What causes white scaly patches on forehead at the beginning of hairline?
Patient: i am puja studying mbbs , i am having white scaly patches ( medium size)on starting of my forehead where hair starts ,its from 1 week only i am thinking dandruff (because i am having it) .recently i changed my shampoo 4weeks back i think that may be the reason please help me .i am fearing may i have seborrhic dermatitis so plz help me Doctor: Hi puja and welcome to HCMBefore going into the diagnosis, just wanted to know if you have had similar complaints any time in the past, anywhere else on the body, on elbows, knees or on the trunk, soles and palms?Do you generally have any other skin condition or allergies/eczema?is there a family history of similar complaints?As per your description and short duration, you could have seborrheic dermatitis which is also a type of dandruff with flaky skin and itching. It is nothing to worry about. It may also affect other oily areas like face, chest, upper back. Change in climate, change in shampoo or anything causing oiliness on the scalp could cause an increase. Make sure not to apply more greasy gels, styling products and to wash off conditioner well as this can also dry up and look flaky. Keep your scalp clean and oil free.Another important diagnosis is scalp psoriasis along the hairline. So it is necessary to consult a dermatologist to examine and rule it out. It maybe seasonal as well and may spread.For now apply Salisia-KT or similar shampoo twice a week, avoid prolonged oil application. Take an antihistamine like Levocet for itching if needed.Eat healthy and cut down on oily, fried foods. Further supplements can be given after examination.See a dermatologist as advised.Hope this helps you.
