‘Dandruff’ – excessive scaling of the scalp

Dandruff is the shedding of dead skin cells from the scalp. It is a common chronic scalp condition marked by itching and flaking of the skin on your scalp.

Seborrheic dermatitis is quite a common skin condition that affects the scalp causing an itchy scalp and scaly or flaky skin and stubborn dandruff.

Dandruff and seborrheic dermatitis each cause scaling on the scalp that is often associated with itching. There are, however, distinctions between the two disorders. Dandruff is non-inflammatory, increased scaling on the scalp that represents the more active end of the spectrum of physiologic desquamation.

Seborrheic dermatitis is an inflammatory, erythematous, and scaling eruption that occurs primarily in “ seborrheic “areas i.e. those with high number and activity of sebaceous glands, such as the scalp, face, and trunk.

Symptoms

The common symptoms of dandruff include itching and white, oily flakes. There are several conditions including psoriasis, dry skin, seborrhoeic dermatitis, or contact dermatitis, which present similar symptoms. Before beginning treatment for dandruff, it is important to consult the dermatologists to make sure you’re treating the right condition.

  • *Zinc pyrithione shampoos, contain an antibacterial and antifungal agent ( zincpyrithione) which has been to fight the fungus that causes dandruff.
  • * Tar-based shampoo, contain coal tar, which slows cell turnover and reduces the formation of dandruff’s scaly flakes.
  • * Shampoo containing salicylic acid

Cortisone Creams Reduce Inflammation – It can be taken over the counter in either 0.5% or 1% concentrations. They are safe to use on the face and will often help in just a couple of days when applied twice daily. These products also are available as scalp lotions that are applied once a day, preferably on damp hair after shampooing. You can use scalp cortisone creams together with medicated shampoos.

Antifungal Creams -are more effective apparently because they reduce the number of yeast organisms living on the skin. Over the counter creams include 1% clotrimazole cream and miconazole cream 2% antifungal creams also are applied once or twice a day.

*Oral treatment

Try using one of these shampoos daily or every other day until your dandruff is controlled, then cut back to two or three times a week, as needed.
