For hair loss I suggest garlic shampoo and a garlic hot oil treatment, also if your dr gives the ok, add deodorized garlic supplements. I've not yet scheduled my surgery but I suffered from horrible hair loss when I moved from Mississippi to Arizona.

You may be able to find Queen Helene or Nutrine Garlic Shampoo in your local Black BSS. If not, get it from Amazon. Good luck!
