    Foreword Kenya Bureau of Standards is a national standards body (NSB). The work of preparing Kenya Standards is normally carried out through national technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. National organizations, governmental and non-governmental, in liaison with KEBS, also take part in the work.

    Kenya Standards are drafted in accordance with the rules given in the KS ISO/IEC Directives, Part 2.

    The main task of technical committees is to prepare National Standards. Draft Kenya Standards adopted by the technical committees are circulated to the technical committee members for balloting. Publication as a Kenya Standard requires approval by at least 2/3 of the members casting a vote.

    Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. KEBS shall not be held responsible for identifying any or all such patent rights.

    This Kenya Standard was prepared by Technical Committee KEBS/TC 140, Beauty Services.

    A hair weave is human or artificial hair utilized for the integration with one's natural hair. Weaves can alter one's appearance for long or short periods of time by adding further hair to one's natural hair or by covering the natural hair all together with human or synthetic hairpieces. Weaving additional human or synthetic pieces can enhance one's hair by giving it volume, length and adding color without the damage of chemicals or adopting a different hair texture than that of their own. However, hair loss can occur either along the front hairline or above the ears due to the wearing of specific hair styles for a prolonged period of time, such as weaves. Such hair loss in known as traction alopecia. While the first edition was restrictive to synthetic hair, this edition expands the scope to include both the natural hair as well as natural human hair. Being a trade document, traders found it easy to circumvent the former edition hence sold synthetic hair extensions as natural human hair. The current edition takes cognizance of this and has included test methods to differentiate synthetic hair from natural human hair. In the development of this standard, assistance has been derived from

    US 1532, Synthetic Hair Extensions - Specification This assistance is hereby acknowledged.
