The Kitáb-i-Aqdas
68.Shave not your heads   ¶44
In some religious traditions it is considered desirable to shave one’s head. The shaving of the head is forbidden by Bahá’u’lláh, and He makes it clear that the provision contained in His Súriy-i-Hajj requiring pilgrims to the Holy House in Shíráz to shave their heads has been superseded through this verse of the Kitáb-i-Aqdas (Q&A 10).
