I'm 26 and still grow facial hair like 17 year old. My face is covered in small white unmatured hairs. The only place it is mature is on my lip and chin but even there it is a little thin and patchy in some places. Any idea on what dosage is good for this? I'm taking 50mg zinc supplements and the multivitimins have 5mg of zinc in them, making a total of 55mg daily. Any other tips to help me grow mature facial hair would be appreciated. I look young as it is and my self confidence is incredibly low. The use of has enabled doctors to see inside a patient without having to cut them open. A bit of hair on my face would make me look closer to my actual age and it would help my self confidence a great deal.
