I am so sorry about your bald spot, after my mother going through losing mass amounts of hair I have to give my little two cents. Well if you have been visiting the forum at all you would know that indian hair care is all the rage here, so circulation to the scalp is very important, scalp massages are a must, get stimulating scalp oils: mustard oil, coconut oil, alma oil are a few to start out with for your messages. Also, I remember a long time ago hearing that talking alfafa pills help with balding, so please give that a try or eat the real vegetable regular. And I would highly suggest you stop using shampoos with sulfates. Try a shampoo bar from a vitamin shop or organic health store, or even the shikakai powder. Very moisturizing and should eventually help with getting your shedding under control. I am no expert at this so I hope that others chime in. I know the search engine can be crappy sometimes, but try that too. You might even want to use google. You will find many forums, black, white, indian, etc talk about natural cures to remedy problems such as yours. May your scalp be healed, AMEN!
God Bless.
