The difference between current treatments on the market:

Sunliss Keratin

Treatments are formaldehyde-free

In the North American magazine “Allure”, an article was released on how many professional hair treatments being used in salons across the country contained high levels of formaldehyde. After countless tests, these treatments were said to cause “lasting hair damage”.

It was the desire of the Sunliss researchers to develop a hair treatment without using formaldehyde (or ingredients including formaldehyde).

The Sunliss keratin treatment line is a pioneer in the industry and is recognized for its research on formaldehyde-free products. Today Sunliss produces one of the most secure and advanced keratin treatments, certified by ANVISA.


A chemical straightener breaks the sulfur bonds in the hair and thus makes the hair straight. Chemical straighteners / relaxers are not good for the quality of your hair.

Juvexin is the active ingredient in a number of keratin products. These non permanent de-frizz treatments based on keratin do not change the structure of the hair. They care and nourish the hair inside out. However, treatments based on Juvexin are not straightening treatments or relaxers.
