Excessive sweating on the head can be hereditary, a side effect of a medication, triggered by a particular type of weather or caused by another condition, according to Healthline. Treatment options for localized excessive sweating include Botox, iontophoresis, strong antiperspirants and home remedies.

Botox is used only in extreme cases and impairs the functioning of nerves that cause sweat glands to produce sweat, notes Healthline. Iontophoresis relies on treating the affected area with a weak electrical current to inhibit sweat production. Prescription antiperspirants are used to treat mild cases. Home remedies include using over-the-counter antiperspirants and bathing once a day or more to remove bacteria.

Patients suffering excessive sweating on any part of the body may be suffering from primary focal hyperhidrosis or from secondary generalized hyperhidrosis, explains Healthline. Patients suffering from the former typically begin developing symptoms in childhood and, in addition to the head and face, experience sweating on the hands, feet and underarms. Those suffering from the latter develop excessive sweating as a side effect of a medication or another medical condition.

In patients with secondary generalized hyperhidrosis, excessive sweating may occur over the entire body or a particular area and may also appear during sleep. Conditions that may cause secondary generalized hyperhidrosis include cancer, a spinal cord injury, lung disease, heart disease and Parkinson’s disease.
