Thinning hair and hair loss are common issues that affect most adults at some point in their life. Research shows that hair disorders affect nearly 75% of women over age 65 and over half of all males over 40. While hereditary hair disorders are the most common, many issues can cause thinning hair and hair loss, each requiring a proper diagnosis for treatment to be effective. For many individuals with thinning hair and hair loss issues, low-level laser therapy has proven to be an effective treatment, stimulating hair regrowth and helping to restore a full head of hair.
