Hair loss associated with a thyroid condition sometimes can improve once you have found the right dose of medicine. Even though hair loss with a thyroid condition is usually temporary, sometimes it can take 6 months or longer to see changes in your hair. The good news it is also clinically proven that red light therapy helps reduce inflammation, increases blood flow, and “re-activates” the scalp helping hair follicles renew. REVIAN may make a positive change for you by slowing hair loss and re-growing and strengthening your hair. Since it is a light-based therapy, there are no chemicals or drugs, so it is also very safe.
