Copper Tubes / locks
Copper tubes are smaller than micro rings, creating a more discreet bond. This technique uses the same method as micro rings, but the tips of the hair extension strands are smaller, lying subtly in your hair. A section of your natural hair is placed into the copper tube with a tiny tip extension strand. They are then clamped together to hold the hair in place, using no glue and causing no damage to your natural hair. It is possible to go up to 3 months without a maintenance with copper tubes!
