Zero: the color that can be used for permanent or demi-permanent application  

Zero is the ammonia-free hair color from Salerm Cosmetics that unites the latest advances in color technology and a natural and sustainable approach. One of the great advances of this color system is that it can be applied as either a permanent or demi-permanent color, giving the stylist the versatility to achieve any result they can imagine. 

What is demi-permanent hair color? 

Demi-permanent hair color is one in which the color pigments do not reach the inside of the hair but are deposited on the most superficial layers without altering the hair structure. Demi-permanent color is a gentle system with which we seek a natural result and to revitalize and enhance. 

Differences between permanent and demi-permanent 

Unlike demi-permanent color, permanent color works within the deepest layers of the hair fiber to provide long-lasting color. In addition, permanent color is capable of stripping the hair of its natural color, modifying it permanently until the hair grows back or a new color service is carried out. 

How to apply a demi-permanent dye 

The Zero Color application process varies depending on whether it is applied as a permanent or demi-permanent color. For demi-permanent application, the dye must be mixed in a 1+2 ratio with the Aloe Vera Activator. This low volume developer is formulated with aloe vera and low-molecular-weight keratin to leave hair stronger after processing. 

How long does a demi-permanent color last? 

Although the demi-permanent dye offers a shorter duration than the permanent dye, some demi-permanent colorations, such as the Zero coloration, manage to keep the reflections alive for up to 4 weeks after its application and cover up to 70% of gray hair. 

When to apply permanent or demi-permanent color? 

If what we want is a lasting result or completely new look, permanent color is the product of choice. On the contrary, if we’re looking for a natural change and brighter color, we opt for demi-permanent color. 

The best demi-permanent dyes 

The best demi-permanent dyes are those that, in addition to depositing color, are formulated with ingredients that protect the hair fiber and care for the hair throughout the technical process. Zero hair color contains in its formula 7 of the best plant oils in the world. Each color has a specially selected range of oils chosen to achieve extraordinary benefits for hair. This, and also Zero’s advanced alkalizing system, capable of prolonging color duration and intensity, make it the best demi-permanent hair color on the market.
