There is no authoritative information to prove that washing hair with water can improve the symptoms of hair loss, so washing hair with water is generally useless for hair loss. There are many reasons for hair loss, and the cause should be clarified and then treated accordingly.
Generally speaking, washing hair with water cannot improve or treat hair loss, and washing hair with water only for a long time will lead to hair and scalp not being thoroughly cleaned, and long-term accumulation of dirt, which may lead to hair follicle blockage and aggravate the symptoms of hair loss.
There are many factors leading to hair loss, such as physiological factors, congenital factors (congenital alopecia, dysplasia, etc.), endocrine disorders (androgenetic alopecia, hypothyroidism, postpartum alopecia, etc.), systemic diseases (anemia, malnutrition, etc.), and physical factors (X-ray irradiation, scalded, etc.), and there are differences in the treatment modalities for hair loss caused by different factors.
It is recommended that patients with hair loss should consult a doctor in time in order to clarify the cause of the disease and carry out targeted treatment. In daily life, you should pay attention to scalp hygiene and use regular shampoo to wash your hair.
