Ouidad Q&A: Strand Test

Ouidad describes the strand test

Q: Is there such a thing as a "strand test" for breakage and hair strength?

Ouidad: Yes — the elasticity test. Healthy hair should be able to stretch up to 50% of its normal length without breaking. Dry hair will break quickly and will not stretch.
