To whiten hair in the shade, without sun, so that it will be as white and shining as silver.
Take 4 ounces of the root of greater centaury, 3 ounces each of gum arabic, tragacanth and rock alum, 2 ounces of white Damascene soap, 1 lb. of white precipitate of alum and 25 lb. of running water from the river. Take the root of the centaury and the same amount of its leaves and cut it very finely and boil everything together until it is reduced 1/3. Then let it stand in the sun for 15 days to become clear. Strain it and save it for your needs. To make the hair blond, rub it on your hair in the morning and wrap your hair in a kerchief and at noon wash the head with ordinary lye in which was boiled 1 handful of pellitory of the wall. Dry it where you wish, by the fire or in the sun, and continue in this way until finally you see your hair white and blond. Also at the same time it will take on a most beautiful shine that lasts for a long time. Know that this blond color is used a great deal in and around Venice and happy is the lady who knows such a secret.... 44
To make the white hair of the head, beard or hair on the skin become dark brown.
Take ordinary lye and wash the head and when it is completely dry, rub the hair, beard or hair on the skin with well-warmed oil of tartar with a sponge. Do this at least 2 or 3 times a day and in 3 or 4 days the hair will have changed color to brown and the color will last several days. This secret was used to please the lover of a spruced-up Venetian lady who was 60 years old and she used only this oil and her hair was very shining. If this secret does not seem to have produced the right color for hair or beard, in the last combing with a comb of lead, rub with oil of benzoin gum which will give it a sweet odor. This secret is to be held dear. It has been tested by me, Master Apothecary Andrea, many times.

Another to make the hair or beard white.
Take 1 and ½ handfuls each of flowers of mullein, French lavender, celandine and ashes of white grape vine and make lye and put 2 lb. of white soap cut finely into 8 lb. of lye and put it in a glass vessel in the sun for 20 days and each day stir it up with a stick so all is suspended. Then wet the hair with this many times with a sponge while standing in the sun. The hair will become most beautiful and lustrous by following this method of the great Venetian ladies. This is a secret that many ladies know.

Another to make the hair become long, down to the ground.
Take some maiden hair fern and dry it in the shade and make fine powder of it and put it in myrtle oil and when the hair is dry, rub the hair and the scalp with it. Do this several times and it will become long. It has been tested.
To make the hair black when it is white.
Take 1 ounce each of liquid storax, storax in canes, benzoin gum and sedge, ½ ounce each of cloves and orris root, and 1 lb. of oil of sweet almonds. Then take the benzoin gum, cloves, orris root and sedge and make them into fine powder and incorporate with the other things and distill them in a glass still on a slow fire and collect the liquor that arises and save it in a glass vessel. In the evening when you go to sleep, rub your hair or beard very well and wrap it in a linen cloth until morning. Then rub it with another dry cloth. Two times a week wash your head and when it is dry, rub it carefully. Continue this for several days and you will see it become dark, very dark, and every 2 months or more you can rub it to maintain it in that color and it will have a very good odor. Do it and this will succeed well for you.... 45
