The scalp, while often overlooked, plays a vital role in our overall health and appearance. Covering the top of the skull and housing thousands of hair follicles, it serves as a barrier, protecting the head and supporting hair growth. However, various scalp diseases can develop silently, causing discomfort, hair loss, or long-term damage if left untreated.
Here’s a guide to common scalp diseases you may unknowingly have and how to fight them effectively.
Seborrheic dermatitis
What it is:
Seborrheic dermatitis is a common skin condition that causes flaky, scaly patches on the scalp. It is related to an overgrowth of yeast (Malassezia) on the skin, combined with inflammation.
Symptoms:
Persistent dandruff (yellow or white flakes)
Itchy scalp
Red, greasy patches on the scalp
Hair thinning (in severe cases)
How to fight it:
Treatment: Use medicated shampoos containing ingredients like ketoconazole, selenium sulfide, or zinc pyrithione. Prescription creams or antifungal medications may be needed for severe cases.
Prevention: Wash your hair regularly and manage stress, as stress can worsen symptoms. Avoid harsh hair products that can irritate the scalp.
Scalp psoriasis
What it is:
Psoriasis is an autoimmune condition that causes skin cells to build up rapidly, leading to thick, scaly patches. Scalp psoriasis is a common manifestation and can range from mild to severe.
Symptoms:
Thick, silvery scales on the scalp
Itchy, dry patches that may bleed when scratched
Temporary hair loss (due to irritation)
How to fight it:
Treatment: Use medicated shampoos with salicylic acid or coal tar. Topical steroids, vitamin D analogs, or biologic therapies may be prescribed for severe cases.
Prevention: Keep the scalp moisturized and avoid triggers like stress, smoking, and alcohol.
Folliculitis
What it is:
Folliculitis is the inflammation or infection of hair follicles, often caused by bacteria, fungi, or blocked follicles. It can lead to scalp irritation and, in some cases, permanent hair loss.
Symptoms:
Red bumps or pustules around hair follicles
Itchy or tender scalp
Crusting or scabbing in severe cases
How to fight it:
Treatment: Mild cases can be treated with antibacterial shampoos or topical creams. For more severe infections, oral antibiotics or antifungals may be required.
Prevention: Avoid tight hairstyles, keep your scalp clean, and avoid sharing hats or brushes.
Tinea capitis (scalp ringworm)
What it is:
Tinea capitis is a contagious fungal infection that primarily affects children but can occur in adults too. It’s caused by dermatophyte fungi and spreads through direct contact or shared personal items.
Symptoms:
Round, scaly patches on the scalp
Hair breakage, leaving bald spots
Itching and redness
Swollen lymph nodes (in severe cases)
How to fight it:
Treatment: Oral antifungal medications like terbinafine or griseofulvin are necessary. Antifungal shampoos may also be recommended to prevent the spread.
Prevention: Avoid sharing combs, hats, or pillows, and wash them regularly.
Alopecia areata
What it is:
Alopecia areata is an autoimmune condition where the immune system attacks hair follicles, leading to patchy hair loss. The exact cause is unclear, but genetics and stress may play a role.
Symptoms:
Round or oval bald patches on the scalp
Smooth, hairless skin in affected areas
Potential nail changes (ridges or pitting)
How to fight it:
Treatment: Corticosteroid injections, topical minoxidil, or immunotherapy can help stimulate hair regrowth. In some cases, oral medications may be necessary.
Prevention: While it cannot be entirely prevented, reducing stress and maintaining a healthy immune system may lower the risk of flare-ups.
Lichen planopilaris
What it is:
Lichen planopilaris is a rare inflammatory condition that causes permanent scarring and hair loss by damaging hair follicles.
Symptoms:
Redness and scaling around hair follicles
Burning or itching sensation on the scalp
Irregular hair loss with scarring
How to fight it:
Treatment: Anti-inflammatory medications like corticosteroids or immunosuppressants may be prescribed. Early treatment is critical to prevent further hair loss.
Prevention: Since the cause is not fully understood, regular scalp check-ups can help catch the condition early.
Traction alopecia
What it is:
Traction alopecia occurs due to prolonged tension on hair follicles, often caused by tight hairstyles or extensions.
Symptoms:
Gradual hair thinning or baldness along the hairline
Tenderness or soreness on the scalp
Broken hair strands
How to fight it:
Treatment: Loosen hairstyles to relieve tension on hair follicles. Topical minoxidil can encourage regrowth. In severe cases, hair transplant surgery may be considered.
Prevention: Avoid tight braids, ponytails, or extensions. Opt for natural hairstyles that don’t pull on the scalp.
Scalp eczema
What it is:
Scalp eczema, or atopic dermatitis, is a chronic condition that causes inflammation and irritation of the skin.
Symptoms:
Itchy, red patches on the scalp
Dry, flaky skin that may resemble dandruff
Crusting or oozing in severe cases
How to fight it:
Treatment: Use gentle, hypoallergenic shampoos and moisturizers. For severe cases, corticosteroid creams or antihistamines may be recommended.
Prevention: Avoid harsh hair products and identify triggers, such as certain foods or allergens.
General tips for scalp health
Practice good hygiene: Wash your hair regularly to prevent buildup of oil, dirt, and dead skin.
Use gentle products: Avoid shampoos or treatments with harsh chemicals that can irritate the scalp.
Maintain a balanced diet: Nutrients like biotin, zinc, and omega-3 fatty acids support scalp and hair health.
Stay hydrated: Keeping your body hydrated helps prevent dry, flaky skin.
Limit heat and styling: Excessive heat and tight hairstyles can damage hair and irritate the scalp.
Visit a dermatologist: If you notice unusual symptoms like persistent itching, redness, or hair loss, seek professional advice early.
Conclusion
Scalp diseases are more common than many people realize, and their symptoms are often mistaken for minor issues. Left untreated, these conditions can lead to discomfort, infections, or even permanent hair loss. By understanding potential scalp issues and adopting a proactive approach to scalp care, you can protect both your hair and your overall health. Don’t ignore your scalp—it’s as important as the rest of your body!
