This was the product of the Anglo-American Drug Co. of London. They were listed in 1884 at 33 Farringdon Road, London. The product was advertised at least as early as 1875. The last ad I found for them was in a 1920 issue of the same.
The British Medical Association examined its contents in 1912, and found it to contain about 94% rose water, 19% glycerine, 1% precipitated sulphur, and .1% lead acetate. The chemists mentioned that the second bottle they examined contained about 8 times as much lead acetate. The transcription below was included in their article.
THE MEXICAN HAIR RENEWER.
For restoring grey hair to its original colour without dyeing it, For renewing or causing hair to grow on bald spots. For preventing dandruff and the hair from falling out. For making the hair soft, glossy, pliant, and luxuriant. Daily application of this preparation for a week or two will surely restore faded, grey, or white hair to its natural colour and richness. If properly applied, it never fails; but it should be well shaken before using. It is not a dye, nor does it contain any colouring matter or offensive substance whatever. Hence it does not soil the hands, the scalp, or even white linen, but produces the colour within the substance of the hair. In many cases it has been successful in causing new hair to grow on bald spots, and it can be confidently recommended in all cases, unless the hair-glands are decayed; for if the glands are decayed and gone, no stimulant can restore them; but if, as is often the case, the glands are only torpid, "THE MEXICAN HAIR RENEWER" will renew their vitality, and a new growth of hair will follow.
