Minoxidil For Eyebrows – Does It Work?

Key Takeaways:

• What is the evidence for minoxidil for eyebrow loss? Studies have shown that consistent minoxidil use can help to improve eyebrow thickness and density. 
  
• Do I need a prescription to take it? Minoxidil, a hair loss medication which is commonly sold under the brand name Regaine, can be purchased over the counter at your pharmacy. As such, it is not necessary to get a prescription before using it.
  
• Who is it unsuitable for? It’s best to avoid taking minoxidil for your eyebrow loss if you believe there is an underlying condition causing the loss that needs to be treated first, or you have visible inflammation, redness, or infection of the eyebrows. 
  
• What precautions are there to take? Your eyebrows are in a delicate part of the face close to important structures, like the eyes. You need to apply the minoxidil carefully and follow precise application tips to avoid causing damage to your vision

Eyebrows are a hugely important feature in humans for communication, facial expression, and identity. They serve a clear social and practical purpose. When your eyebrows are thinning, this can have a detrimental impact on your self-confidence and ability to express yourself.

What Is Minoxidil, and Is It Approved for Eyebrows?

Minoxidil is a hair growth medication that is most commonly applied to the scalp to help with pattern hair loss. It’s not currently licensed for eyebrow growth. 

For eyebrow loss, it is used off-label. This doesn’t mean it is unsafe or ineffective, just that more care needs to be taken when weighing up the decision to take it for any other purpose than it was originally intended.¹ In this case, it is not too difficult to see why a hair growth medicine applied to the scalp could not equally show benefits for growing your eyebrow hair.

Why Are My Eyebrows Thinning?

Eyebrow thinning (eyebrow madarosis in medical terms) is a symptom and not a diagnosis in itself. Much like scalp hair, eyebrow hair loss can have many different causes and can be scarring or non-scarring. Scarring types of hair loss are often permanent as a result of damage to the follicle by deep inflammation. 

Possible causes of your eyebrow thinning include:

Natural or age-related thinning. Eyebrow hairs tend to become finer, shorter, or less dense over time. This is a natural progression and is not linked to disease.

Previous overplucking or repeated trauma. Persistent plucking, rubbing, or pulling at your eyebrows can interrupt their growth and may even cause lasting damage.

Autoimmune: Some autoimmune types of hair loss, such as alopecia areata, can cause a loss of eyebrow hair after the body recognises the hair follicles as a foreign body and targets them for attack.

Thyroid or nutritional problems. Thyroid disease and deficiencies involving nutrients such as iron or zinc can contribute to hair loss.

Scarring hair loss. Inflammatory conditions such as frontal fibrosing alopecia can affect the eyebrows alongside scalp changes. 

Medication or medical treatment. Chemotherapy, radiotherapy, and certain medicines can change the hair cycle and make hair as well as eyebrow hair fall out. 

Does Minoxidil Work for Eyebrows?

The current evidence shows that minoxidil helps regrow eyebrow hair and increase eyebrow density.^2,3  However, it must be noted that these studies were short in duration, but they are clear in the positive use case of minoxidil for eyebrows. 

Whether minoxidil will work for you will also depend on the type of hair loss, whether your eyebrow hair loss is scarring or non-scarring. Minoxidil will not work on hair loss due to scarring.⁴

How Does Minoxidil Help Eyebrow Hair Grow?

Minoxidil works by influencing the hair cycle of hair follicles; its effect is not specific to scalp hair. It increases blood flow to the hair follicles and encourages resting hair follicles to enter an active state of hair growth.

It also maximises the amount of time hairs spend in this active phase of growth, which is beneficial when looking to treat eyebrow hair loss. One thing to consider is that Minoxidil can only work with existing hair follicles; it can not make new follicles; therefore, a response will depend on you having functioning and healthy follicles remaining in the thinning area.

Who May, or May Not Be Suitable for Minoxidil?

Your suitability for minoxidil treatment depends on the reason your eyebrow hair has become sparse. Your doctor will examine the skin and hairs closely, review your health record and medication history, and try to piece together the cause of your eyebrow loss.

It may be considered for:

• Naturally sparse eyebrows
  
• Gradually thinning eyebrows with normal, healthy skin
  
• Non-scarring eyebrow hair loss
  
• Thinning associated with previous overplucking, provided the follicles remain undamaged.

Even if you meet one of the criteria above, this doesn’t mean you are guaranteed to see eyebrow growth. Your individual response will be unknown until it is trialled.

Seek professional advice before using minoxidil if:

• Your eyebrow loss is sudden, patchy or unexplained
  
• The skin is red, scaly, infected or irritated
  
• You have heart disease, an abnormal heart rhythm, blood pressure problems or a circulation disorder
  
• You are pregnant, trying to conceive or breastfeeding
  
• You take other medicines
  
• You use prescription, cosmetic or ophthalmic treatments around the eyes
  
• You have also lost scalp or other body hair

Minoxidil should not be used in pregnancy or breastfeeding because trials have shown a risk of harm to a developing foetus.⁵

How Should Minoxidil Be Used on Eyebrows?

