Many hair products designed to treat dandruff and similar scalp conditions contain zinc pyrithione. This medicated ingredient can provide relief from dry, flaking skin on the scalp, and it can also improve the overall health and look of your locks. You can purchase hair care products that contain zinc pyrithione over the counter, but check with your doctor before you begin using them, informing him of any other medications or products you also use.
Dandruff and Seborrheic Dermatitis
Dandruff and seborrheic dermatitis are characterized by flaking skin on your scalp, which is often dry, itchy and reddened as well. While these conditions do not pose serious health risks, they can be uncomfortable and embarrassing, and they may even lead to temporary hair loss if left untreated. Medicated shampoos that contain zinc pyrithione work to rid your scalp of the bacteria that result in the scaling skin and odor caused by these conditions. This ingredient prevents more of these microorganisms from forming and therefore helps you get your scalp conditions under control.
General Hair Health
Even if you are free of bothersome scalp conditions, zinc pyrithione can benefit your hair. Because it has many antifungal and antibacterial properties, this ingredient helps maintain the overall health of your scalp. It can also improve your hair's body while nourishing it and enhancing its shine. Furthermore, zinc pyrithione can improve your hair's texture, even for strands that you've damaged with chemical treatments or improper care.
Usage and Available Forms
You can acquire zinc pyrithione hair products without a prescription, and it is available in the form of shampoos, sprays, lotions, creams and soaps. For usage on your hair, you should apply the shampoo at least twice a week or as your doctor advises. You will first need to wet your hair and scalp with tepid water, and then apply enough shampoo to work up a good lather, making sure to rub the shampoo into your scalp and through your hair from roots to ends. Once you rinse out the product, you may want to reapply it and rinse again.
Side Effects and Additional Considerations
As with any medication, using zinc pyrithione may produce unwanted side effects, though these are rare, and the most likely one you will experience is a mild irritation of the skin on your scalp. If you notice this or any other side effect, stop using the product and seek medical attention. If you have dandruff or another scalp condition that does not improve with regular usage of zinc pyrithione, you should also see your doctor to determine if you need a different type of medicated ingredient.
