Dandruff (Pityriasis simplex capillitii):
Affects approximately 50% of the population in some mild to severe form.

My dermatologist told me the best way to get rid of dandruff is to:
1. Alternate between three different shampoos with different main active ingredients.
2. Shampoo in the sink and leave it on for 5 min. before taking a shower and rinsing it out.

Dandruff is usually caused by the body's natural reaction to Malassezia globosa (M. globosa), the dandruff-causing fungus that lives on the scalp of 100 percent of the adult population.
Dandruff can also be a manifestation of an allergic reaction to chemicals in hair gels, sprays, and shampoos, hair oils, or sometimes even dandruff medications like ketoconazole.

Fungicides such as ketoconazole, zinc pyrithione and selenium sulfide reduce loose dander by killing the fungus.

Fungus' include: Malassezia globosa, Malassezia furfur and Pityrosporum ovale yeast.

Active Ingredients
The following active ingredients and shampoos are effective against fungus.

Salicylic acid, and coal tar belong to a class of drugs known as keratoplastics. They work by causing the skin to shed dead cells (peeling agent) from its top layer and slow down the growth of skin cells.

Salicylic acid - Extra Strength Protection | Denorex Shampoo - T/Gel therapeutic conditoner
Coal Tar - T/Gel Original Formula, Denorex Therapeutic Protection

Valisone (Betamethasone Valerate) is commonly prescribed for dandruff.

Side Effects:
Some of the ingredients of dandruff shampoos can cause skin irritation and other side effects.
Coal tar is thought to be a carcinogen at high doses, although this isn't thought to be a problem at the low doses found in anti-dandruff shampoos.
