The outcome of these experiments was analyzed statistically (taking into account the mean and the standard deviation of the number of replicates for the significance of the treatment effects within the confidence limits). See Table II for analysis of variance (ANOVA) data.

RESULTS AND DISCUSSION PROTEIN LOSS The process of cuticle chipping that results from abrasion of hair against objects such as grooming devices or even other hair is a major factor in hair damage. The proteins that constitute the cuticle cells are lost during wet combing. It is well known that wet
