Japanese straightening is a permanent and totally irreversible straightening treatment. It is based on a chemical alteration of the structure of hair keratin and acts in a similar way to traditional perm liquid. It requires very careful application, so it is preferable to trust professionals to apply it, since due to its radical action, the slightest error produces irreversible damage to the appearance and quality of the hair. A permanent straightening is obtained, but it usually has a not very natural appearance and without any volume.
However, French straightening is the most innovative and avant-garde of straightening treatments and achieves a balance between the quality of the straightening, its duration, the hair treatment itself and the ease of its application. It does not chemically alter the internal structure of the keratin (as is the case with Japanese straightening) so its duration is not permanent, although it can last up to 6 months. Its application method is simple although laborious, it can take between 3 and 4 hours, so it is recommended to go to a professional hairdresser. The treatment is not aggressive and the hair also acquires shine, nutrition and straightening with immediate effects. The result is a very natural-looking straightening, and only a few minutes of blow-drying are necessary after each wash to give the hair the desired straight look. The prices of the service in professional hairdressers range from 60 to 180 euros.
