Hello everyone! My name is Diane Rice and I am 54 years old. After suffering from my own hair loss, I started researching scalp and hair disorders to find a cure for my hair loss issues. Thankfully my issue was an easy fix, deep conditioning my hair more to prevent it from being dry and brittle. But while researching and going through my dilemma I was educated on other hair loss disorders. In my recent endeavors, I am now embracing the world of hair loss and want to make a difference in the life of someone else facing hair loss.
