I have been using topical certizine for 2 months now alongside minoxidil and regenepure which i have used for over one year. minoxidil gave me back all my hair except for my temples. Now after just 2 months since adding certizine 2-3 times a day, i have gotten real growth in my temple region which was practically slick bald. The reason for this growth is that i think the speculations are true that minoxidil is stimulating pge2, while certizine inhibits pgd2 (and perhaps even sadly lowers pge2). But the negative effect from certizine on pge2 is faught away by the much stronger positive effect on pge2 from minoxidil. I can upload pics if anyone wants to see. Thoughts?
