CHAPTER XXI 



CARING FOR THE HAIR 



If you pull out a hair from your head, you will see how 

 long the root is and what it looks like. All you find is a 



bit of flesh on the end of the hair. 

 The picture shows what that 

 bit of flesh really is. The pit 

 which the hair stands in is called 

 the hair cell. It is plain, there- 

 fore, that when you pulled out 

 the hair, the entire lining of the 

 cell came with it ; in other words, 

 you pulled out the whole won- 

 derful cell with everything that 

 was in it. That is what you see 

 on the root of the hair in your 

 hand. 



The truth is that each hair 

 stands alone like a small tele- 

 graph pole in its own little cell ; 



each ^ separate f rom eyery other 



one; each has its own muscle, its own oil glands, and you 

 would be able to see them plainly under a microscope.
