Continuing on our journey to understand our hair better, let’s begin with a quick recap of part 1 –
Hair is growing but is made of dead tissue!
Ever wondered why we do not feel any pain when we cut or iron our hair!!!
Hair can basically be divided into 2 parts: Hair shaft and hair bulb or follicle
Hair shaft is the visible portion of hair – the thick dark strand that covers our scalp. This is formed of specialized skin cells. It does not have any blood supply or nerves – hence we neither bleed nor feel any pain when we cut our hair. This is made of compressed protein chains called Keratin.
Hair follicle that is the deeper portion of the hair (that we cannot see) is located deep into the skin. This is where the hair gets its blood supply and where new hair growth begins (hair bulb). Oil producing sebaceous gland is a part of hair follicle structure along with hair bulb. This helps lubricate hair and prevents it from getting dry and brittle.
Hair follicles are innate, we are all born with fixed number of hair follicles and no new hair follicles can be grown later in lifetime.
New hair growth means new hair shaft produced by the follicle.
This refers to Hair Cycle.
