Our client had bought the clip on hair entensions with code TR3A8 (see the product here ) wanted then to place permanently. Also had changed the color of her hair to more beige blonde and had done and brown highlights.
What we did is:
1) to separate the weft with clips in 3 different pieces
2) remove the clips,
3) to dye the three pieces in beige blonde (from Beige Ash)
4) to make chestnut brown highlights and
5) to place permanently 3 pieces with micro rings (the advantage of fitting micro rings is that you do not need glue or high temperatures and so your own hair is not in danger at all).