Minoxidil (brand name Regaine) comes in two strengths, 2% and 5%. The skin around your eyebrows is delicate. For this reason, we recommend you start at the lower 2% formulation and see how you get on. If you notice that you tolerate it well without any side effects, then you may wish to move to the 5% formulation.

With minoxidil, ensuring proper application matters more than absolute saturation of the product. Apply it with a small cotton swab or other small applicator directly onto your brow hair. It will need to be applied consistently every day for you to see the full benefits.

Here are some practical application tips:

• Apply it only to clean, dry, and unbroken skin
  
• Use an extended spray-tip precise applicator rather than allowing drops or foam to spread
  
• Keep the product in the intended eyebrow area
  
• Avoid the eyelids, eyes, and surrounding facial skin
  
• Wash your hands immediately after applying it
  
• Let the area dry fully before touching it, applying cosmetics, or going to bed
  
• Do not increase the quantity or frequency in order to speed up growth; results will take time

Applying more than necessary doesn’t mean you will get faster or fuller results. What it does, however, is increase the local irritation and potential for side effects.⁵

How Long Does Minoxidil Take to Work on Eyebrows?

Change is a gradual process. Expect it to take 6 -12 months before you see noticeable progress. Prepare for the fact that the response may be subtle: slightly more hairs, thicker hairs, or fewer visibly sparse patches on your eyebrows, rather than a complete renewal of your eyebrows.

The best way for you to measure results is to take photographs before treatment and at consistent intervals throughout treatment. Use the same lighting, camera distance, camera angle, and brow grooming each time. Otherwise, you might mistake shadows or differences in makeup as growth. 

Much the same as minoxidil for your scalp,  you may notice an initial increase in shedding of eyebrow hair after you begin treatment. This is an expected and well documented effect of using minoxidil and isn’t a sign that the treatment is a failure. Keep applying the minoxidil, as the results require patience.

What Are the Side Effects?

The skin around the eyes is thin and sensitive. Even a small amount of misplaced product can cause a huge amount of discomfort. 

Possible side effects are:

• Redness, itching, dryness, or burning.
  
• Rash or contact dermatitis
  
• Unwanted hair growth beyond the eyebrow
  
• Eye itching or irritation
  
• Headache
  
• Dizziness
  
• Palpitations, a faster heartbeat, or low blood pressure
  
• Chest pain, faintness, swelling, or unexplained weight gain.

Most of the side effects, if any, you will experience will be mild and around the site where you apply it. Stop using it if the irritation is severe, persistent, or spreading. If minoxidil enters an eye, rinse it out thoroughly with plenty of cool water. 

Seek immediate medical help by calling 999 or attending A&E if you develop:

• Chest pain
  
• Fainting
  
• Breathing difficulty
  
• Marked swelling of the hands, face or feet
  
• Signs of a severe allergic reaction

What Are the Alternatives to Minoxidil?

The main alternatives for you to consider aside from minoxidil are:

Cosmetic camouflage

Brow pencils, powders, and tinting can improve eyebrow definition without stimulating follicles. Microblading (a semi permanent tattooing of the eyebrows) can also be considered if your skin is otherwise healthy.

Eyebrow hair transplantation

Surgery may be a great option for people who have permanent yet stable eyebrow hair loss. It can help them bring back their usual expressive eyebrows and help them with confidence and communication.

Can I Have an Eyebrow Transplant?

An eyebrow transplant can be considered if the underlying cause of the hair loss has been uncovered and the hair loss has remained stable for a suitable amount of time. 

“We can perform eyebrow hair transplant surgery in patients with stable eyebrow hair loss or overplucked eyebrows. It can help restore hair where it was once there, reshaping or rebuilding lost density. At our clinic we are experts in being able to perform long hair eyebrow transplantation, transferring long hair follicles into the eyebrows for immediate visual results.”

Dr Roshan Vara, Co-Founder and Hair Transplant Surgeon at The Treatment Rooms London

Diagnosis always comes before surgery, as certain inflammatory conditions can go on to destroy transplanted hair follicles, making the whole procedure futile. A specialist may require you to have medical treatment or a period of observation before a transplant is considered. 

As transplanted scalp hairs still keep many of their original characteristics, they will grow longer than natural eyebrow hairs and require regular trimming.⁶

Conclusion

Minoxidil can improve eyebrow density and thickness for some people, particularly when the loss is non-scarring and viable hair follicles remain. 

The most useful next step is to establish why your eyebrows are thinning. This will help to decide on a treatment plan for your eyebrows that offers the best balance of benefit and risk and allows you to regain your full natural expressive ability.
