At a meeting of the French Academy of Medicine 1898 it was shown, by photographs, that the use of Thallium to check excessive perspiration caused baldness-the hair rapidly falling out.
This led homoeopaths to speculate whether the same in a potency, say, the 30th potency, would not stop the falling of the hair. No reports.
Ferrum phosphoricum [Ferr-p]
6x and a dilute tincture of Geranium Robertianum, according to Dr. Stoeger, of Switzerland, stopped the hair from falling out of an anaemic young man. The Ferrum phos. was taken internally and the dilution rubbed in the scalp.
Salt water An old recipe is to wash the hair in hot salt water to prevent it from falling out. Use sea water, or put salt in the water when it is heated.
New moon An old idea is to get the hair cut on the increase of the moon to prevent it from falling out. Any time up to the full moon.
Soap Some men say that too much washing, or shampooing, is bad for the hair, as the excess of soap destroys the oiliness.
Arnica oil Possibly it should be termed Arnicated oil. But, be that as it may, what is known as arnica oil has repute among the Germans for years as a means of stopping the falling of the hair and, in some cases, it is claimed, of causing it to grow. The oil is merely rubbed in the scalp about as often as the head is washed, rubbed in thoroughly. It is olive oil, lightly medicated with Arnica.
