Dandruff and Dreadlocks: Causes, Treatment, and Management

Dandruff is a common scalp condition characterized by flaking skin and itching. Nearly 50% of the global population will experience dandruff at least once in their lives. While dandruff is not inherently harmful, it can be particularly troublesome for individuals with dreadlocks (locs), as the flakes can become trapped within the strands, making them more noticeable. Maintaining scalp health is fundamental when caring for locs, and understanding the causes and treatments for dandruff is crucial for those with this hairstyle.

Understanding Dandruff

Dandruff is a scalp condition that causes flakes of skin to appear. It may also be accompanied by itching. While it can occur at any age, it is more common from the teenage years up to midlife. Poor hygiene is not a direct cause of dandruff, but infrequent washing or brushing can make the flakes more visible.

Causes of Dandruff

Several conditions can contribute to dandruff:

• Dry Skin: Dry skin can lead to flaking and irritation of the scalp.
• Seborrheic Dermatitis: This condition causes irritated, oily skin and is strongly associated with dandruff. The skin becomes red, greasy, and covered with flaky white or yellow scales. Seborrheic dermatitis can affect not only the scalp but also the backs of the ears, eyebrows, chest, and other parts of the body. An overreaction to Malassezia, a yeast that occurs on the scalp, is among the causes of seborrheic dermatitis.
• Sensitivity to Hair Products: Certain hair care products can irritate the scalp and lead to dandruff.
• Malassezia Overgrowth: This fungus commonly lives on the scalp and feeds on the oils secreted by hair follicles. In some people, the immune system overreacts to Malassezia, causing the scalp to become irritated and produce extra skin cells. As these extra skin cells die and fall off, they mix with the oil from the hair and scalp to form dandruff.
• Other Skin Conditions: Conditions like eczema, psoriasis, and ringworm can also cause flaking skin on the scalp.

Factors Increasing the Risk of Dandruff

Various factors can increase the risk of developing dandruff:

• Age: Dandruff is more likely to occur between the teenage years and midlife. Cradle cap, a type of dandruff, is also common in babies.
• Weather: Temperature extremes, especially a combination of cold weather and overheated rooms, can contribute to dandruff.
• Stress: High stress levels can worsen symptoms of seborrheic dermatitis, such as dryness and itching. A 2023 cross-sectional study of 629 questionnaires found that the general population of Saudi Arabia associated stress with skin conditions such as hair loss, eczema, and acne.
• Medical Conditions: Certain medical conditions, such as psoriasis, HIV, acne, rosacea, Parkinson’s disease, epilepsy, alcohol dependency, depression, eating disorders, recovery from a stroke or heart attack, a weak immune system, fatigue, and obesity, are associated with a higher likelihood of seborrheic dermatitis and, consequently, dandruff. One study has found that 30-83% of people with HIV have seborrheic dermatitis, compared with 3-5% of the general population.
• Hormonal Factors: Dandruff is more common in males, suggesting that hormonal factors may play a role.
• Diet: Dietary deficiencies in nutrients like zinc and B vitamins may contribute to dandruff.

Managing Dandruff in Dreadlocks

Managing dandruff in locs requires a consistent and careful approach to ensure the scalp remains healthy without damaging the locs.

Cleansing Routine

Maintaining a regular cleansing routine is essential. Use a gentle, sulfate-free shampoo designed to treat dandruff without stripping your locs of their natural oils. Shampoos with ingredients such as ketoconazole, coal tar, and salicylic acid can be effective.

Natural Remedies

Several natural remedies may help manage dandruff:

• Tea Tree Oil: Tea tree oil has antifungal and antibacterial properties. It may irritate sensitive skin, so it is best to dilute it by adding a few drops to a carrier oil such as jojoba or coconut oil before applying it directly to your skin. A 2020 study found that applying placental tissue soaked in tea tree oil was more effective than a prescription antifungal treatment for healing lesions caused by the fungus Malassezia.
• Coconut Oil: Coconut oil may improve skin hydration, skin barrier function and protection, and decrease inflammation. Test-tube studies also suggest coconut oil and its compounds may have antimicrobial properties. In a 16-week study of 140 women, applying coconut oil to the scalp improved the scalp microbiome and certain markers of dandruff.
• Apple Cider Vinegar (ACV): ACV is acidic, which may reduce dryness on your scalp. It may also balance the pH of your skin to reduce fungal growth and fight dandruff. However, a 2022 study found that applying diluted ACV topically to the skin didn’t improve eczema or skin barrier integrity and even worsened skin irritation. To try using ACV, add a few tablespoons to your shampoo or combine it with just a few drops of essential oils and spray directly onto your hair.
• Crushed Aspirin: Aspirin contains salicylic acid (SA), which has anti-inflammatory properties and can help get rid of scaly skin and loosen flakes. A small 2018 study showed that a shampoo containing SA significantly improved irritation and itching in 10 people with scalp inflammation. Try crushing two aspirin tablets and adding the powder to your shampoo before washing your hair.
• Probiotics: Probiotics may enhance immune function, which may help your body fight the fungal infections that cause dandruff. A 2017 study suggests that taking probiotics for 56 days significantly reduced dandruff severity in 60 people. Probiotics may also help treat and prevent skin conditions such as eczema and atopic dermatitis, especially in infants and children.
• Baking Soda: Baking soda may act as a gentle exfoliant to help remove dead skin cells and reduce scaling and itchiness. It may also have antifungal properties. A 2024 analysis found that baking soda improved dandruff symptoms in people without the harmful side effects of systemic antifungal treatment. To use, apply baking soda directly to wet hair, massage it into your scalp, let it sit for 1 to 2 minutes, and then continue shampooing your hair as usual.

Maintaining Overall Scalp Health

In addition to specific treatments, maintaining overall scalp health is key:

• Moisturize: Ensure your locs and scalp are adequately moisturized. Dryness can worsen both dandruff and psoriasis, so incorporating natural oils such as jojoba, coconut, or olive oil can be very beneficial.
• Stress Management: Stress can trigger or worsen scalp conditions, so integrating stress-relief practices into your routine can have a positive impact on your scalp health.
• Balanced Diet: Consume a balanced diet rich in vitamins and minerals, particularly those that promote skin health like vitamins A, D, and E, to support your scalp and locs.
• Avoid Irritants: Stop using any products that are suspected of causing irritation and switch to hypoallergenic or gentle formulations.

Medical Treatments

If home remedies and over-the-counter products don’t help, consult a doctor. They may prescribe topical antifungal medications, corticosteroids, or immunomodulators to treat dandruff and other skin conditions. Shampoos with ingredients such as zinc pyrithione, selenium sulfide, ketoconazole, coal tar, salicylic acid, and sulfur can also be effective.

When to Seek Medical Advice

If dandruff and itching are severe and persistent, or if symptoms worsen, it may be a good idea to see a doctor. They may identify an underlying problem that will respond to a specific treatment. People should seek medical help if:

• There are signs of infection, such as redness, tenderness, or swelling.
• The dandruff is severe, and home treatment does not help.
• There are signs of eczema, psoriasis, or another skin condition.
• The scalp is very itchy.

Dandruff vs. Psoriasis

It's important to differentiate between dandruff and psoriasis, as psoriasis requires a more targeted approach. Psoriasis is a more severe condition that causes thick, red, scaly patches on the scalp. Medicated shampoos containing salicylic acid or coal tar can be very effective in managing symptoms. Given the complexity of treating psoriasis with locs, it might be best to consult a trichologist or dermatologist for personalized advice and possible treatments.

Additional Considerations

• Switch Shampoos: A specific shampoo may become less effective over time. A person who feels their choice is losing its effectiveness may want to switch to a different shampoo with another ingredient.
• How to Use Shampoo: Follow the instructions on the container for how long to leave a product on the scalp.
• Frequency of Shampooing: For Black people, shampoo once a week with a dandruff shampoo. Ask a dermatologist to recommend a suitable option. For white and Asian people, shampoo daily, and use a dandruff shampoo twice a week. If one shampoo does not help, try another one.

Research and Future Treatments

Research into ways to help people with dandruff is ongoing. Infusions of green, black, or white tea may help prevent dandruff and improve the condition of a person’s hair and scalp. Experts say this may be due to the antioxidants tea contains or other properties that offer protection from sunlight.
