Doesn’t it embarrass you to brush off dandruff from your hair and shoulders all the time? Are you experiencing hair loss since your dandruff started? Dandruff is not a problem related to your hair but is the problem of the skin of your scalp. The dead skin cells that buildup on your scalp are responsible for causing these white flakes called “dandruff”. Dandruff is neither contagious nor a serious problem. It can be controlled by following simple home remedies and taking over-the-counter medications.

WHAT IS DANDRUFF?

Dandruff is a common skin condition that causes dry and white or grey flakes to appear on the scalp and hair. It is often accompanied with itching. Sometimes, severe dandruff may result in inflammation of the scalp skin.

Dandruff is a less severe form of seborrheic dermatitisor seborrhea. Seborrhea can affect different areas like ears, eyebrows, eyelids, crease of the nose, back of the neck, armpits, groin, and bellybutton. It can occur in both men and women irrespective of age. In babies, seborrheic dermatitis is characterized by greasy, yellowish crusts on scalp, eyebrows and nappy area, which is called as ‘cradle cap’.

CAUSES

The exact cause of dandruff is unknown. However, research suggests the following reasons for dandruff:

  • Overproduction of sebum (skin oil) in the hair follicles

  • Growth of fungus called ‘malassezia’ in the scalp

  • Abnormalities in hormone levels during teenage

  • Dry skin caused by weather, mainly winter season

  • Other skin conditions, such as psoriasis, eczema and acne

  • Too much or not enough shampooing

  • Sensitivity to hair-care products or hair dye

ASSOCIATED SYMPTOMS

The other symptoms that accompany dandruff commonly include:

  • Itchy scalp or skin

  • Dry and flaky skin in other body parts, such asears, eyebrows, eyelids, forehead, beard or moustache, chest, etc.

  • Hair fall

DIAGNOSIS

Your doctor may diagnose your dandruff by looking at your scalp or hair. If required, he may take a small sample of your scalp skinor send a small sample to a lab to check for any scalp related disorders (scalp biopsy). Usually, it is not necessary to consult your doctor for dandruff, as many over-the-counter products are available for treating dandruff. But, it is recommended to consult if you have severe dandruff or any serious problems like inflammation and oozing fluid or blood from your scalp due to severe itching.

TREATMENT

Dandruff can be controlled by shampooing your hair regularly. Mild dandruff can be controlled by rinsing your hair daily with gentle shampoo. This helps in reducing oil on the scalp as well as prevents build-up of dead skin and flaking of skin. For moderate or severe dandruff, you can use medicated shampoos, which are available over the counter and should be used only if recommended by your doctor.

If one medicated shampoo is not working for you, then try another shampoo till you find the best shampoo that suits your hair. Do not worry if a particular shampoo is not working for your hair, as different shampoos suit different types of hair. If you are allergic to any shampoo, then stop using it. If you develop any reaction to the products, such as rash or hives, which needs immediate medical attention, then consult your dermatologist.

TYPES OF SHAMPOOS

Initially, medicated shampoos should be used atleast two to three times per week to control dandruff. If there is improvement, taper its use to once weekly. To further maintain and prevent dandruff, use these medicated shampoos at regular intervals.

Medicated shampoos should be used as prescribed by your physician. Read the instructions and warnings on the shampoo bottle before using it, as some shampoos may require more time to show its effect and some may need to be rinsed immediately. Your doctor may also prescribe the antifungal lotions or gels to reduce dandruff. There are different types of medicated shampoos to treat dandruff. They are:

  • Zinc pyrithione shampoos: These shampoos contain an antifungal agent, zinc pyrithione, which reduces fungus on the scalp.

  • Tar-based shampoos: Coal tar slows down the dead skin buildup on the scalp. Use it carefully if you have light-colored hair, as this type of shampoo may cause discoloration of your hair and also makes your hair sensitive to sun light.

  • Selenium sulfide shampoos: These contain an antifungal agent, selenium sulfide, which acts against the fungus on your scalp and slows down the skin cells death. Rinse thoroughly after shampooing, as these shampoos also cause discoloration of your hair.

  • Salicylic acid shampoos: These shampoos help to remove flakes from your hair and scalp, but may cause drying of the scalp, which may aggravate the condition.

  • Ketoconazole shampoos: These shampoos reduce the growth of fungi that are causing dandruff on your scalp. These are available in different strengths and as over-the-counter products.
