Medicated shampoos contain ingredients intended to correct or prevent particular scalp problems, such as itching, dandruff, or scalp dermatitis. No shampoo can either restore or treat thinning hair. Because they are meant to treat specific conditions, they are classified as drugs and are under Food and Drug Administration regulation. Unlike cosmetics, the safety of medicated shampoos must be tested to FDA satisfaction.
A variety of substances that are available in nonprescription medicated shampoos have been found helpful in controlling itching scalp, dandruff, flakiness, and even the more troublesome conditions of seborrheic dermatitis and scalp psoriasis. Through the years zinc pyrithione, sulfur, salicylic acid, selenium sulfide, and tar derivatives have been found particularly effective.
The medications contained in these shampoos have a variety of different functions. Zinc pyrithione and sulfur are used for their antiseptic abilities, sulfur and salicylic acid for their keratolytic effects, and selenium sulfide and tars for their ability to slow down epidermal growth rate. For mild cases of itching scalp and dandruff, I usually advise patients to start with shampoos containing zinc pyrithione, such as HEAD AND SHOULDERS shampoo, ZINCON shampoo, or DANEX shampoo, and using them at least three times a week. For more troublesome or persistent problems, I suggest SELSUN-BLUE, SEBULEX shampoo, IONIL PLUS shampoo, or T-GEL shampoo.
You can use these shampoos daily, if necessary, to achieve or maintain control of your problem. Once this is accomplished, you may find that you need to use a medicated shampoo only once or twice a week to maintain control. To be effective, any medicated shampoo must be massaged well into your scalp and left on for at least five minutes in order to allow the active ingredients sufficient time to work.
Medicated shampoos can often leave your hair dry, lusterless, and smelling like medicine, even when they contain ingredients to specifically mitigate these effects.
