Scalp itch is a really common problem, but it can be really easy to treat. Find out why you itch and how you can treat your itchy scalp.
What causes that itchy sensation?
Many things can cause itching, from irritating insect bites and plants like poison ivy, to clothing fibres and skin issues likedandruff.
It’s thought to be a defence mechanism meant to alert our immune system to dangers such as getting bitten by amosquito.
The itchy sensation, also called 'pruritus,' comes about when receptors on the surface of the skin are triggered.
These receptors then send a signal to the brain via the spinal cord, which then causes you to react.
It’s natural to want to scratch…
Our natural instinct when we feel an itch is to scratch it in an attempt to relieve the discomfort.
Scratching temporarily interrupts the 'itch' signal going to the brain, which then reduces the itching sensation. Some scientistsbelieve that the purpose of scratching is to help your body trigger an immune response to fight off invaders.
…But scratching can damage your hair and skin
However, giving into temptation and scratching that annoying itch can damage the skin barrier, sometimes leading tofurther itching.
Scratching your scalp can also permanently damage your hair by stripping away its protective outer cuticle.
Dandruff is one of the most common causes of scalp itch.This is because about half of the population is irritated by oleic acid that is produced by Malassezia globosa (a naturallyoccurring microbe on the scalp). This irritation does two things:
- makes you itch
- makes your body start to rapidly shed skin cells (as dandruff flakes!)
By tackling the root cause of the itch, you help eliminate the temptation to scratch your head, and avoid causing serious damage toyour hair.
