This usually applies to people of African or Caribbean descent who have coarse and frizzy hair. The relaxer is a strong chemical substance that is applied to dry hair and then left on the hair anywhere from 15 to 45 minutes. The relaxer works chemically with the composition of your hair, weighing it down in certain areas and removing curls. Relaxers must be reapplied to new hair growth. These are better left for salons because this process is for people with a different type of hair characteristic of caucasians- straight hair with a smooth hair cuticle.
Straighteners too have to be reapplied with to new growth.
Once the hair is treated, to get the full effect of the straightener or relaxer, most people blow-dry their hair. After a few days or a week of blow-drying, the hair begins to dry out. The bergamot oil not only provides extra shine and protection to the hair cuticle, but it also doesn't leave behind a significant oily residue like a lot of other products do. Some companies may use this color to signify different added ingredients as well, but all in all, bergamot oil is among the most beneficial and inexpensive products. This works best if you part your hair into several sections to blow-dry.
