While it may not sound very pleasant to have dandruff, it’s actually the body’s way of dealing with an overgrowth of yeast on the scalp. This causes the skin on the scalp to flake and itch. There are a few different reasons this may be happening, including dry skin, a sensitivity to hair care products, and lack of proper hygiene. Despite this, dandruff is not contagious, and there’s no need to worry about it.
While dandruff itself isn’t contagious, head lice are contagious and can be spread easily from person to person, albeit by sharing articles of clothing. This is especially true among children, as they interact with each other more often. The symptoms of dandruff can range from a whitish or white rash to itching, redness, and thick, greasy scaling.
Although dandruff is easily removed, nits are not as easy to get rid of. Unlike dandruff, which is essentially white and flaky, nits stick to hair strands and are extremely difficult to remove. These tiny insects can be difficult to identify unless they are observed under a microscope, so be sure to be thorough in your examination.
Both dandruff and lice are itchy scalp conditions, and you will know if you have them if you’re scratching your head. The itchiness is caused by the lice’s saliva, which irritates the scalp. You can also confirm if you have lice by pulling out a nit or removing it from your head.
