Dandruff, or seborrheic dermatitis, is a common condition which is seen in about one out of every 30 people. Flakes can be seen in many different areas, most commonly on the scalp, eyebrows, sides of the nose, and underarms. It is caused by a yeast called Pityrosporum ovale. The easiest form of treatment is with shampoos containing selenium sulfide or pyrithione zinc such as Selsun Blue and Head and Shoulders. The key to treatment is to leave the shampoo on for several minutes. If rinsed off immediately, there is not enough time for the medication to work. An easy thing to do is apply the shampoo immediately after wetting the area(s) as the first part of a shower routine. While waiting for it you can wash your body, brush your teeth, shave, etc.

The cause of rosacea is not clear, but numerous treatments are used. Use of sunscreen, sun avoidance, and cosmetic coverage can be used. Topical medications include metronidazole (most common), sulfur, azelaic acid, benzoyl peroxide, antibiotics, tacrolimus, and tretinoin. Oral medications include various antibiotics and isotretinoin (Accutane). Laser treatments can be used to improve redness and rhinophyma, a large red appearance of the nose. Impressive improvement can also be seen with circular massage for several minutes per day.
