Hair Growth & Shedding
Anagen is the growth phase that lasts between two and eight years. In this phase the growth cells in the papilla rapidlydivide and produce the hair shaft which becomes keratinized as it pushes up and out of the hair follicle into the pore. The hair follicle grown down into the skin to get nourishment
Catagen lasts between two and four weeks and this is consider the transitional phase. This is part of the renewal process where the hair follicle is degraded and the hair stopa growing but does not fall out. During this phase the hair follicle shrinks to about 1/6 of the normal length. The lower part is destroyed, the dermal papilla breaksaway and the buld detaches fromthe blood supply and the hair shaft. It is then pushed up as the hair follicle disintegrates.
Telogen is the hair follicle then goes into the telogen or resting phase for two to four months, during this time the hair still does not grow but remains attached to the hair follicle while the dermal papilla is in a resting phase. Keep in mind that over 15 percent of all hairs are in this phase at one time.
After the telogen phase the cycle is complete and the hair goes back into Anagen phase. When the hair follicle starts growing a new hair it has to first get rid of the old hair wich is still attached to the hair follicle.
When there are to many hair follicles you will notice alot of hair falling out, this is called shedding and also what causes it. Instead of the hair falling out one by one it falls out all at once, making you believe that your hair is falling out.
Keep in mind that if your scalp is red, very itchy, or if there are bumps, blisters etc this is not normal. I will discuss this further in a latr article.
Every situation is different, and I am only writing on my experiences through friends, family and hair clients. I also so alot of research and read alot before writing any article. Thank you all for your questions, if you have any concerns or questions leave a comments or email me firstname.lastname@example.org
