New Gel May Help Prevent Hair Loss During Chemotherapy, Early Research Finds

Key TakeawaysResearchers developed a gel to help protect hair during chemotherapyIt contains lidocaine and adrenalone, which work by restricting blood flow to the scalpHuman trials haven’t started yet, but researchers are seeking funding.THURSDAY, Sept. 4, 2025 (HealthDay News) — A new shampoo-like gel developed by researchers at Michigan State University could help protect cancer patients from a common and dreaded side effect of chemotherapy: Hair loss.The gel, which has been tested in animal models, is designed to be applied to the scalp before treatment and left on while chemotherapy drugs circulate through the body.“This unmet need of chemotherapy-induced alopecia appealed to me because it is adjacent to the typical needs in medicine such as better treatments and earlier, more accurate diagnostics for cancer,” lead researcher Bryan Smith said in a news release. Smith, an associate professor of engineering, is part of MSU’s Institute for Quantitative Health Science and Engineering.Smith said he began focusing on the issue after interviewing cancer doctors and former patients about hair loss."Once I understood, it became clear to me that better solutions are very important to many cancer patients’ quality of life," he explained.The gel is a water-based gel designed to deliver drugs to the scalp and protect hair follicles. It contains lidocaine and adrenalone, which work by restricting blood flow to the scalp. This helps prevent chemo drugs from reaching the hair follicles, thereby reducing damage and hair loss.The gel also changes with temperature. At body temperature, it stays thicker and clings to the scalp. When at cooler temperatures, it becomes thinner and easier to wash away.The research, publishing in the January 2026 issue of the journal Biomaterials Advances, is still in the early stages and has not yet been tested in humans. “The research has the potential to help many people,” Smith said. “All the individual components are well-established, safe materials, but we can’t move forward with follow-up studies and clinical trials on humans without the support of substantial funding.”More informationThe Mayo Clinic has more on chemotherapy and hair loss.SOURCE: Michigan State University, news release, Sept. 2, 2025 .What This Means For YouIf successful in trials, this gel could give cancer patients a new way to prevent hair loss during chemotherapy..Sign up for our weekly HealthDay newsletter
