More Hair Volume: Hair Diameter

Human hair diameters range from 40 microns to 120 microns. Hair texture is usually classified as follows:*

Fine hair - less than 60 microns
Medium hair - 60-80 microns
Thick hair - greater than 80 microns

Unfortunately, there is very little you can do to permanently increase the diameter of your hair shaft, but you can maximize what you do have by making sure your hair is as healthy as possible. Maintain a nutritious, well-balanced diet, as illness and malnourishment can reduce your hair's diameter.

General Hair Advice

Styling products like mousse or gel can temporarily give the sensation of increased diameter by coating your hair with a polymer film.

Hair Styling Advice

Get the volume that nature didn't give you by using a regimen of styling products that work together to achieve the look you want to keep.
