ibn Umar · The Book of Ghusl and Tayammum

"I remember performing Ghusl - myself and the Messenger of Allah (ﷺ), from this" - a vessel like a Sa' or smaller. "We both started taking water from it and I poured water over my head with my hand, three times, without undoing any of my hair."

"The Prophet (ﷺ) used to like to start with the right as much as he could when purifying himself, putting on sandals and combing his hair" - and he (the narrator) said in Wasit (a place in Iraq): "And in all his affairs."
