How do you not damage your hair when straightening it?

Permanent smoothing is a trend that never goes out of style and always remains valid especially in women who have frizz or bristly hairs and prefer a neater look. By doing this treatment at least three times a year, the hair suffers a lot of mistreatment with the chemicals that can later lead to even worse problems.

It is necessary to know the effects of straightening on the hair and the ways to avoid the greatest possible damage so that the hair always looks healthy and shiny.

There are various types of chemical treatments that are done in hairdressing salons or even applied at home to straighten the hair permanently or semi permanently. None of them is natural because they apply chemicals in the hair fiber and their procedures are very similar. All damage the hair in some way and this is where you have to pay attention to minimize this consequence.

The hair changes in its structure each time it is subjected to a chemical to smooth it. Its structure is formed by three parts, the cuticle, the cortex and the medulla. The most extensive part is the cortex that is made up of proteins and to be able to smooth the hair it is always necessary to alter it. In addition this is done at least every six months since the smoothing requires that the new root does not look wavy.

The first softens and reduces the waves in the hair and its intensity is not so high but in turn is the least aggressive option.  The use of formaldehyde for the smoothing treatment is not recommended, since its use in excess is toxic and causes dermatitis.

The formaldehyde process cannot and should not be used as a smoothing type. It is prohibited anywhere in the world because the concentrations needed to straighten hair is toxic to humans.

Its use produces severe alterations of the respiratory tract nose, mucous membranes, throat, trachea and lung. It damages the sight, reddening the eyes and their tissues, leaving a blurred vision. It hurts the skin, irritating it generating dermatitis.

Before choosing the smoothing style, some factors should be taken into account:

The characteristics of each hair, if it is thin, abundant, if it is porous, if it is mistreated, if it was chemically treated with discolorations, etc. All this will determine the exposure time of the hair to the chemicals and the way to apply them.

Special care should be taken if the hair is very long and the ends are damaged or if it is dyed since the condition may worsen. It is preferable in this case to cut a little.

No straightening should be done on bleached hair, with highlights or lighting, or if it is treated with henna or metallic salts.

A virgin hair of chemical treatments can better resist the smoothing process since this is more resistant, while a treated hair of physical form (planchitas, dryers, etc.) or chemical (dyes, smoothing, etc.) decreases its resistance.

All the treatment must be done by a qualified professional and in a reliable place. The professional should wear gloves and the place should have good ventilation since the odors of the chemicals are very strong.Before performing the procedure, chemical tolerance tests should be done on a hair and on the skin to avoid allergies or reactions especially with sensitive skin.

The straightening damages the external and internal structure of the hair, weakening its structural proteins to acquire a different form to what is genetically predisposed.

This process reduces the resistance of the hair, which gradually loses mass and becomes finer at the tips through the usual treatments such as washing, combing, drying and modeling.

The straightening produces a weakening of the hair, although it is seen as soft, strong and bright, inside it is much less resistant so you have to take care of it in the following days.

If a non alkaline straightening is done, the hair should not be touched in a couple of days, so that the oxidation is as good as possible.

Use special products for damaged hair such as shampoo, conditioners, combs and moisturizing masks. Avoid using appliances such as the dryer, the iron or curling iron, as they mistreat the hair more. Comb gently and take care of hair from the sun or the wind.
