Sorry to hear your hair is not well.
There are 3 causes of mine falling out over the years, heredity, unbalanced diet, and certain medicines.
The doctors suggested biotin and minoxidil. Dr. Oz on his show suggested evening primrose oil.
I have seen no help to stop my hair from falling out by using biotin. It only makes my hair and nails grow like well watered grass in the summer, but I do it. Afraid to stop.
The minoxidil keeps what is left of my hair from falling out. Don't let it get on the skin where you don't want hair,(:>). I only use it once a day or sometimes every other day. The trouble is when you stop using, all that hair which was going to fall out; falls out! Get the store brand. Same ingredients.
Evening primrose oil, who knows. I do it anyway.
