During a Brazilian hair treatment, dyeing of the human hair extensions is sometimes resorted to. This means that the hair extensions attached through this means of Brazilian hair treatment are prone to fading over a period of time. This process of fading is accelerated by extraneous factors such s improper care, pollution, spending more time outdoors in the sun or in water, etc. Even the best dyes are prone to fading over time. Due to this, minor shade differences between the hair strands when the Brazilian hair treatment was initially carried out, get exacerbated over time. Further, some minute shades such as reds and ashes disappear completely and become bland. This is a major disincentive for clients of Brazilian hair treatment who demand these bright colors. In order to cope with this gradual fading of colors, hair stylists store a sample of the original colors when carrying out the Brazilian hair treatment, to help them match the fading strands against the original and take corrective action. The shade difference in individual strands may be very minor, but its impact on a full head of hair is drastic. For this reason, you should approach reputed professionals and salons when getting a Brazilian hair treatment done. These professionals can offer to maintain a color ring and samples of original colors.
