Hair loss after dengue fever is a common occurrence, typically starting one to two months after recovery and lasting for several months. The causes of hair loss after dengue fever can be attributed to various factors, including the weakening of the patient's body, nutritional deficiencies, and psychological stress. Dengue virus infection can directly affect the hair follicles, leading to increased scalp hair shedding. The onset of hair loss after acute dengue illness is reported to range from 1 to 3 months, with a mean of 2.1 months. It is recommended for patients to avoid tying their hair too tightly, manage stress, and refrain from chemical processes and heat devices on the hair to aid in the treatment of post-dengue hair loss
