Although dandruff commonly colonizes scalp hair, it can also affect the beard. In such cases, it appears as small white flakes that accumulate in the hairs and sometimes fall onto clothing. When oily, these flakes adhere to the face and can cause itching. How can one eliminate beard dandruff? Here are all our recommendations.

The main points to remember.
Beard dandruff is managed in the same way as scalp dandruff.
The anti-dandruff shampoos remain the gold standard for combating dandruff, including that in the beard area.
Some essential oils (tea tree, lavender, Roman chamomile, clove) have demonstrated good antimicrobial efficacy and serve as valuable complements to conventional active ingredients.
The regular exfoliation of the beard enables the removal of flakes and prevents the recurrence of dandruff.

Beard dandruff: are the causes identical to those of scalp dandruff?
Having dandruff in the beard or even in the moustache may be surprising, but this phenomenon is not fundamentally different from that of the scalp. Scales appear when skin cell turnover accelerates or when the yeast Malassezia, which is naturally present on the skin, overgrows. This yeast feeds on the lipids in sebum and can trigger irritation, itching and the formation of small flakes visible in the beard hairs. These may be oily dandruff (white/yellow flakes that adhere to the beard hairs) or dry dandruff (white flakes that fall naturally onto clothing).
Multiple factors promote this proliferation. Sebum production, notably stimulated by testosterone—a male sex hormone—nourishes the yeast Malassezia and exacerbates dandruff issues. External aggressors such as wind, pollution, or cold weaken the skin barrier and can disrupt the cell cycle, thereby increasing the risk of flake formation. Using unsuitable products—too harsh or too rich—or inconsistent cleansing can also contribute to the buildup of dead skin cells and sebum in the beard.
Although the beard is not exactly the same as the scalp, the underlying causes of dandruff remain essentially the same.

Overall, beard dandruff is managed in the same way as scalp dandruff.
It is intended to control fungal proliferation, sebum production, and dead cell buildup on the epidermal surface. There are shampoos specifically formulated for the beard that include anti-dandruff actives, but it is perfectly possible touse regular anti-dandruff shampoos, that is, those originally intended for the scalp. These shampoos can contain various ingredients recognized for their efficacy against dandruff: zinc pyrithione, ketoconazole, the ciclopirox olamine, the piroctone olamine or selenium sulfide. They should be used 2 to 3 times per week, depending on the severity of the dandruff, to effectively reduce flakes. Several clinical studies conducted on the scalp, some of which are presented in the table below, have shown the efficacy of these actives in combating dandruff.
| Study | Participants | Protocol | Results |
|---|---|---|---|
| PIERARD & al (2002) | 150 men affected by dandruff. | Application 2 to 3 times per week for 6 months of a 1% piroctone olamine shampoo, a 1% ketoconazole shampoo, or a 1% zinc pyrithione shampoo. | Itching and dandruff resolve within 2 to 6 weeks after three shampoo treatments. |
| GOODE & al. (2002) | 154 individuals with dandruff, including 70 with seborrheic dermatitis. | Application 3 times a week for 4 weeks a shampoo containing 1.5% ciclopirox olamine plus 3% salicylic acid, or a shampoo containing 2% ketoconazole. | Reduction of 22% in dandruff and 62.5% in seborrheic dermatitis area with ciclopirox olamine and salicylic acid shampoo, compared to a 26% reduction in dandruff and an 80.5% reduction in seborrheic dermatitis area with ketoconazole shampoo. |
| CHO et al. (2003) | 57 subjects with dandruff. | Application of a shampoo containing 1.5% ciclopirox olamine or 2% ketoconazole 3 times per week for 4 weeks. | An 87.5% reduction in dandruff was observed with ciclopirox olamine shampoo, compared to 88.9% with ketoconazole shampoo. |
| SHARIFI-RAD & al (2015) | 30 patients with dandruff. | Application of a shampoo containing 1% piroctone olamine and zinc PCA 3 times per week for 2 months. | Complete elimination of dandruff in 15 patients as early as week 2, in 12 at week 4, and in 3 by the end of week 5. |
Overview of several studies evaluating various anti-dandruff shampoos.

