Scalp Condition


Most common scalp problems seen by a trichologist are:

Dandruff (called Pityriasis capitis or Pityriasis simplex). The yeast Malassezia ovalis has a major role in triggering the condition. Usually characterized by diffuse loose white flaking.

Seborrheic dermatitis is a common skin disorder that mainly affects the scalp, eyebrows, sides of the nose, and behind the ears. Usually characterized by yellow flaking and some skin redness (erythema).

Psoriasis on the scalp is a bright pink, very inflamed skin covered in thick silvery scales. Usually characterized by severe itching (pruritus) and bleeding when scratched.

Qu.     What causes dandruff?

˜The cause of dandruff is not fully understood; however, it is thought that the yeast Malassezia ovalis, which is naturally found on the skin, has a major role in triggering the condition in some people.  You may have dandruff if you have small white or grey scales on your scalp which, when they become loose, can be seen on the hair shaft or on the collar and shoulders.  Sometimes the flakes can become greasy from scalp oil giving them a yellowish color.  Dandruff often begins at puberty and continues through adulthood.  It usually becomes more severe at about 20 years of age and becomes less frequent after 50.  Some researchers believe diet, stress, and climatic changes can influence the severity of a dandruff condition.

Qu. Can I catch dandruff from my friend’s brush?

No.  Dandruff is not contagious.  However, its best to keep your brushes and combs as clean as possible for normal hygienic reasons.  They should be washed approximately once a week in mild soapy water.

Qu. I have psoriasis on my scalp, will this cause my hair to fall out?

Psoriasis is a disorder of the skin which frequently involves the scalp (it can also occur on other parts of the body).  Although severe hair loss rarely occurs with psoriasis, some increased shedding of the hair and some reduction in hair density can occur.  Psoriasis is often treated with corticosteroid creams and, in severe cases, with ultraviolet light treatments.

Qu. Why does my scalp gets very oily?

Oil (known as sebum) often leads to greasy, limp, unmanageable hair.  The amount of oil that your scalp produces can depend on many things, including diet, stress, hormonal changes, genetic factors, age, etc.  For example, teenagers who are noticing more acne often also complain of oilier hair.  Men and women with genetic hair loss may also complain of extra scalp greasiness.  Increased hair washing with shampoo may help.
