Before BKT
After
While it is less damaging than traditional relaxers or straighteners, BKT is not without risks. The formula does contain formaldehyde, a known carcinogen that can irritate the eyes and lungs. Frankel said her eyes burned and she broke out in hives the first time she had it done in a poorly ventilated room.
In the October issue of Allure, they tested the chemicals used in Brazilian straightening and found they contain a much higher level of formaldehyde than is considered safe by OSHA. Safe levels are under 0.2 ppm, levels in the straightening solutions are upwards of 3 ppm. They notified the FDA of their results, and the FDA replied that they will investigate.
Kids should not be around when this service is being done. Pregnant or nursing women cannot get the treatment done.
It can cause color to fade. Frankel gets her hair colored several shades darker than she likes it before getting the treatment.
