Hair Straightening:


Hair Straightening, also known as relaxing, is the opposite of perming.
You can straighten your hair chemically or you can do it with products
that temporarily tame the curls.
Hair straightening should always be performed by a professional.


Fine, lightened or colored hair requires a very mild relaxing formula.
Normal, medium-textured hair requires regular strength relaxers.
Coarse hair requires a strong or super relaxing formula.


Hair Straightening Technique & Tips:



• A hair relaxing formula is applied to the dry hair;

• The formula will be carefully combed through the hair;

• After 5 -8 minutes, the chemicals are completely rinsed
from the hair with warm water;
