Canada21 participantsStarted 2025-11-07
Plain-language summary
The goal of this clinical trial is to learn whether regular use of Nizoral® Daily Prevent shampoo and conditioner can improve scalp comfort, sleep experiences, mood, and overall well-being in adults who have scalp discomfort and difficulty sleeping. The main questions it aims to answer are:
1. Does using the shampoo and conditioner improve scalp comfort and reduce the impact of scalp discomfort on daily life?
2. Does using the shampoo and conditioner improve sleep experiences and how rested participants feel?
3. Does using the shampoo and conditioner affect mood and other measures of well-being?.
Participants completed a one-week period without hair products, followed by two weeks of using the study shampoo and conditioner at least three times per week. During the study, participants:
1. Attended weekly study visits.
2. Answered questions about their scalp comfort, sleep, and daily experiences.
3. Wore a wrist-based sleep tracking device throughout the study. Completed weekly questionnaires about sleep and scalp health.
4. Took part in non-invasive brain activity measurements during study visits.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
