Thanks, well they tell me (the Chinese medicine place) that 'results are guaranteed in two weeks'..
Apparently it consists of a tonic/serum that you apply to the scalp and you apply ginger as well (nice smell). It costs £38 and is '100% natural'..
I've read that ginger can increase the blood flow/follicle groth, but who knows what the serum is. I would have to check out the packaging and ingredients to see what it contains. It could well contain bear bile so it would be a no no for me, and it would be interesting to hear of any clinical trials. I doubt it.
