How are cotton or wool Hair Building Fibers actually made?
What is the actual process that is used to get the cotton or wool into such fine particles? Is there a method someone could do at home to either make their own fibers?
If not, would there be an ideal way to manually dye existing white cotton fibers to match my exact hair color? The fibers are so tiny, I assume a powder would be ideal, but what would be suitable for use on the scalp?
