Damaged hair, here are the causes
The root causes of brittle hair can be of different nature:
- internal causes : improper nutrition, psychological stress, hormonal disorders, etc .;
- external causes : excessive exposure to the sun, air pollution, too aggressive and repeated cosmetic treatments, using plates, etc.
Obviously these factors can intervene together, and sometimes they are unavoidable, as unfortunately in the case of pollution.
In addition, we must take into account the genetic differences that make some people's hair weaker than others.
Fine hair, therefore less strong and resistant, tends to become brittle more easily, because it has a much more fragile keratin structure.
For their part, however, dry hair, deprived for example of the lubricating and protective action of the sebum, is more easily damaged by external agents and consequently is necessarily brittle hair.
Even the famous "split ends" they can be considered a type of brittle hair whose stem deterioration is manifested by a split in their terminal part (the ends).
Physiological analysis of brittle hair
To understand how the hair deterioration process takes place, it is necessary to examine its structure.
The horizontal section of a hair shows its composition in three concentric layers: medulla, cortex and cuticle.
There cuticle , the outermost layer, is made up of keratin flakes superimposed like roof tiles, forming a compact and resistant armor that serves to protect the hair from external chemical and environmental agents.
In the brittle hair , analyzed under a microscope, the cuticle is absent.
Without this external protective layer, the hair becomes thinner, becoming more fragile, facilitating the deterioration of the keratin structure (compact microfilaments) that makes up the cortex.
In these conditions, any aggressive cosmetic treatment damages the cohesion and compactness of the cortex, making the hair brittle and prone to breakage, with a greater risk of falling out.
The brittle hair in man
Damaged hair needs special care and precautions to protect it from external causes that could cause it keep hurting them .
It is not enough just to use any shampoo to keep them clean, because very often choosing the wrong detergent can even make the situation worse.
What can cause brittle hair in men?
For example, the intake of steroids by athletes can lead to brittle hair and in fact, as we have seen, hormonal ones are among the causes of weak and brittle hair.
Emotional stress also worsens the condition of our hair, because the production of adrenaline is increased in the body which causes damage to the hair follicle which will produce weaker and brittle hair.
However, there is a solution to intervene on this problem, and it is certainly good to act when you realize that the hair has lost its tone and shine.
So let's see what can be valid remedies for brittle hair.
