Keratin Extensions aka Fusion Hair Extensions are bonded to the natural hair. Aftercare for this method is a bit more detailed than others. The best advice I can give is to step away from high oil products. Oil and anything won't stick... if there happens to be an air bubble or slight gap between the keratin bond and the natural hair, oil from products can find a way between both and this enables slippage.
