The chemical wave allows hair to keep any form for a long time. Its essence is always identical: hair impregnate with chemical composition and wind on hair curlers or hair curlers. Processing allow to enshrine by fixer hair in the new provision. Depending on the applied means distinguish several types of chemical wave.
One of the oldest ways of hairdressing – acid is still popular and does not hand over positions. It is one of the most resistant waves which keeps on hair more than 6 months. The chemical medicines used for it get in hair and create quite rigid curl. The acid wave does not suit owners of soft and fine hair as they stretch at root and do not hold form. Hair after the procedure quite often become brittle and dry.
The alkaline wave keeps only 3 months, but has softer impact on hair. Curls look naturally, are rather elastic. Alkaline medicine gets in hair and at the same time opens its external scales (unlike acid). For hard straight hair this procedure can be almost useless – in month the hair are straightened.
The acid wave on the basis of thioglycolic acid can be done even on dyed hair as she quite softly acts. But such chemistry keeps only one or one and a half months. One of modern ways of wave uniting the first two types – neutral. Allantoin thanks to which hair do not dry is part of means. Acid RN of medicine is balanced therefore is suitable for all types of hair, influences them softly and carefully. Nevertheless, the hairstyle turns out quite resistant. To minimize negative impact of chemical wave, use amino-acid wave. Proteins which treat are its part besides amino acids and feed hair therefore curls turn out gentle, soft and natural. However such wave is not suitable for hard, long and heavy hair. One of the most sparing, but effective waves – silk wave. Silk proteins are part of medicines, they even improve structure of hair and look after him. Even the painted and decoloured hair become more dense and live. Such wave will hold on two-three months. One more effective treating way – biowave. As a part of medicine ammonia, hydrogen peroxide, thioglycolic acid are replaced more sparing bio-elements, similar to molecules of hair. It is possible to carry such popular types to biowave as Italian on the basis of bamboo extract, Curls of angel, with use of botanical complex.
