KeraDyn™ HH - Hair Dynamics Test
You Can Tell Hair is Healthy by the Way it Moves
The Hair Dynamics Test is a unique method of evaluation designed by Croda in conjunction with the Centre of Visual Computing at the University of Bradford, UK. The test digitally records hair motion using a high definition video camera. Hair tresses attached to a sliding bar are moved horizontally back and forth at a set speed. The key parameter measured is the maximum swing height of the tresses.
The following hair types were tested using the Hair Dynamics Test. Tresses treated with KeraDyn HH appear on the right hand side of the videos:
Bleached European Hair
The swing height of the hair tresses treated with the leading conditioner increased by 2.7 times compared to the untreated tresses, whereas the swing height of the tresses treated with the KeraDyn HH conditioner increased by 4.5 times.
Chemically Straightened Latin American Hair
Treatment of relaxer damaged hair tresses with a conditioner containing KeraDyn HH generates hair that swings twice as high as the untreated hair tress.
Coloured Asian Hair
The swing height of the coloured Asian hair was 24% lower than virgin Asian hair. Following a conditioning treatment containing KeraDyn HH, the swing height increased to only 2% lower than virgin Asian Hair. The swing height of the tress treated with KeraDyn HH was 1.3 times higher than the untreated coloured tress.
