The Medical Council says : 



The first step in any treatment for 

 dandruff and baldness should be a 



SHAMPOO ^ith 



Packer's Tar Soap. 



Shampooing is made delightfully refreshing, and a real luxury, by the use 

 of Packer's Tar Soap. Its known purity, its excellent cleansing, invig- 

 orating, and antiseptic properties, have secured for this soap the highest 

 commendation of physicians and hair-dressers, not only for cleansing and 

 preserving the hair, but for use in treatment of dandruff and baldness.
