My scalp itches after washing my hair

The phenomenon of itchy scalp after washing hair occasionally occurs. There are many reasons for this phenomenon. If the quality of shampoo is not good, it will cause itchy scalp after washing hair. Sometimes due to personal physical problems, people will have allergic reactions to certain shampoos, so this phenomenon will occur. This phenomenon is also directly related to the temperature of the water. Let us take a closer look at the problems related to itchy scalp after washing hair.

Four things to note when washing your hair:

1. Washing your hair too often is not worth it

Generally 2-3 times a week in spring and summer, 1-2 times in autumn and winter. Frequent use of shampoo can easily cause hair to become dry, dull, and split. In addition, frequent washing reduces the oil content of the scalp, and the skin compensates by increasing oil secretion, making the area oily. This vicious cycle destroys the normal oil and metabolic environment of the scalp and can easily lead to seborrheic dermatitis.

2. 30° water temperature is the most suitable

Around 35°, if the water temperature is too high, it will stimulate the oil secretion of hair, while if the water temperature is too low, it will shrink the pores, making it difficult to remove dirt. Therefore, a water temperature of around 30° is recommended.

3. Scratching your scalp can easily lead to folliculitis

Rub and massage with your fingertips. Fingernails can harbor dirt and grime. Some people like to scratch their scalp vigorously. Scratching not only causes the local skin to produce itching substances such as histamine, but also dilates capillaries. The pleasure of scratching causes a vicious cycle and causes dermatitis, etc. Scratching vigorously can also easily lead to damage of the skin barrier, making the local area susceptible to bacterial infection and causing folliculitis.

4. Do not apply shampoo directly to your hair

Applying shampoo directly to the scalp can easily irritate the scalp and may aggravate the formation of dandruff. Some people who are allergic to certain ingredients in shampoo may also easily develop dermatitis. The correct way to use shampoo is to rub it in the palm of your hand to create rich foam.

Precautions for using conditioner

Using conditioner after shampooing can not only moisturize the hair, but also balance the acidity and alkalinity of the hair, so that the hair can obtain nutrition and moisture. When using conditioner, you should also pay attention to the following two matters:

1. Applying too much conditioner can make your scalp oily

Applying conditioner to the entire scalp will waste conditioner and easily cause a greasy scalp. The hair near the root is new healthy hair. Only the part near the ends of the hair is aging, split, and damaged. so. After washing your hair, simply apply from the mid-lengths to the ends and massage for about 1 minute to evenly distribute the conditioner. For oily hair, use conditioner only on the drier ends.

2. Conditioner residues are harmful

Residual conditioner will stimulate the sebaceous glands to secrete excessive oil, which is harmful to the health of the scalp. Some hair conditioners can also cause dandruff. Conditioner residue and local humid environment are conducive to the breeding of fungi and bacteria, such as Malassezia, Staphylococcus aureus, etc., which can easily lead to folliculitis. In addition, some conditioners contain aromatic carcinogens, preservatives, fragrances, and surfactants, which are adsorbed on the scalp. At the very least, they can irritate scalp allergies, and at worst, they can promote skin tissue cancer. This is harmful to the scalp and physical health.
