HAIR AND SCALP.

Hi empress,

It sounds like you have dandruff that may be caused by dry scalp. 

Treatments for seborrheic dermatitis are usually applied directly to the skin in the form of shampoo or lotion. Treatment depends on the severity of your condition and your symptoms. Treatment can take several weeks or months and may need to be repeated if the condition recurs.

A wide variety of treatments are used for seborrheic dermatitis. These include:

• Prescription or over-the-counter shampoos containing one or more of the following ingredients:
  • Pyrithione zinc (Head and Shoulders)
  • Hydrocortisone or other cortisone (steroid) preparations
  • Selenium sulfide
  • Salicylic acid, sulfur
  • Coal tar
  • Ketoconazole or other antifungal medications
• Prescription or over-the-counter creams or lotions containing:
  • Hydrocortisone or other cortisone (steroid) preparations
  • Ketoconazole or other antifungal medications
  • Pimecrolimus
