Shama-il Tirmidhi Chapter 3, Hadith Number 3 (25).

Baraa bin Aazib R.A. reports: “Rasulullah (SAW) was of average hight, and the portion between the two shoulders was wide. His hair was till his ear lobes”.

This hadith has been explained in the chapter on the mubarak features of Sayidina Rasulullah (SAW). Because of the hair is briefly mentioned here again.
