Plain English Summary
Background and study aims
Dandruff is a common chronic scalp condition that affects more than half of the world's population and has been known since antiquity. 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. The aim of this study is comparing the effects of an anti-dandruff shampoo containing selenium sulfide with a shampoo containing selenium sulfide and piroctone olamine on dandruff, itching, histamine levels or inflammatory markers, and the scalp microbiome in subjects with moderate to severe dandruff.
Who can participate?
The participants of this study are healthy males and females aged 18-65 years old who had not undergone menopause (female) with moderate to severe dandruff.
What does the study involve?
Participants would be instructed to use the randomly assigned shampoo three times a week. Scalp dandruff and itching will be measured at baseline, day 14, and 28. Scalp histamine levels or inflammation markers and scalp microbiome will be measured at baseline and day 28.
What are the possible benefits and risks of participating?
The possible benefits are shampoo and laboratory tests to determine the severity of dandruff, histamine levels or inflammatory markers, and the condition of the microbiome on the scalp, while the risks are a feeling of burning, stinging or pain, accompanied by changes to the scalp in the form of redness, pimples, lumps and/ or discharge.
Where is the study run from?
Faculty of Medicine, Universitas Kristen Duta Wacana (Indonesia).
