Any time someone talks about unexplained dizziness I recall how I for two years went to the doctor and physical therpist to get help for spells of severe vertigo. The answer had nothing to do with a medical problem but was a reaction to the chemicals in my hair product and my make up. When I stopped using them the dizziness was gone for good. Anytime you have dizziness or feel disoriented be suspicious of anything you are using that has toxic chemicals. They are in almost everything.
