet goes a long way on the journey to achieving thicker eyebrows. Eating foods that are rich in biotin, omega 3 fatty acids, and vitamins A, B, C, D, and E can speed up the eyebrow growth process more than you know.
As the follicles grow more sensitive to androgens, the hormones keep them in the anagen phase longer, leading to more hair growth with age in places such as the eyebrows, nose and ears.
"The only way to thicken brows naturally is to stop tweezing, waxing, and threading, and let them grow," says New York-based makeup artist and global eyebrow expert Maribeth Madron. While this may seem simple enough, it can be tempting to tweeze one hair here and one hair there.
As we age, our prolonged exposure to testosterone starts to play a visible role on other body hair as well. Just like it transforms the vellus hair on a young man's face into a thick beard, it also changes the nearly invisible hair that grows in places like our ears into thicker strands.
Brows grow in a three to four month cycle, so you should avoid plucking any hairs until at least 12 weeks have passed. After then, you can pluck the ones that aren't anywhere near your brow line, but leave any that are close to that area alone. Try to groom your brows daily with a brush, too.
Bimatoprost (brand name Latisse®) is a prescription topical used to lengthen and thicken eyelashes. “It's been shown to help brows, too,” says Dr. Khetarpal. If you prefer the over-the-counter route, try 2% or 5% minoxidil (brand name Rogaine®).
Hormonal imbalances
An imbalance of thyroid hormones can cause eyebrow hair to fall out. This is linked to the following conditions: hyperthyroidism, a condition wherein the body creates too much thyroid hormone. hypothyroidism, in which the body does not create enough thyroid hormone.
Thinning Eyebrows Due to Nutrient Deficiencies
Nutrient deficiencies that can contribute to hair loss include: Vitamin A, C, E, B-7 (Biotin), B-12, and D. Zinc. Iron.
Nutritional deficiencies can affect hair, and make it thin or make it fall out. For example, a deficiency in zinc, iron, or biotin can make you lose your eyelashes or eyebrows.
Most of the time, eyebrows do grow back, but how fast they grow will depend on your age and overall health. A little patience, avoiding plucking and waxing, and changing your diet may be all you need.
Brow pencils, powders, and gels can help you achieve a brow look you love. You can use these products to define the arch in your brow, fill in sparse areas, and make your eyebrows appear fuller than they really are.
As we get older, our hair follicles slow down and stop producing new hairs, which nobody can control. Genetics, hormones and age will impact how fast your eyebrows grow back, and a balanced diet can help in this regard. You should also avoid plucking, waxing and threading to give your eyebrow hair the chance to grow.
Good eyebrows, ones that add structure and definition to our faces, can be attained at any age. The problem for many of us at 50+ is that we went a bit crazy back in the day with eyebrow plucking. But not to worry, dear readers, over-plucked (or over-waxed) brows can be fixed.
For women, the hair may grow in areas where men often have a lot of hair, but women often don't. This includes the upper lip, chin, chest, and back. It's caused by an excess of male hormones called androgens. All women naturally produce small amounts of androgens.
Hair growth and size is modulated by hormones, in particular androgens like testosterone, which kick in during puberty. As men generally have higher levels of testosterone than women they tend to have more terminal hair.
The discovery of the odd hair on your chin is perfectly normal and usually not a cause for concern. Shifting hormones, aging, and even genetics could be behind a few chin hairs that stand out. For that, there are simple and efficient ways to remove them if you don't want them.

“As we get older, the natural aging process thins the hairs on our bodies,” says Tonya Crooks, a celebrity brow expert and founder of The BrowGal. Consequently, sparse eyebrows are a sign of that aspect of the aging process—just like the thinning of hair on your head.
If your diet is lacking in vitamins or nutrients that are key for a healthy diet, then this could be a contributor to your lack of hair growth in your eyebrows. Try to keep your diet rich in Vitamin B, omega-3s, iron, protein and zinc. Also ensure that your water intake is high so that your hair growth is optimum.
