Does washing your hair every day help get rid of dandruff and reduce oily hair?

Many people have a habit of washing their hair every day, or even several times a day, hoping to keep their scalp clean and less oily. However, dermatologists warn that this can worsen the condition.

You should only wash your hair 2-3 times a week.

Many people complain that even though they wash their hair every day, it becomes greasy, their scalp gets dirty, and dandruff appears after only a few hours. Wanting to completely eliminate the flaky patches and the "heavy feeling of oiliness," many choose to wash their hair multiple times, combined with vigorous scrubbing to "push" the dandruff out of their scalp.

According to Dr. Nguyen Thi Tuyen, Deputy Head of the Department of Skin Diseases in Women and Children at the Central Dermatology Hospital, in people with seborrheic dermatitis, the skin's protective barrier is weakened, leading to scaling (also known as dandruff).

"However, washing your hair too often can severely damage the scalp, making it dry due to the loss of its natural protective oil layer," Dr. Tuyen explained. Furthermore, vigorous scrubbing makes the scalp more susceptible to harmful external factors such as bacteria and viruses, worsening the condition of the scalp.

You should only wash your hair about 2-3 times a week and avoid rubbing or scratching your scalp vigorously.

According to doctors' recommendations, people should only wash their hair about 2-3 times a week and avoid scrubbing or scratching the scalp vigorously. Hair washing should only be done when necessary and should not become a daily habit as it can damage the scalp and hair follicles.

On days when you don't wash your hair but it still feels greasy, you can consider using dry shampoo.

Is a dandruff-prone scalp a sign of a medical condition?

Dandruff is a fairly common natural phenomenon, which can stem from scalp characteristics or inappropriate hair care habits.

People with oily scalps and overactive sebaceous glands are more prone to developing thin, moist, white dandruff flakes. Conversely, dry scalps, especially in cold weather, are also more likely to cause itching and flaking of dandruff.

Poor hair hygiene habits are also a common cause. Washing your hair too often exposes your scalp to detergents in shampoo, leading to dryness, itching, dandruff, and hair loss.

Meanwhile, washing your hair too infrequently also causes dead skin cells, sweat, and oil to accumulate, forming flakes that clog the scalp.

Many medical conditions cause scaling similar to dandruff.

Besides being a normal physiological phenomenon, persistent dandruff can also be a sign of several scalp conditions. Among them, scalp fungus can cause the skin to flake off in white patches resembling dandruff, accompanied by a red base, raised edges around the lesions, and a risk of hair loss.

Scalp psoriasis also manifests as excessive shedding of white, flaky scales. Seborrheic dermatitis causes the scalp to develop thick, white or yellowish scaly patches that may be dry or moist.

Additionally, contact dermatitis caused by allergies to chemicals such as shampoos, hair dyes, or hairspray is also a common cause of itchy and flaky scalp.

Doctors recommend that if dandruff is persistent, recurs frequently, or is accompanied by itching, redness, or hair loss, people should consult a dermatologist for examination, testing, and accurate diagnosis.
