Is Norwood-Hamilton scale for male pattern hair loss is patented one or is free to use for research?

31 August 2023 1 5K Report

Norwood-Hamilton scale for male pattern hair loss was first published by Norwood OT, in Southern Medical Journal (1975).

Reproduced by Justine A. Ellis, Expert Reviews in Molecular Medicine by Cambridge University Press 2002.

Is the scale patented or free for use in clinical research?

Many clinics across the globe have been using it and also published it on their website/blogs.

David Perez-Meza

It is free, my hair loss and hair restoration colleagues and me, have used it for more than 35-40 years. I use it everyday with my male hair loss patients.
