Hair Glossary

A common problem related to the shedding of dead skin scales from the scalp area.

Some experts believe that dandruff can be linked to hormonal imbalances, chemical reactions to hair or scalp-related products, and even emotional upsets. 

It is also linked to body inflammation and is considered to have a link to hair loss conditions, specifically androgenic alopecia.

A more severe form of dandruff, which includes skin inflammation on the scalp, is known as seborrhoeic dermatitis.

The main symptoms of dandruff are an itchy scalp and flakiness.^[ Red and greasy patches of skin and a tingly feeling on the skin are also symptoms.

The cause is unclear but believed to involve several genetic and environmental factors. 

Dandruff may have several causes, including irritated or oily skin.

Or on dry skin, it's a yeastlike fungus (Malassezia) that feeds on oils on the scalps of most adults.

Dandruff affects about half of adults, with males more often affected than females.  It can start at puberty but tends to wane in adults over the age of 50.

There is no known cure for dandruff as of 2022.

Antifungal creams, such as ketoconazole or salicylic acid, may be used to try to improve the condition.  Antidandruff shampoos are available either by medical prescription or over-the-counter (OTC).
