Chemical changes permanent, Japanese relaxers, discolorations and this type of aggressive treatments Hairdressing use chemicals that can cause hair structure ceases to be compact and become porous, which would lead to dehydration and, therefore, loss of elasticity. Consequence? dry, fragile, brittle and alterations in texture hair. Impair the appearance of hair, but also accelerate its fall.
Rosalia Gozalo, member of Dermopharmacy the COF of Madrid , also warns that these techniques can cause hair salon skin problems, such as allergic reactions, irritation, burning and scalp burns . In fact, if a person has sensitive scalp and uses a dye or permanent may experience irritative dermatitis, usually accompanied by itching and flaking, which needs to be diagnosed by a dermatologist, said Modesta Cassinello, pharmaceutical of Pharmacy Modest in Granada .

Those responsible for these problems are the substances used. While both experts recognize that the methods have evolved and improved over time, no longer compounds capable of altering the capillary structure.
“Permanent solutions used ammonium thioglycolate. Keratin, basic chemical used for permanent straightening, contains formaldehyde, a carcinogenic and toxic by inhalation substance and can cause respiratory disease “Gozalo explained.
” These agents may act on the color and shape of the hair fiber. Chemical injuries are multiple , “says Amalia Lopez, product manager René Furterer . “The dye up the scales of the cuticle to allow the color to penetrate the cortex of the hair -more- which can cause embrittlement of the fiber. Straightening, and other permanent desencrespado can change the internal structure of hair (breaking the disulfide bonds), which degrades the cuticle and damage hair. “
For its power before performing any of these methods, vocal recommended to ensure that the hair is healthy and know the degree of aggressiveness of each of the techniques.
Hairs should not undergo these treatments
Cassinello advised not to undergo these techniques hairdressing people with any of these characteristics:
-those who have altered scalp (irritation and high sensitivity).
– Suffering hair loss and do not have good control.
– If previously made hairdressing aggressive treatment.
– People with very bleached hair that are not well maintained.
– people who are not willing to take care of hair later.
HAIR CARE SUBSEQUENT
To alleviate this damage to the hair, after care are essential. “The gestures of everyday life contribute to altered assaulted hair. Amplified oxidation, they accelerate the degradation, color blur and off. It should be avoided in products with alcohols and the silicone composition as it dries the hair fiber “Lopez explained.
It should repair and hydrate with shampoos, conditioners and formulated specifically for the aftercare aggressive treatment masks.
A shampoo too corrosive to many detergents, diffuses the nuances and highlighting of the hair. Eventually, it shuts down and loses its brightness. Therefore, ” it is very important to use a very soft base with an acid pH to tighten the hair scales and preserve the color hue” says the product manager René Furterer.
“The hair balsam coated cuticle cohesion and return favor impermeability and resistance” details Gozalo. “If hair is severely damaged -more- resort to a mask (you can use daily) and serum and reparative oils that help restore the hair fiber. Not to forget the specific treatments for the care of the tips, which are suffering the most. “
“The use of these hair cosmetics, in addition to getting reduce the harmful effects of these methods, help keep hair clean, healthy, shiny and smooth,” says Casinello.
Other tips include avoiding the pharmaceutical use of hairdryers and irons and avoid mechanical damage such as sudden brushings or too tight ponytails.
In the case of Japanese straightening must avoid shampoos containing many salts and avoid dipping the hair in salt water three to four days after treatment as sodium chloride tends to sweep the chemical smoothing.
“Fortunately, these treatments only damage the hair, not the hair follicle, so hair grows when the consequences of the treatments are not visible in the new hair,” says the expert Rene Furterer.
