Glad things are looking up for you! Keep in mind too that your hair may have a bad reaction to one product with horsetail (or other ingredient) but it may be fine with another product with the same ingredient....it truly all depends on the formulation of the products.
Keep us posted with what you find that works for you. I try different stuff here and there in hopes of finding replacements for my stash of discontinued HG products that will eventually dwindle away.
Can't wait to hear what Mary Pat had to say! Maybe we're hair triplets!
