One penny's worth of borax, half a pint of olive oil, one pint of
boiling water.
Pour the boiling water over the borax and oil; let it cool; then put
the mixture into a bottle. Shake it before using, and apply it with a
flannel. Camphor and borax, dissolved in boiling water and left to
cool, make a very good wash for the hair; as also does rosemary water
mixed with a little borax. After using any of these washes, when the
hair becomes thoroughly dry, a little pomatum or oil should be rubbed
in to make it smooth and glossy--that is, if one prefers oil on the
hair.
