I'm 60 yrs old with hair thinning. Every day I lose a lot of hair. This has been happening for almost a yr. I don't have bald spots yet but probably will soon. The derm recommended Minoxidil for men. He also sold me expensive shampoo & conditioner from DCL Labs & then I learned that they are bad because they are not sulfate free. My hair loss is probably from stress or medication. Any advice or similar problem? I do take Biotin every day and thyroid is fine.
