I was always told I had a lot of hair too by hairdressers (one rude one even complained once) but I'm wondering now if my hair isn't high density but just medium density and thick-stranded. And here I've been charged extra for having thick hair. Too bad I can't have anybody individually count the hairs on my head to make sure. I want my money back! I think when you know your individual hairs are fine it still looks thick and lustrous you know for sure you're high density.
