RECOMMENDED RECIPES IN "DE ORNATU MULIERUM" FOR THE HAIRCARE:
FOR BLOND HAIR DYE :
1) For coloring the hair so that it is golden. Take the exterior shell of a walnut and the bark of the tree itself, and cook them in water, and with this water mix alum and oak apples, and with these mixed things you will smear the head (having first washed it) placing upon the hair leaves and tying them with strings for two days; you will be able to color. And comb the head so that whatever adheres to the hair as excess comes off. Then place a coloring which is made from oriental crocus, dragon's blood, and henna (whose larger part has been mixed with a decoction of brazil wood) and thus let the woman remain for three days, and on the fourth day let her be washed with hot water, and never will be removed easily. 2) Let cabbage stalks and roots be pulverized and let pulverized shavings of boxwood or ivory be mixed with them, and it should be pure yellow. And from these powders, let there be made a cleanser which makes the hair golden.
TO OBTAIN LIGHT HAIR :
-After leaving the bath, let her wash the hair with a cleanser such as this: take ashes of burnt vine, the chaff of barley nodes, and licorice wood (so that it may the more brightly shine), and sowbread. Boil the chaff and the sowbread in water. With the chaff and the ash and the sowbread, let a pot having at its base two or three small openings be filled. Let the water in which the sowbread and the chaff were previously cooked be poured into the pot, so that it is strained by the small openings. With this cleanser let the woman wash her head. After the washing, let her leave it to dry by itself, and her hair will be golden and shimmering. http://thehistoryofthehairsworld.com/middle_ages_renaissance.html
