Why hair doesn't get thicker after shave.

The whole hair structure has been made by nature

as such that it is made up of "Proteins, raw elements,

amino acids and bonds work together in forming

hair fiber. The dominant contributor in the 

composition of hair is protein, accounting 

for 91 percent of hair fiber. Amino acids, the 

building blocks of protein, are made up of COHNS elements,

 (Carbon, Oxygen, Hydrogen, Nitrogen and Sulfur)."

And some explanatory images to support my words are shown below.

We all people keep saying that if you cut, shave your hairs it

will grow more. But in actual it all depends upon the size of

your hair pore or we can also say hair follicle, that determines the thickness of that hair.

So people stop worrying about the size of your hair that it will

grow more. Simply trim off any body region hair you want.

The only thing that will happen is the tapering of the hair will

be lost. And hairs will grow from the last cut cross-section.

* Hair follicle: The hair follicle is a dynamic organ found in mammalian

skin. It resides in the dermal layer of the skin and is made up of 20 different

 cell types, each with distinct functions. The hair follicle regulates hair growth

via a complex interaction between hormones, neuropeptides and immune cells.

As shown below.

So i expect that you all would have understood that

to shave or trim hair and fear that the hair will grow 

more is nothing.

As it will remain in the same way.
