I use Hylands Homeopathic Silicea 6X #12. Purchased from iHerb.Small tabs. that dissolve quickly in the mouth. Listed for Skin Eruptions,Brittle Hair and Nails,Pimples,Blackheads and Blemishes associated with common Acne. It has been good for my thinning hair and soft nails,and who knows what internally.
