My mom has been obsessing over her nails. She files them every day, several times, and buffs them for 20 minutes at a time. It is driving me crazy!!! When it's not her nails, she seems to find something else to obsess over. Her hair is thinning, and she's obsessing over that as well. We tried Rogaine and several different shampoos. The doctor said that it's not due to medication, checked her thyroid again, and thinks it just aging.
