The damaging effect of hair brushing was studied. The cuticle scales of the hair shaft were lifted away and stripped off by brushing the hair under experimental and practical conditions. Daily brushing was concluded to one of the most damaging factors of hair grooming; mechanical factors such as brushing and combing were the direct cause of damage to the hair. The degree of damage from brushing and combing was in direct proportion to the force which the hair underwent during brushing and combing, The number of damaged hairs was declined to less than one-tenth by the application of a hair conditioner, and reducing the brushing force. Improved brushing procedure and a special type of hair brush also reduced the undesirable friction and resulted in decreasimg damage to the hair.
