1. Right Down to The Root

 

Right Down to the Root
Your hair grows from little follicles/ roots under the skin.

• The hair shaft is the hair that you physically see.
• The hair bulb is the bulbous (fat/round) area where the hair shaft is generated.
• The sebaceous gland, also known as the oil gland, lubricates the hair, keeping it shiny and healthy.
• The hair follicle is a sac where the hair grows, where the sebaceous glands opens.
• The epidermis is the outer layer of skin that you can see. The epidermis is a barrier that separates the body from the outside environment.
• The dermis is the innermost layer of skin, right under the epidermis. The dermis acts as a supporting structure for the epidermis and contains proteins such as collagen and elastin. Collagen and elastin help give the skin strength and gives it the ability to stretch and return to its original shape
• Arrector pili muscles are the muscles between each hair follicle.
• Subcuntaneous tissues are the third layer of skin that house blood vessels, veins, arteries, and the hair muscle. This layer of skin helps regulate the temperature of the body and protects the arteries and veins.

Web. 12 Nov. 2014. <http://www.hairfinder.com/hairquestions/hairgrowth.htm>.  From this site I learned how hair grows and where the actual hair comes from. I learned that hair comes from little follicles (tiny holes) in the scalp and in the follicles there are the dermal papilla that gives the hair the nutrients it needs to grow.
