What can make thin hair thick?

[NG]

Hi, what can make thin hair grow in thicker. Not just a condition that only coats the hair but I'm looking for something that will make the hair grow thicker. Is there anything? Thank you.

minoxidil has made my hair thicker, aside fom me having naturally thick hair. It works like a supercharger. I love it.
