Micro bead hair extensions! Microbead, or micro ring or "cold fusion" (because no heat is used) are applied using tiny beads (2.6-3.0mm in diameter) to attach the extensions without using heat, glues, or sewing. The beads are pinched very flat and are nearly undetectable.
Hair extensions at a professional salon typically cost $200 to $600 depending on the type. Clip-in and tape-in hair extensions cost around $200, while sew-in, glued-in, fusion, and micro-bead extensions range from $300 to $600.
