These extensions have a great technique which we use with double wefts hair or just single extensions. This method has micro rings which has the extension attached to it which then gets clamped to your natural hair, without the use of adhesives or heat. The micro ring has a silicone coating on the inside of the ring which is what attaches the extension to your hair. The method DOES NOT damage or weaken your hair. Last up to 3 months. We recommend a visit back to us after six weeks to make sure you are happy and for us to check the extensions and discuss your after care routine. If the extensions have been looked after properly then a percentage can be reused. Reapplications are cost effective and a lower charge will be given on second application.
