I am a 60-year old woman, who's been trying various lotions/oils/supplements over the past 2 years for female pattern hair loss, possibly stress-related too. My medications probably don't help, as I'm on various blood thinners and blood pressure tablets. I'm often vitamin D and folic acid deficient, probably due to those too. Two years on, I have lost 2/3rds of my hair volume and although no actual baldness, it's very thin on the crown. Will these laser devices help?
