When an intense itchiness strikes your scalp, it can be hard to concentrate on anything else

And while most cases of a scratchy scalp are totally temporary or treatable, some are a sign of a more serious health condition

If over-the-counter treatments are not working to relieve an itchy scalp, or you develop pain, inflammation, fever or chills, seek medical care

If your itchy scalp is accompanied by snowy white flecks flaking onto your shoulders, you're probably dealing with dandruff

Selenium sulfide can be used to relieve itching and flaking of the scalp by reducing excess scalp fungus and reducing the rate of shedding of dead skin cells

To maintain control of dandruff, lather up with a selenium sulfide shampoo (like Selsun Blue Antidandruff Shampoo or Head & Shoulders Clinical Strength Dandruff Defense Shampoo)

Any number of hair products, including shampoos, conditioners, hair oils or hair dyes, that contact the scalp can result in redness

Creepy crawlies like lice (also known as Pediculus humanus capitis) could be the culprit behind your itchy scalp.
