So I've been doing some research on different hair units (trying to decide what would be best for me). I still have my own hair but I am tired of it looking thin and not feeling comfortable going swimming or even sitting in the sun without thinking about my scalp showing through. I don't want to take Rogaine and save my existing hair by putting foreign chemicals in my body. Anyhow, these are the options I have discovered and I'm wondering if anyone out there can shed some light on them…
