মিশকাতুল মাসাবীহ ৪২৬১

He said God’s messenger often greased his head and combed his beard, and he often wore a head veil as though his garment (the explanation which seems to be preferred is that the word "garment’’ here refers to the cloth like a veil which was used to protect the turban from the grease.) were that of an olive-oil seller.
It is transmitted in Sharh as sunna.

‘A'isha said that when she parted God’s messenger’s hair she made a parting from the crown of his head and let his forelock hang between his eyes.
Abu Dawud transmitted it.

Anas said God’s messenger had sukka (A perfume made from ramik, a black substance mixed with musk. After an elaborate process of pounding and moistening it was left for a year before being used. Its perfume is said to have improved with age. Cf. Mirqat, iv, 463 f.) with which he perfumed himself.
Abu Dawud transmitted it.
