If you’re scratching your head over what’s causing your itchy scalp, it’s worth noting that flaky and inflamed skin on this part of the body affects most women at some point. So while thoughts automatically turn to a head lice infestation, the reason for your discomfort could be anything from dandruff to an allergic reaction.
We rarely think about our scalps as being an extension of the skin on our foreheads, largely because we can’t see it. Out of sight, out of mind, really does apply here. But Anabel Kingsley, brand president and trichologist at Philip Kingsley, says we would be remiss to ignore an itchy scalp or any other symptoms that suggest it has been thrown out of whack.
“A scalp condition needs consistent treatment and care to help to bring it under control, in the same way as a skin condition,” Anabel explains, adding: “You would prevent yourself from scratching and itching your skin on your face or body, and you should try to do the same with your scalp.”
As ever, identifying the root cause is the first step to less inflamed skin and being back on good terms with your hair. With the help of a panel of experts, we reveal the 14 reasons your scalp may be itchy – and how you can rectify it.
1. Dandruff
Dandruff is one of the most common reasons why people have an itchy scalp. Contrary to popular belief, though, dandruff is not caused by dry skin, so applying a trusty hair oil will only make matters worse. “Dandruff is almost always oily,” says Anabel. “So applying hair oils in a bid to clear it simply results in stickier, greasier flakes.”
A yeast-like fungus called Malassezia is responsible for the snowy white flakes that drift down and settle on your shoulders. There are many over-the-counter products laced with antimicrobial agents, such as piroctone olamine, you can use to treat dandruff, including the Philip Kingsley Flaky/Itchy Scalp Anti-Dandruff Shampoo.
Hair stylist Kala Kilshaw recommends choosing a shampoo containing zinc (Redken Scalp Relief Dandruff Control Shampoo, is good) to help relieve the itchiness. She also maintains that not going to bed with damp hair will help to prevent scalp fungus and irritation.
2. Psoriasis or eczema
Another common cause of an itchy scalp is psoriasis or eczema, which are inflammatory skin conditions that can appear on the scalp. “They’re not contagious and can’t spread from person to person,” says Wil Fleeson, owner of Rainbow Room International’s Stirling and Buchanan Street Salons and director of Trichology Scotland.
“However, you can be more likely to develop psoriasis or eczema if someone in your family has it. Both conditions cause red, scaly and itchy patches on the scalp, but, like dandruff, these conditions can be treated to reduce the symptoms,” he continues, adding that you should always visit a trichologist to work out the correct treatment plan based on the severity of your condition.
