Growing a beard is a matter of pride for many men, and the desire for a fuller, thicker beard has led to the popularity of facial hair growth supplements. However, the effectiveness of these supplements is a topic of much discussion. This article explores the science behind beard growth, examines the role of various supplements, and provides practical advice for optimizing facial hair growth.
The Science of Beard Growth
Genetics are the primary determinant of facial hair growth. While it is a common misconception that testosterone levels directly correlate with beard growth, most men have similar testosterone levels. If your father or grandfather struggled to grow facial hair, you may face similar challenges.
Other factors that can affect hair growth include:
- Skin Conditions: Conditions like alopecia can cause hair loss.
- Hypothyroidism: An underactive thyroid, more common in women over 50, can lead to thinning hair.
- Iron Deficiency: Anemia can also cause hair loss.
Lifestyle Factors Affecting Facial Hair
Even with the right genetics, a healthy lifestyle is crucial for optimal hair growth. The following practices can help:
- Reduce Stress: Stress can contribute to hair loss.
- Eat a Healthy Diet: A balanced diet provides essential nutrients.
- Get Plenty of Rest: Adequate sleep supports overall health.
- Don’t Smoke: Smoking can lead to hair loss.
- Take Care of Your Skin: A proper skincare routine can improve hair health.
Supplements for Facial Hair Growth
Many supplements are marketed to promote beard growth, but their effectiveness varies. The Food and Drug Administration (FDA) does not regulate supplements as strictly as prescription drugs, so it’s important to be cautious.

Common Supplements and Their Potential Benefits
- Biotin: Plays a key role in producing keratin, the protein that makes up hair. It may strengthen hair strands, support faster growth, and reduce breakage. Biotin can be easily incorporated into the diet by eating high-protein foods like meat, eggs, and nuts.
- Vitamins: Contain ingredients said to produce thicker, healthier hair. A typical daily vitamin contains similar ingredients and is probably cheaper.
- MSM (Methylsulfonylmethane): A dietary supplement commonly used for inflammation and arthritis. There's no recommended dose of MSM for hair or beard growth.
- Zinc: An essential mineral that helps the body make protein. A dose of 50 mg per day of elemental zinc has been shown to increase hair growth in women with hair loss (alopecia). The human body can't make zinc, so it must be obtained through the diet or as a supplement.
- Vitamin D: Vitamin D deficiency is linked to several forms of alopecia. A 2021 research review suggests that topical vitamin D may be used as a treatment option to regrow hair follicles and prevent miniaturization of follicles in people with AG.
- Protein: Crucial for the production and maintenance of healthy hair. At a minimum, most people need 0.8 grams (g) of protein for every kilogram (kg) of body weight (g/kg) daily.
- Herbs: Some herbs may also help with beard growth, but there isn't much evidence so far.
- Horsetail Extract: This combination product increased hair count and thickness after six months. Of note, horsetail acts as a diuretic.
- Saw Palmetto (Serenoa repens): An herb that's often used for prostate conditions.
Supplements for PCOS Facial Hair
For women dealing with polycystic ovary syndrome (PCOS), facial hair growth can be a significant concern. Several supplements can address the root causes of PCOS-related facial hair:
- Zinc: Zinc is one of the most important supplements for PCOS facial hair.
- NAC (N-Acetyl Cysteine): NAC is a precursor to glutathione, the body’s master antioxidant. A general dose is 500-1000 mg daily.
- Inositols: Naturally occurring compounds that help the body respond to insulin. The 40:1 Myo to D-chiro ratio is consistently shown to be best for PCOS facial hair because it’s the ratio found naturally in the body.
- Vitamin D: Correcting a deficiency can help support ovulation, reduce androgens, and ease symptoms like facial hair.
- Cyprus Rotundus Oil: This oil has a high level of polyphenols that can block androgenic effects on hair follicles.
- Spearmint Tea: Spearmint tea is well-studied and has been shown to significantly reduce circulating androgens that lead to increased facial hair growth in PCOS. Drinking about two cups per day may reduce facial hair growth over time.
The Role of Minoxidil
Minoxidil is a medication originally developed to treat high blood pressure, but it was found to have a side effect of promoting hair growth. It is available in topical and oral forms.
Topical Minoxidil
Topical minoxidil is applied directly to the scalp or beard area. It comes in liquid and foam formulations, with concentrations typically ranging from 2% to 5%.
Advantages:
- Direct application to the desired area.
- Available over-the-counter in many countries.
Disadvantages:
- Can cause dry, flaky skin.
- Requires consistent application.
Oral Minoxidil
Oral minoxidil is taken in pill form and works by increasing blood flow to the hair follicles.
Advantages:
- More convenient than topical minoxidil.
- Can be used in combination with other hair loss treatments.
Disadvantages:
- Potential side effects, such as hypertrichosis (excessive hair growth), headaches, insomnia, or edema (swelling).
- Requires a prescription.
Minoxidil and Facial Hair Growth
Minoxidil’s ability to grow scalp hair has been extensively discussed in the literature, although there has only been one randomized control study presenting its potential for facial hair enhancement. In this report, we will present a case of identical twin males, one of which used topical 5% minoxidil for over a year on the beard and mustache area, while the other abstained from using the medication. As established by observation, the twins were identical/monozygotic twin males with no existing medical conditions. One twin applied approximately 1.5 g (¾ of a cap) of 5% topical minoxidil foam once daily to the beard and mustache area, while the other refrained from using the medication. At the 1 month mark the minoxidil-treated patient noted the presence of new, finer, lighter colored hairs, and by the 2-month mark noted a modest increase in facial hair density. The patient reported shedding of the hairs in the beard area approximately 3 months after initiating minoxidil, but noted that eventually the facial hair growth recovered and continued to progress. Following the conclusion of the shedding phase, facial hair growth continued to advance gradually. (a) Minoxidil treated subject after 16 months of once daily 1.5 g 5% minoxidil foam application. (b) non-minoxidil treated subject. All photos taken at the same time after 10 days of hair growth post-shave.

Important Considerations When Using Minoxidil
- Consult a Healthcare Professional: Before starting minoxidil, consult a doctor to determine the appropriate dosage and assess potential risks.
- Monitor for Side Effects: Be aware of potential side effects and report any concerns to your doctor.
- Combine with Other Treatments: Minoxidil can be used in combination with other treatments, such as finasteride or microneedling, to enhance its effectiveness.
Surgical Options for Facial Hair Restoration
For those who have lost their beards due to trauma, surgical treatments are available. Follicular Unit Extraction (FUE) is one method used to reconstruct beard loss.
The Importance of Personalized Treatment Plans
There is no one-size-fits-all solution for hair loss or facial hair growth. Each person’s case is unique and requires a personalized treatment plan tailored to their specific needs and goals. Consulting with a dermatologist or healthcare professional is essential for creating a comprehensive plan that addresses short-term and long-term hair restoration.
Optimizing Beard Growth: A Comprehensive Approach
To optimize beard growth, consider the following strategies:
- Maintain a Healthy Lifestyle: Eat a balanced diet, get enough sleep, and manage stress.
- Use Appropriate Skincare: Cleanse and moisturize your face daily.
- Consider Supplements: Evaluate the potential benefits of supplements like biotin, zinc, and vitamin D.
- Explore Minoxidil: Consult with a healthcare professional to determine if minoxidil is a suitable option.
- Be Patient: Hair growth takes time, so be patient and consistent with your chosen methods.
