We know that split ends are more likely to occur in weathered and oxidized hair. But, split ends happen when the cuticle is removed (damaged) and the cortex-cortex CMC serves as a route for the propagation of axial splits in the fiber, leading to the formation of cracks and split ends. Hair strength depends on cuticle integrity and amount of water in the fibers, conditions that are related to chemical damage. Chemical damage by bleaches, dyes, straighteners and even sunlight can weaken hair and increase inter-fiber friction, leading to breakage. An important factor involved in hair breakage is the occurrence of tangles created by combing forces. Where the break occurs along the fiber, correspond to the point of higher combing forces. The type of fracture depends on hair condition and wet versus dry combing or brushing. Combing dry hair is more related to short segment breaks, and wet combing is related to long segment breaks. The short segment breaks are more related to split ends. Straight to wavy hair combed dry, produces higher end pick forces than mid-length forces, but when wet, produces higher mid-length combing forces corresponding to where hair breaks and to the amount of breakage. The work of combing highly coiled hair is lower wet than dry. The reverse holds for wavy to straight hair. Split ends form more readily from the abrasion (friction) in combination with torsional deformations (grooming and styling). Splitting occur when the cuticle is damaged and weakened. Crack is formed in the cortex. Few cuticle layers do not hold the ends of the hair fiber together. Also, highly oxidized cortex cell membrane by free radical chemistry is more susceptible to split. Hair treated with free radical cosmetics and exposed to sunlight is susceptible to splitting.[5,8,38]

The use of formaldehyde formulations became very popular since 2003, and the first country to start this practice was Brazil in Rio de Janeiro. The most used products, a decade ago, were based on a solution or cream containing a home-made formaldehyde formulation obtained from a mixture of conditioners, hydrolized protein and a 37% formaldehyde solution, easily obtained as an over-the-counter substance, sold in every drugstore in Brazil. The formaldehyde solution was commonly used to sterilize medical materials and hospitals, and easy to find in every drugstore. The practice soon became so popular that called attention of the health vigilance organizations in Brazil (ANVISA) that prohibited the use of any product containing formaldehyde in concentrations above 0.2% for cosmetics and 5% for nail polish. Afterward, the formaldehyde was replaced by a potentially 10 times more mutagenic and the neurotoxic product belonging to the same aldehyde group: The glutaraldehyde. Easily obtained from hospitals and clinics, glutaraldehyde was commonly used as a sterilizer. It was soon not a home-made product anymore, but a demi-industrialized nonlegal substance, commercialized in every salon in Brazil. The solutions came in beautiful colored bottles of 500 ml to 1 liter. The label carried a false ANVISA registration number, and the product was sold to the salons by door-to-door sellers.[54,55,56,57]
Shrestha et al. found that children prenatally exposed to formaldehyde, polycyclic aromatic hydrocarbons, perchloroethylene, or acetaldehyde in the third trimester had an increased odds of Wilms' tumor per interquartile increase in concentration. Couto found a relationship between pregnancy, maternal exposure to hair dyes and hair straightening cosmetics, with and early age leukemia. Mazzei et al. analysed home made hair straightening products containing formaldehyde and verified that the antibacterial activity was detected in all creams with positive mutagenicity induction. They concluded that the creams showed an intense genotoxic response.
Galiotte et al. in a study evaluated the genotoxic risk to 69 female hairdressers exposed daily to chemical substances such as hair dyes, waving and straightening preparations and manicurists' products by the Comet assay test (single-cell gel electrophoresis) The hairdressers showed a higher frequency of DNA damage that could be associated with the hairdressers' occupational environment, where different chemicals are chronically manipulated and inhaled. Considering that this profession in many countries, including Brazil, is not officially regulated, it is not discarded that the use of BKT may have some influence in the data of this work.

Robbins returned to Seattle where growing numbers of the long-haired counterculture tribe were gathering and gaining the attention of the mainstream (or "straight") culture which was increasingly mystified, and affronted.
