Chenice uses a pure Keratin to create the perfect size and shape bead that is invisible. The Keratin does not harm the hair and can be removed with Multi Vitamin Solution. The Keratin comes in a block form and is heated in an appropriate heater. Do not re heat the keratin. Break off what you need and then clean the heater. Use Pure Sheen in the water to keep your fingers from getting sticky. Lightly powder beads when finished to prevent sticking. Small sections of hair can be applied as a full look or for more thickness and body.
