Dandruff is a common condition caused by a combination of three natural factors:
1) a fungus that lives on everyone’s scalp
2) the presence of scalp oils (which we all have)
3) one’s susceptibility to the condition, similar to an allergy.
Anti-dandruff hair care products include ingredients such as zinc pyrithione, considered by the dermatologist as effective anti-dandruff treatments. It is especially important for dandruff sufferers to shampoo frequently to keep scalp oils from accumulating on the scalp and exacerbating the condition of dandruff.
