Selenium is very significant trace element which plays a significant role in the regulation of key cellular functions as selenoproteins (Rayman, 2012). It is an inorganic compound which is found in the form of trigonal and monoclinic crystalline phase. Research have been carried out to examine the application of selenium, and it was observed that Se supplementation can reduce the incidence of different kinds of cancers (Ahmad et al., 2015). Many geographical studies have been noticed that people taking low concentrations of Se in their diets may have maximum cancer mortality rates (Rayman, 2005). However, Se at higher concentrations in the diet is useful as a prooxidant with well-established properties of inhibiting cancer cell growth and also killing them (Aboul-Fadl, 2005). Therefore, the applications of Se compounds in cancer therapy have been strengthened, as proven by much research showing that Se compounds decrease the threat of different kinds of cancers, like exocrine gland, prostate, lung, colon, and liver cancers (Srivastava and Mukhopadhyay, 2013; Beheshti et al., 2013; Gao et al., 2014). The biosynthesized SeNPs from Streptomyces bikiniensis (Ess_amA-1) were screened for anticancer activity and it was observed that SeNPs encourage cell death of Hep-G2 and MCF-7 human cancer cells (Ahmad et al., 2015). Moreover, selenium sulfide is an effective antifungal agent, and it has been used in anti-dandruff hair shampoos for treatment of scalp fungal infections (Eswarapriya and Jegatheesan, 2015).

Nanoparticles are often used in very powerful antibacterial and antifungal cosmetics. However, most metal nanoparticles are rough and often toxic, and there remain concerns about side effects. Sulfur that is biologically compatible with eukaryotes and certified as a soil nutrient is often used in medicine. There is a high possibility that SNP will be used in cosmetics due to their biocompatibility as well as their antibacterial and antifungal properties (Shankar et al., 2018). Baskar et al. (2015) synthesized SNP using CTAB and tested the antimicrobial activity on Malassezia furfur, causing seborrheic dermatitis or dandruff. The cause of dandruff involves the hyperproliferation of keratinocytes, followed by deregulation of keratinization and clumping together of corneocytes that manifesting itself as large flakes of loose skin. For the treatment of dandruff, the keratolytic agents such as salicylic acid and sulfur have been used which loosen the attachments between the corneocytes and allow dandruff to get swiped off. Therefore, sulfur has been used as a common anti-dandruff agent.

Scalp disorders may be short-term or chronic.[4] Stress, abuse of hair products, and harmful exposure to the environment may degrade hair texture and cause allergies, as well as hair breakage and loss.[5] Scalp problems include alopecia areata (AA), dandruff, and seborrheic dermatitis.[6] Dandruff is excessive flaking of the scalp and and may be accompanied by itch.[7]
