Hair loss--anyt tips?

I am very happy with my progress. I am 5'10" and I am down to 179....I have lost 84 lbs in 7 months...which is pretty awesome. However, I have some hair thinning. Luckiy, I started with very overly- thick wavy/curly/somewhat frizzy hair. Now, it is thinning, and looks fairly normal, only because I had way too much hair to begin with. It is pretty dry & frizzy, mostly the ponytail and ends (I have past the shoulder lentht hair)

What has anyone found that helps this? I have read that after 6 mos or so it should start to come back? I really don't think it is super noticeable, I am hoping the fact that my whole face and body have changed takes away the noticeability that I used to have full, crazy thick hair (think 1980's rocker-hair bands!) and now it is more like a regular/slightly thin look....but yeah, dry and frizzy. i really notice it when shampooing, it feels like I have hardly any hair!

Any tips?
