Why does my scalp always itch?

Itchy scalp is related to oily hair. Excessively oily hair can lead to inflammation, redness, and swelling of the scalp, resulting in itchy symptoms. Lack of moisture in hair and infrequent shampooing can also cause persistent itchy scalp issues. Less frequent shampooing tends to promote dandruff growth, and the increased amount of dandruff can cause irritation and lead to itchy scalp.

1. During seasonal changes, especially in the transition from autumn to winter and from summer to autumn, dryness, peeling, skin itching, and moisture deficiency are more likely to occur. At the same time, dandruff may increase, and severe scalp itching may result.

2. When washing your hair, avoid using excessively hot water, which can also easily cause itchy scalp.

3. If you experience itchy scalp due to fungal infection, a fungal immunofluorescence test may be necessary to determine the presence of fungal infection. Once fungal infection is detected, appropriate antifungal treatment should be administered.

4. Sudden itchy scalp after switching to a new shampoo or after hair dyeing, along with palpable bumps on the scalp, may be due to allergies. In such cases, anti-allergy medication can be taken.

5. For oily hair, excessive sebum secretion from the scalp glands can clog pores, leading to seborrheic dermatitis or folliculitis, which can also cause itchy scalp.

6. If you do not shampoo frequently, excessive oil accumulation at the roots of the hair, combined with sweat and dirt from the scalp's sweat glands, can clog the sebaceous glands, impeding the excretion of sebum and sweat, causing skin irritation and itchy scalp.
