Silicone-Lined 5mm Micro-Rings: These micro rings are used with our 1 gram i tip hair extensions. Aluminum micro links are known to be an essential tool for fitting individual stick-tip extensions, and also LA weaves and micro ring hair weft applications. Silicone micro rings are lined with an extra layer of silicone which helps eliminate hair shedding while providing support around hair cuticle shaft for extra grip. Micro beads allow more secure and gentle hold to any hair integration and can be adjusted or removed with ease.
