Mishkat al-Masabih #2541
The Rites of Pilgrimage
The Arabic includes the chain of narration (sanad) and the collector's commentary; the English translation shows the Prophet's words only.
عَنْ عَلِيٍّ وَعَائِشَةَ رَضِيَ اللَّهُ عَنْهُمَا قَالَا: نَهَى رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ أَن تحلق الْمَرْأَة رَأسهَا. رَوَاهُ التِّرْمِذِيّ
‘Ali and ‘A’isha said that God's messenger forbade women to shave the heads.
Tirmidhi transmitted it.
