What Causes Sparse Beard and Eyebrows?
Beard density is largely determined by genetic makeup and the sensitivity of hair follicles to male hormones. For this reason, in some people the beard comes in late or stays sparse and patchy. Hormonal deficiencies, thyroid disease, and iron and vitamin deficiencies can also affect beard and eyebrow density.
Thinning of the eyebrows can be related to frequent plucking or tweezing, age-related changes and an underactive thyroid gland; loss in the outer part of the eyebrow in particular raises the question of a thyroid evaluation. Round, patchy hair loss can be related to alopecia areata and is addressed separately.
In the beard area, alopecia areata often appears as round, hairless patches with clear borders that appear suddenly. In this case the treatment approach differs from genetic sparseness and, if needed, is planned together with a dermatologist.
Who Is It Suitable For?
- Men whose beard grows sparse, patchy or with gaps
- Young adults whose beard growth is delayed
- Those whose eyebrows have thinned after frequent plucking or tweezing
- Those who notice new hair loss in the eyebrows or beard
- Those who want to support areas other than the scalp before considering a beard or eyebrow transplant
In women, sparse eyebrows can also be related to hormonal changes during menopause; in that case, overall hair and skin health are evaluated together.
How Is the Treatment Planned?
- A history is taken and the area is examined; whether the sparseness is genetic or has developed later is assessed.
- If needed, thyroid, hormone, iron and vitamin tests are requested.
- Any deficiencies found and underlying conditions are treated.
- In suitable people, mesotherapy or PRP sessions are planned for the beard or eyebrow area.
- Topical treatments may be added on the doctor’s advice; in selected people who do not get an adequate response, a transplant option can be discussed.
Although topical minoxidil is widely used on the beard area, this use is outside the medication’s approved indications; it should therefore be considered only on a doctor’s advice and with follow-up, after discussing possible side effects.
What Should You Keep in Mind Afterward?
- Do not shave, wax or tweeze the area on the first day after the procedure.
- Do not rub the area for the first 24 hours, and do not use makeup or cosmetic products.
- Excessive eyebrow plucking and frequent tweezing should be avoided.
- Recommended topical products should be used regularly.
- Be patient for at least a few months to assess the result.
Possible Side Effects and Who Should Not Have It
Redness, mild swelling, tenderness and, rarely, bruising may occur after injections. Topical treatments may cause dryness, itching or irritation of the skin; these products should be used on a doctor’s advice and at an appropriate dose.
The procedure is not performed, or is postponed, during pregnancy and breastfeeding, if there is an active infection, acne or wound in the treatment area, in bleeding disorders and with the use of blood-thinning medication.
Dr. Fulya Koç’s Approach
For sparse beard and eyebrows, Dr. Fulya Koç first investigates treatable causes, above all thyroid and hormonal status. Where genetic makeup is the deciding factor, she openly shares realistic expectations and aims for a natural result in harmony with the person’s facial expression.
Because eyebrows are an important part of facial expression, the person’s natural eyebrow structure and facial proportions are taken into account when eyebrows are sparse. The aim is not a marked change, but a balanced look that preserves the person’s own expression.

Frequently asked questions
A beard that does not grow or stays sparse is most often related to genetic makeup. In some cases hormonal problems such as low testosterone, thyroid disease or nutritional deficiencies may also play a role; for this reason, tests are done if needed.
They may help strengthen existing but thin and weak hairs. New beard growth is not expected in areas with no hair follicles. The response varies from person to person.
Thinning in the outer third of the eyebrow can be related to an underactive thyroid gland. If this finding is present, an evaluation with thyroid function tests is recommended.
