Keratin Bond questions
What does keratin bond mean?
A bond made from a keratin-based polymer, pre-tipped on each strand and softened with heat to wrap around a small section of natural hair.
Can I wear high ponytails?
Yes. Because strands move individually, keratin bonds are the most updo-friendly semi-permanent method.
Is the hair reusable?
Usually not. New strands are applied at each full refit.
How long does application take?
Three to five hours for a full head, depending on the number of strands.
