Sibel offers an extensive range, from accessories, to equipment, to large salon furniture items. Sibel's high quality pieces are durable and designed especially for use in a busy hairdressing salon. All Sibel training heads have had the following procedure - hair boiled in water for 6 hours then washed in clear water. Next it is placed in an acid bath for 5-20 minutes, then washed in sodium hydroxide to neutralise the acids. Afterwards, it is then washed in clear water and rinsed in a bath of peroxide with ammonia, and again washed in clear water. The hair is then shampooed, conditioned and air dried naturally. The Betty Training Head is made from 100% natural hair - chestnut colour. Maximum density: 230-260 hair per square cm.
