I Have a Low Donor Density — But I Have a Large Head

Doc,

You talk of “donor densities”, but how about of donor areas? When you saw me a month ago, you told me I have a below average donor density of 1.8 hairs/mm squared and a fine hair shaft and a loose scalp. However, I have a fairly large back of head that can easily fill my Norwood 3A pattern. Will my large head help out the fact that I have a low 1.8 density compared to my caucasian brethren? This is just a curious question since I am not yet a candidate for a hair transplant and have been on 1 mg finasteride since our visit.

Thank you in advance

This is always a demand and supply issue for donor hair. Large heads have more donor hair than smaller heads, but lower Norwood balding patterns (Class 3) means that if you control your hair loss with drugs like Propecia, then your lower than average density may never be an issue for your need for donor hair. Large heads have larger Class 3 patterned areas than smaller heads.
