Our bodies sweat as a way of regulating body heat. Millions of sweat glands help keep our bodies cool when they are overheated. However, excessive scalp sweating, or hyperhidrosis, can be embarrassing or a sign of an underlying medical condition. It can also be caused as a reaction to certain medications or shampoos. You can reduce excessive scalp sweating by making simple changes in what you eat or drink, changes to your grooming regimen, or additions of natural remedies. If these do not work, you may have to seek a physician's help, which could take the form of medication, injections or surgery.
Drink more water than you now do to keep your body hydrated and cooled. Avoid caffeinated drinks, because caffeine boosts body temperature. Avoid spicy foods, which contain capsaicin, an ingredient that fools the body into thinking it's too hot, inducing sweating in order to cool down. Avoid drinking alcohol, which causes the blood vessels to dilate, which in turn increases body heat.
Avoid anxiety and stress as much as possible, since anxiety is known to induce sweating. Learn stress reduction techniques. A doctor can prescribe an antidepressant if he or she believes it will help.
Change your shampoo to see if your excessive sweating is a reaction to your shampoo. Try menthol shampoo to cool your head down and decrease the oil on your scalp.
Try homeopathic or natural remedies to stop your scalp sweating, including those including Nat mur (Natrum Muriaticum), Lupulus, Castoreum, Argentum Nitricum and Syphilinum.
Seek medical help if simple lifestyle changes, including food and drink changes, do not reduce your excessive scalp sweating. You may have a thyroid condition that can only be diagnosed and treated by a doctor. If you are on hormone-replacement therapy, a doctor can prescribe an anti-oestrogen to help with the sweating problem.
Ask your doctor about anticholinergic drugs, which block activation of the sweat glands. Be aware that anticholinergic medicines may have unpleasant side effects including diarrhoea, rashes and dizziness.
Try Botox to reduce excessive scalp sweating. You will need at least two injections, which must be repeated after four months. A Botox regimen requires a commitment to continue treatment indefinitely.
In extreme cases of hyperhidrosis, where no other remedies have worked, a doctor may suggest an endoscopic thoracic sympathectomy, which is surgery to interrupt the nerve impulses to the sweat glands. Make sure you are aware of all possible side effects or complications that might result from major surgery.
