The Damage Hair: Types, Causes and Effects

The Damage Hair: Types, Causes and Effects

Damaged hair is caused as a result of a combination of abuse over time. The cuticle suffers wear: the gradual erosion of the cuticle of the hair strand. This exposes the cortex, which slowly degrades. Finally visible damage, including hair breakage occurs.

Another indication of damaged hair are split ends. Typical split ends start when large areas of the cuticle separate and expose the cortex. A crack starts to open the strand and, if the damage is severe, the crust explodes outside the damaged hair.
Now that you know the symptoms of damaged hair, knows the types of damage and how to prevent and restore the health of your hair!


  • Chemical Damage


All types of chemical treatments like dyeing, highlights, lights or reflections, straightening, keratin, permanent, among many others, dry the hair and alter its natural structure. They are wonderful because they allow us to change our look and hairstyle, but at the same time very harmful to the health of hair.

Chemical treatments for straightening and permanent change the shape of hair due to containing agents, which first break the sulfur bonds that give hair its structure. Then, it gives the hair a new way and neutralized. This is the term assigned to the restructuring of the chemical bonds in their new positions, the process that permanently fixes the hair in its new form. Remarkably, this process eliminates the protective layer of the cuticle (responsible for gloss and texture) and the ability to retain moisture (hydration) hair.

Dyes and permanent dyes cause the same to the protective layer of the cuticle damage since it is removed so that the color to penetrate, causing the cortex is exposed. The hair is very fragile, brittle and dull or tenderness (because fat is what provides this benefit lipids).

Dyeing, which can also cause damaged hair, changes the structure to penetrate the cuticle to enter the cortex, which damages the fat layer.


  • Environmental damage


Constant exposure to elements like the sea (salt) pool (chlorine and ozone) and pollution also affect the cuticle. Sunlight ultraviolet cuticle affects similarly to fading, and eventually disintegrates the hair keratin protein. This causes light switches and dry hair. This is particularly problematic for hair dyeing which may be compromised. If you plan to spend time at the beach or out in the sun for an extended period, a hat is a great way to protect hair.

  • Thermal damage


In the case of iron, hair dryer and curling iron or curling iron, excessive heat can also break the protective layer, exposing the cortex and the inner layers of the strands. When this occurs, the hair loses its ability to retain its natural proteins and vitamins, because it is no longer sealed. This deficiency in the protective layer and the action of heat in the nucleus of the cell can cause the hair boils and bubbles are formed in the heat softened hair.

To protect against the effects of excessive heat during drying or styling your hair, remember to always use a termoprotetor treatment which will form a protective shield over the strands avoiding the disruption and loss of the protective layer of keratin, the restoration and maintenance of hydration.

Minimize use of heat on the hair and configure thermal styling tools at the lowest possible temperature will work very well to keep your hair soft and healthy.

  • Mechanical friction or damage


The hair is naturally quite robust and can withstand the onslaught largely hairstyles, but still brushing and combing can end damage, especially if wet or tangled. Be especially careful with metal combs as with hairstyles shakes (to give hair volume), since pulling the scales of the cuticle and can cause harm. If delicate cuticle scales are raised can be released next time a comb passes over them.


It is much easier to treat hair before damage to treat damaged hair. Unfortunately, once the cuticle is significantly damaged, its structure cannot be repaired by 100%. In this case your best weapon is the conditioner. The internal structure of the hair depends on strong sulfur bonds and weaker hydrogen bonds. Without sufficient moisture, can reduce the number of hydrogen bonds. Of conditioner allows the restoration of hydrogen bonds and improves the moisture content of damaged hair by increasing the waterproofing cuticle.
