What is THYMUSKIN®?
For more than 40 years, people around the world have trusted Thymuskin to help fight thinning hair. Known for its ability to nourish, strengthen, and support healthy hair, Thymuskin provides essential nutrients that promote fuller, thicker-looking hair over time.
Developed in the 1970s by Vita-Cos-Med Klett-Loch GmbH, Thymuskin quickly became a go-to solution for those experiencing thinning hair. Since 1976, the company has focused on creating advanced hair and skincare products using biologically active thymic peptides—ingredients that work with your body to encourage healthier hair growth.
One of their early innovations was GKL-01, a special thymus-based ingredient shown to be effective in addressing thinning hair. Building on that success, they developed the patented GKL-02 peptide complex, which offers the benefits of thymic therapy—without using any animal ingredients.
Today, Thymuskin continues to lead the way with clean, effective, and science-backed formulas designed to help you feel more confident in your hair every day.
