I always had nice, thick hair, but a few years ago when I became a full-time caregiver, it began to thin due to the stress. When I discovered Finally Hair, my problem was considerably alleviated! It does not take a large amount to cover thin spots nicely, so a bottle lasts a long time. It's great to be able to buy refill bags instead of having to buy a new bottle. I also let my hair go from "blond" to its natural salt and pepper, so can use both the grey and the S & P to my advantage. Thanks for a great product!
