Our hair grows on average 1/2 inch a month. That is only 6 inches a year.
It grows the fastest at the age of 15-30 and slows down when we hit 50 years of age.
At the age of 35 is when we have the maximum amount of hair density.
The Dermal Papilla at the base of the hair provides nutrients & oxygen to make a protein called keratin. The Papilla tells the hair when to grow, rest and fall out.
Anagen - Growing stage that lasts 2-6 years. This is determined by your Genetics.
Catagen - Resting stage that lasts 1-2 weeks.
Telogen - Falling out stage that lasts 100 days (3 months)
We lose an average of 25-75 hairs per day. This is NORMAL hair shedding. *So if you wash your hair every 3 days, it is normal to see an increase of hair coming out on wash days.
If you start shedding more hair than normal than this might be a Hair loss condition called Telogen Effluvium (TE). Click here to read my article on TE.
