HGH topical applications darkening vellus and grey hairs

[thin=depressed]

I have a few greys and thier dark just at the root and half the micro hairs have turned dark as well. I have brownish red hair and I find it odd how dark they have become. Maybe the minoxidil hgh combo is doing this? I don't think there has been NEARLY enough research done on hgh topical because the sh*t increases the mins abilities no doubt.
