benefits for EcoSmooth™ Silk vs. Silicone

• Each panelist evaluates 1-2 sets of hair tresses and are asked which they prefer (comb

and feel).

• It is a single blind study – panelists do not know which tresses are treated with which

formulation.

• Separate tresses are used for wet and dry hair evaluations.

• Dry hair panelists – also asked which tress has more volume.

• Dry hair tresses air dried.

• Minimum of 10 evaluations needed.

Panel Studies - Procedure

• Minimum of 10 evaluations needed.

• 80% preference is considered statistically significant for a forced choice test.
