    Dandruff is a common scalp condition affecting almost half of the world's population. Despite its high prevalence, the exact pathophysiology is not well established and is understood to be multifactorial, with factors such as fungal colonization, sebaceous gland activity and individual factors being implicated. There is a need for an effective and safe shampoo that can target the above factors. Hence, we have developed a shampoo formulation with properties of oil control, moisturizing, non-irritative, anti-fungal, anti-microbial and itch-relieving. In this interventional, open-label study, we evaluated the efficacy and safety of this shampoo in reducing the clinical signs of dandruff and pruritus in patients with pre-existing mild-to-moderate dandruff over a course of 21-day treatment duration through self-assessment and objective clinical evaluations. After continued use of the shampoo, there was a significant decrease in the adherent and loose scalp flaking scores. Mean pruritus scores also decreased significantly across the 21-day time points. There were also no adverse events or skin intolerances reported. This study showed that our shampoo formulation has led to a significant reduction in both adherent and loose scalp flaking and pruritus when used in individuals suffering from mild to moderate dandruff. As such, it is an ideal shampoo, which can be used to effectively control dandruff.

    BACKGROUND: Oxidative stress and inflammation are some of the proposed mechanisms involved in the pathogenesis of atopic dermatitis (AD). Current pharmacotherapeutic approaches are effective yet they are not without adverse effects. Vitamin E has great potential as an adjunctive treatment for AD owing to its antioxidant and anti-inflammatory bioactivities.

    SUMMARY: This review article summarizes the current available evidence from cellular, animal and clinical studies on the relationship between vitamin E and AD. The future prospects of vitamin E are also discussed. Vitamin E in practice does not show any toxicity to humans within a range of reasonable dosage. Albeit rarely, vitamin E as a contact allergen should be considered. Collectively, this review envisaged vitamin E as an adjunctive treatment for AD patients. Future research on the distinct effects of different vitamin E isoforms as well as their delivery system in skin disorders is needed.
