One of the main dangers highlighted is the indiscriminate use of straightening and chemical relaxations, which have components that damage the structure of the hair.
According to Dr. Amanda, these processes that alter the structure of the hair, such as straightening, relaxing, perming, progressive and permanent brushing, can cause allergic reactions and harm hair health.

Additionally, salon hygiene is a crucial aspect to consider. Customers must ensure that the environment, including bathrooms, sheets, towels and objects, is properly sterilized.
Even brushes and scissors must be cleaned and disinfected between clients to avoid health risks.
Another point of concern is the use of formaldehyde in straightening products. Although formaldehyde can provide straight hair, it can also damage the structure of the hair, making it brittle and hard.
