Hello, happy wednesday!
Thank you for joining us for another installment of #hairmpowerment. This week we're taking it back to basics, starting with hair. Have you ever asked yourself what hair is and why it’s so different though it’s all hair? How relaxers work? Why some hair types are silky and long while others are tough and kinky? Why it comes in different colours and shapes? Our guess is you probably have. Truth is we have all asked ourselves one of these questions before. Ska wara, you've come to the right place. :)
We've put together an Introduction to Hair blog series which will hopefully answer some of those questions. It's a three part series, enjoy.
Welcome to Hair 101
Let’s start with a fun fact before it gets technical, all hair is approximately 91% protein!
Hair starts growing in a follicle below the surface of the skin; this part is called the root. The part that protrudes above the skin is called the shaft. Hair cells are formed in a bulb at the base of the root and mature as they move up through the root. The cells lose their nuclei [die] in the process and fill up with fibrous protein. This is known as Keratinization, named after the fibrous Keratin protein which makes up the hair cells. These dead cells emerge at the surface to join the rest of the chain of dead cells. This is the basis for all hair (African, Brazilian, Indian, Caucasian, Peruvian etc.), it's basically an outgrowth of dead cells. :'D
There are other parts which make up the hair system besides the bulb, root, and shaft. These are just as important. The dermal papilla at the base of the follicle feeds nutrients to the bulb, which is used for cell generation. The sebaceous / oil gland lubricates and coats the hair to prevent moisture loss thus keeping the hair healthy and shiny. Lastly, the arrector pili which is a tiny muscle attached to the follicle, responds to stimulus (fear or cold) causing the hair to contract and make the hair stand up straight.
Well done, you're done with Hair 101. See you in Hair 102. :)
