As for what shampoo to use there is only one. It is egg and borax.
To use it, wet the head thoroughly with warm water take the yolk of a raw new-laid
egg and rub this well into the scalp, it will lather quite like soap. Keep on rubbing
long time, then rinse in warm water to which borax has added in the proportion of a
heaped teaspoonful to each quart. Rinse in a second and even in a third water if
necessary,adding borax to each. Dry with towels or before the fire or sunshine.
If you happen to have long hair, brush for an quarter of an hour before it is quite dry. The gloss and softness which will result will amaze you.
