Rehabilitation can be done for facial paralysis after washing and not drying the hair. Rehabilitation therapy mainly includes massage therapy, facial muscle training and physical factor therapy. Facial paralysis after washing hair without blow-drying may be caused by localized cold after washing hair, resulting in decreased resistance and viral attack on the facial nerve, which can be treated with antiviral drugs such as acyclovir, glucocorticosteroids such as prednisolone, and neurotrophic drugs such as methylcobalamin. Generally after the acute stage, doctors will recommend the following rehabilitation measures. 1. Tuina therapy: You can promote blood flow to the face through tuina massage to help relieve facial paralysis. 2. Exercises for facial expression muscles: You can improve your facial movement by doing facial expression muscle exercises in front of a mirror, including opening your mouth, baring your teeth, whistling, and so on. 3. Physical therapy: For the frontalis, buccalis and orbicularis oculi muscles on the affected side with decreased strength, low-frequency electrotherapy can be used to stimulate the contraction of the muscles. In addition, physical factors such as five ultra-short wave, infrared, semiconductor laser treatment can effectively improve the blood supply to the face, and can effectively relieve the edema of the facial nerve. One side of the face muscle weakness after washing hair without blow-drying needs to seek medical treatment as soon as possible, as soon as possible for formal treatment, so as not to delay the condition.
