The effect of grooming on the hair cuticle
A study has been carried out on the effects of normal grooming on the cuticle of human hair. The grooming processes studied included shampooing, wet combing, wet brushing, and towel drying.The experiments were carried out on tresses of hair and and also included "on-head" studies. The results were examined using scanning electron microscopy techniques. The data indicate that all the damage normally observed can be entirely due to the grooming process. Shampooing and towel drying were shown to inflict some damage, but the process of wet combing or brushing greatly increased the damage. Brushing was shown to be more damaging than combing. The use of conditioner was shown to significantly decrease the damage by reducing the friction forces generated in the hair during combing.
