HAIR'S POROSITY and COLOR DEPOSIT

As hair damage (porosity) increases, so does hair's ability to "grab" color

deposit darker and deeper than expected. Remember: Even "virgin hair"

can be porous due to sun and/or environmental exposure. And, bleached

hair, being very porous, accepts demi-color deeper than the shade description

noted on the container.

Experienced salon colorists know that demi-permanent hair color is designed

to DEPOSIT both level and tone.. without lightening pigmented hair. These

shades color gray hair to the level and tone printed on the color's container.

So, a level 6 golden shade will cover gray to a level 6... and can also affect

the current shade of the hair which is still pigmented... and, the more porous

or damaged or chemically treated the hair is, the deeper the pigmented hair

will appear.

When we "play it safe" by selecting a no-lift demi-permanent hair color shade

which is 1 - 2 levels lighter than the result we desire, we can create gorgeous ,

modern shade-on-shade gray coverage, as we infuse rich, yet controlled color

enhancement on the hair which has not yet turned gray.
