I'm a 41yo black female who is experiencing thinning of my hair. I have a "naturally good" grade of hair, it is shoulder length, and dark brownish-black in color. When I was younger, my hair was much thicker, but has slowly thinned as the years progressed--it has just become much more noticable in the past 10 months or so. Can someone PLEASE help me with some advice as to what to do for this most distressing situation? I am also experiencing severe thinning around my sides. Btw---I live in the northwest section of Philadelphila, PA (if that helps, in case someone wants me to go to a certain shop, etc).