Additionally, certain essential oils can be used for their antifungal and soothing properties. Exercise caution, however: they should not be applied undiluted to the skin, as this may cause irritation. Before using them, dilute them in a carrier oil suitable for your skin type. The essential oils considered as natural treatments for dandruff are those of tea tree, lavender, rosemary and Atlas cedar.
Some scientific studies have evaluated the efficacy of essential oils against the microorganisms responsible for dandruff, specifically Malassezia furfur, Staphylococcus epidermidis and Escherichia coli. A recent study conducted in 2022 determined the minimum inhibitory concentrations of various essential oils to evaluate the appropriate dosages for cosmetic application. The results highlight that certain essential oils, such as tea tree oil, Roman chamomile oil, or clove oil, are effective against M. furfur, the primary agent involved in dandruff, while other oils more specifically target bacteria such as E. coli or S. epidermidis.
| Essential oil | Inhibitory concentration for M. furfur | Inhibitory concentration for E. coli | Inhibitory concentration for S. epidermidis |
|---|---|---|---|
| Tea tree essential oil | 2.0% | 0.5% | 0.5% |
| Roman chamomile essential oil | 0.5% | 1.0% | / |
| Clove bud essential oil | 2.0% | 0.1% | 0.5% |
| True lavender (Lavandula angustifolia) essential oil | / | 1.0% | 1.0% |
| Lime essential oil | / | 1.0% | / |
| Camphor rosemary essential oil | / | 1.0% | / |
| Geranium essential oil | / | 0.1% | 0.5% |
| Palmarosa essential oil | / | 0.5% | 1.0% |
| Peppermint essential oil | / | 1.0% | / |

Note : This data can serve as an interesting starting point for aromatherapy against dandruff. However, avoid blending multiple essential oils in the hope of intensifying their effects, as this can have the opposite result and irritate your skin. Investigate possible synergies in advance and always perform a patch test on a small area of skin before applying an oil more widely.
Another study assessed the efficacy of tea tree essential oil against dandruff. It was a randomized, single-blind trial involving 126 participants with mild to moderate dandruff. Participants used a shampoo containing 5% tea tree essential oil or the same shampoo without the oil daily for 4 weeks. The results showed a significantly greater improvement in the dandruff severity score in the tea tree oil group. Furthermore, statistically significant improvements were also observed in total affected area and itching. No adverse effects were noted, suggesting that 5% tea tree essential oil is both effective and well tolerated for managing dandruff.

Furthermore, it is important to thoroughly cleanse your face each night with a cleanser suitable for your skin type. This helps to remove sebum, impurities, and residues accumulated throughout the day, which can settle in the beard and promote the appearance of dandruff. Additionally, a gentle exfoliation once or twice a week can help eliminate dead skin cells and prevent flakiness. A recent study evaluated the effectiveness of a scalp exfoliation combined with a moisturizing serum in reducing dandruff. The exfoliation included AHAs, BHAs, and PHAs to remove accumulated dead skin cells.
The results demonstrated that after 15 days of daily use, exfoliation using the scrub led to a significant reduction in visible dandruff, with an improvement of more than 60% compared to the start of the study. Simultaneously, scalp hydration was greatly enhanced, helping to reduce dryness and sensation of itchy beard. The study highlights that regular exfoliation, of the scalp or face, helps to remove flakes and prevent keratin buildup, which is an important complement to anti-dandruff shampoos and treatments in managing dandruff.
| Evaluated parameter | Initial value | After 15 days |
|---|---|---|
| Dandruff score | / | Decrease of 61.24% |
| Scalp hydration | / | Increase of 76.24% |
| Proportion of scalp that is dry with an excess of keratin | 65.52% | 6.9% |
| Proportion of normal scalp | 0% | 44.83% |
