I have retrograde alopecia (hairs on my side [side burns] and nape are thinning quite rapidly), but luckily donor area is safe.. but could potentially end up with a NW6-7 
I'm using S5 cream at the moment. It doesn't seem to be doing much at all. It's almost as if my hair's shedding a lot more (does it cause a shed?)
Or should I use Azelaic acid instead? Which one is better?
Please enlighten me.
