Redseal Hairstyling License Practice Test

What method is used for hair straightening that involves both thio relaxer and flat ironing?

1. Chemical perming

2. Base relaxers

3. Thermal reconditioning

4. Sodium hydroxide relaxers

The correct answer is: Base relaxers

The method that involves both thio relaxer and flat ironing is thermal reconditioning. This technique combines the use of a thio relaxer, which chemically alters the hair structure to relax curls and waves, with the use of heat from a flat iron to lock in the straightened style. Understanding this method requires recognizing the role of thio relaxers in hair care. Thio relaxers use a chemical process to break down the disulfide bonds in hair, allowing it to take on a straighter form. However, for the new straight style to be effectively established and maintained, the application of heat from a flat iron is crucial. The heat effectively seals the hair's cuticle, resulting in a smoother and straighter appearance that lasts longer. The other options listed do not accurately describe the method that incorporates both thio relaxers and flat ironing. Therefore, recognizing thermal reconditioning as the correct answer hinges on understanding the processes of relaxing and straightening hair effectively through both chemical and thermal means.
