For more than 30 years, the THYMUSKIN® 2-step system has been successfully used to fight against thinning hair problems. It is used not only to nourish, reinforce, and strengthen your hair, but also to provide essential nutrients for overall hair care, all leading to noticeably thicker hair. THYMUSKIN® is suitable for both men and women and has no reported side effects. What makes THYMUSKIN® unique is the biologically active ingredient GKL-02 and additional quality ingredients found within the products. That's why dermatologists recommend THYMUSKIN® for scalp and hair care.
