Causes of scalp allergies and specific diagnosis methods

Scalp allergies are very common in life, and most people will experience itching on their heads after scalp allergies occur. So, what are the causes of scalp allergies?

Causes of scalp allergies:

The root cause of scalp allergy is due to the influence of internal and external factors, which cause the scalp's secretion disorder and pH imbalance. At this time, you must use hair care products for sensitive scalp.

The skin on the head is one of the weakest parts of the body, and its thickness is only thicker than the delicate skin around the eyes and lips. When the sun, air pollution, rainy weather, drought and excessive chemicals damage the hair, the scalp is the first to protest: itchy, dry, painful scalp, or excessive oil secretion, dandruff and other phenomena follow. Many people cannot find the reason, so they put all the blame on their own natural bad hair quality, the hairstylist, the shampoo, or lack of time to take care of the hair, etc. In fact, it is very likely that your scalp is allergic.

Strong ultraviolet rays in summer are an important cause of hair damage. Excessive sun exposure will damage the protein tissue inside the hair, making it dry and hard. It will also cause the loss of melanin in the hair and cause the hair to fade. In fact, sun exposure will also cause damage to the fragile skin on the head. Hair needs sun protection, and the skin on the head also needs sun protection. After being scorched by the scorching sun, the skin on the head needs gentle and soothing care to relieve sensitivity. In addition, sweat will greatly change the pH value of the sebum on the head, resulting in a decrease in the skin's resistance. Even the medium-dry skin on the head will secrete more sebum and sweat in summer, so proper nourishment is particularly important. In the midsummer, effectively eliminating harmful fungi on the scalp and keeping the scalp fresh, nourished and moisturized are key care steps for a healthy scalp.
