Hey,
well i use the dropper and it's a pain in the arse. The spray, I am not sure its getting down to the shafts.
I am a NW 2 with the island. My hair is wavy so it gives good coverage and you have to lift up my hair on the sides to see the thinning areas. I an not crazy about the minox/azelaic acid 5% b/c it makes my hair look like I put log cabin syrup in it.
I know I am being anal but I used the minox/retin A combo for yrs utilizing the spray and applied it to my hair as well b/c the MD said it wouls work its way down to the shaft. Who knows maybe I was applying it worng all these yrs. I never massaged it in.
