Hi I am new to this forum. I just bought 2 bottles of 15% Minoxidil and 5% Azelaic Acid for my thinning hair and am now waiting for delivery of them. I used to use Spectral DNC which seem to help a lot but I am hoping to have better results with the 15% minoxidil and the Azelaic Acid works as a DHT blocker. Has anyone used any concentrations of Minoxidl? If you did were your results better? Have you had any side effects? Any info anyone could give me would be great. I know woman aren't supposed to use the 5 % because of growing facial hair and other side effects but I never experienced any side effects when using the 5% in Spectral DNC.
