Dandruffs

Dandruff can have several causes, including dry skin, seborrhoeic dermatitis, shampooing too often, psoriasis, eczema, sensitivity to hair care products, and more importantly fungi (Malassezia species). The fungal genus Malassezia comprises lipid-dependent and lipophilic yeast species that are part of the normal skin microbiota (Findley et al., 2013). Generally, the Malassezia species such as Malassezia furfur, M. sympodialis, M. solooffiae, M. globosa, and M. restricta are associated with dandruff (Pierard et al., 1995; Leyden et al., 1976). It feed on the natural grease of the skin, from which it produces oleic acid. The oleic acid triggers increased turnover of skin cells, resulting in dandruff. Pityriasis versicolor is a superficial fungal infection caused by Malassezia species. The lesions have a characteristic flaking appearance, although in larger lesions this can be hypo-pigmented or hyper-pigmented. Generally, the lesions take the form of round or oval macules or papules, although in advanced cases the lesions may become confluent. The status of dandruff being amphibious - a disease/disorder, and relatively less medical intervention is sought after for the treatment, dandruff is the most commercially exploited skin and scalp disorder/disease by personal care industries (Ranganathan & Mukhopadhyay, 2010).

So, getting rid of the yeast should improve the dandruff. That is why, the compound having inhibitory activity for the Malassezia species should be employed with either hair creams, hair conditioners or shampoos.
