"Weak Spot" BAMBOO HAIR (Hair Shaft Defect)

Have you ever been told you have this by a hair stylist? I have, and if your anything like me I always wonder what exactly causes a "weak spot", and what cant be done about it. In this journey of mine about my hair, I have been to dermatologist, I have been to "hair doctors", I have just about purchased every product know to man to help me retain some length. In all those woes I have learned that less is better, and some things are just genetic.
So in doing some research, I stumbled across a term BAMBOO HAIR. I had never heard about it, but once I started reading it I wonder if I and MANY other ladies and gents on this HAIR JOURNEY could possibly have this disorder. Bamboo Hair, aka trichorrhexis invaginata is a hair disorder that many of African ancestry find themselves battling. Here is some info I found on the net about the subject:

"Bamboo hair, also known as trichorrhexis invaginata, is very distinctive. The hair fibers have the shape of bamboo. Instead of being smooth along their length, the fibers have focal nodules that make the fiber look like bamboo. The nodules are focal defects in the fiber where a cup and ball shape has developed. The hair closest to the scalp forms a bulge with a cup shape form in which the hair fiber further away from the scalp sits. These defects are weak spots in the hair that are easily broken. The piece of hair that sits in the cup shape gets pulled out leaving the exposed socket. This is now called a golf tee hair because of its shape".

"Bamboo hair is often seen along side other hair fibers the have focal twists in them. These twists, called torsion nodes, create stress on the chemical bonds in the hair and are also weak points where hair fiber is liable to break if pulled.
These bamboo hairs and golf tee hairs can occasionally develop in normal hair from over processing but more likely trichorrhexis invaginata is a congenital defect often a symptom of another disease. Netherton's syndrome is a disease that can involve bamboo hair as well as ichthyosis and atopy. Netherton's syndrome is usually evident from birth with flaking skin, red rashes and sparse hair growth involving fragile bamboo hair.
Netherton's syndrome is probably the result of an autosomal recessive gene expression. The gene seems to be involved in keratinization of the hair cortex. Examination of hair fibers has shown that the cuticle is normal but the internal cortex is not completely keratinized at sporadic points along its length. These incompletely keratinized areas are soft and weak and the hard, fully keratinized portions of the fiber become impacted into the soft portion creating the cup and socket structure. The improperly keratinized areas of the hair fiber can also become twisted making torsion nodes.
Bamboo hair often improves spontaneously as the individual grows. Most treatments involve preventative measures to avoid over processing and physical manipulation. Several treatments are available to remedy skin problems that develop in ichthyosis and Netherton's syndrome and these may also help improve hair quality".

Im sharing this bit of info with my followers, because I know that knowledge is power! Lack of knowledge can cost you ALOT of PAIN and MONEY!! Especially for us as African American/Black females. The Black haircare market is a billion dollar industry, and think we can spare ourselves ALOT of doe if we know what might be at the ROOT (pun intended) of our hair woes.
