Shampoos contain ingredients that cleanse the scalp and hair of dirt and natural oils (sebum), and with conditioners can moisturize the scalp. Shampoos also can influence dryness (seborrhea) of the scalp, balance scalp microbial flora, and improve scalp circulation. Certain medical conditions of the scalp such as seborrhea and psoriasis must be treated with shampoos that contain active ingredients as 2% ketoconazole, salicylic acid or zinc-pyrithione.
Dandruff is a common scalp condition that results from an increased proliferation of the superficial skin layer of the scalp. Malassezia spp.is the predominant yeast type in patients with dandruff. Ketoconazole is a mild topical anti-androgen available over the counter to treat dandruff. It is effective for the treatment of dermatitis and dandruff due to its anti-inflammatory and anti-fungal effects, but since it is also an anti-androgen, it may improve hair growth in AGA through androgen dependent pathways.
Conditioners are used as often as shampoos to make hair softer and prevent it from breaking. Various hairstyling aids (mousses, gels, waxes, sprays) add volume and shine to hair as well as help keep it in place. Hair dyes have always been very popular to conceal gray or provide a change in color, but some of their ingredients can cause a contact dermatitis with acute diffuse telogen effluvium. Whether the dye is temporary or long lasting, it is mandatory after every treatment that the dye is meticulously washed out so it does not remain in the scalp.
