Efficacy and Safety of TargetCool + Benev Exosomes in Patients With Hair Thinning

United States15 participantsStarted 2025-09-16

Plain-language summary

This clinical trial is testing a new approach to help improve hair thinning using a combination of cosmetic treatments. The purpose of the study is to learn whether applying exosomes to the scalp, along with microneedling and a precision cooling device called TargetCool™. This study aims to determine whether this combination approach offers synergistic benefits for individuals with hair thinning. Exosomes are tiny particles that come from stem cells and contain growth factors and other nutrients. They are being studied for their potential to help regenerate skin and hair. TargetCool™ is an FDA-cleared device that uses precision cooling to reduce inflammation and improve comfort. Microneedling is a common, minimally invasive procedure that uses small needles to stimulate the skin and help absorb topical products more effectively. The study will include healthy men (ages 18 to 70) and women (ages approximately 45 to 70) who are not of childbearing potential. A total of 9 to 15 participants will be randomly placed into one of three groups: Group 1: Exosomes with TargetCool™ Group 2: Microneedling followed by exosomes and TargetCool™ Group 3: Microneedling followed by exosomes only Participants will receive four treatments over 9 weeks. Each visit may include microneedling, TargetCool™ treatment, and exosome application depending on group assignment. A small tattoo will be placed on the scalp to help capture consistent photographs, and a special imaging system (Canfield HairMetrix®) will be used to measure hair changes. Participants will return for follow-up visits at 3 and 6 months after the final treatment. The results will help determine whether this combination of cosmetic treatments is safe and beneficial for people experiencing hair thinning.

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?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

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?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
