Itching on the scalp is very disturbing. This itching can come at any time, especially when you are outdoors during hot weather conditions. Sweat mixed with dirt on the scalp can trigger itching. The desire to scratch also appears, even though this can make the scalp itchy and wounds that lead to infection.
Causes of Head Itching
Not only the weather and dirt are the trigger, but there are several other causes of itching. Here are three causes of itching on the scalp:
1. Dandruff
Generally itchy scalp is caused by dandruff. According to Jessica Wu, MD, assistant professor of clinical dermatology at the University of Southern California Medical School , the medical condition of dandruff is caused by overgrowth of the fungus. The fungus usually grows in places with hair, such as eyebrows, or beards that can develop quickly due to the presence of dead skin cells and excess oil.
2. Allergy
Other causes of itching, may be due to allergic reactions from your daily hair care products.For example the habit of drying your hair with a hair dryer or other tools that give heat to the scalp, or the use of hair spray which can make the scalp dry and irritated.
Avoid using a hair dryer with the warmest temperature, especially when your hair is still very wet, because it can make the scalp damaged.
3. Less humid environment
Itchy scalp can also be caused by environmental factors. Lefkowicz explained, other factors that contribute to scalp irritation due to cold environmental factors with low humidity, and also the effects of wind and sun.
Itchy Scalp Can Cause Serious Problems
Sometimes the scalp is itchy and can be a serious sign for the health of the scalp. If your scalp feels thick, crusty, lots of spots or even scalp bleed when scratched, you might get psoriasis. Psoriasis is an autoimmune disease that affects the skin, characterized by scales accompanied by itching or pain. If these scales are released or scratched, blood will appear under the skin. If accompanied by itching, hair loss or broken.
Or worse, if your scalp often bleeds when you scratch the crust, and is accompanied by pus, you may have a staph infection. Staphylococcal disease of the skin usually results from accumulation of pus. The affected area may become red, swollen, and painful. For this reason, consult a doctor immediately if your scalp is itching continuously, before itching becomes a serious problem.
