Final answer:
The type of hair color that involves a low-volume hydrogen peroxide and can only add tone or deposit color is semi-permanent hair color. It lasts for about 4 to 6 weeks and does not lighten the hair like permanent coloring does.
Step-by-step explanation:
The type of hair color that uses a low-volume hydrogen peroxide and can only deposit color or add tone to the hair, without lightening it, would be semi-permanent hair color. Semi-permanent dyes do not require the use of high-volume peroxide or ammonia, which means they cannot lighten the hair as permanent dyes can. Instead, semi-permanent coloring only coats the hair shaft and changes the tone rather than the color itself, which is why the result tends to fade after several washes, typically lasting for about 4 to 6 weeks.
It's important to note that permanent hair coloring is different as it involves a chemical process that removes the natural color of the hair and deposits new color. This process uses higher concentrations of peroxide to initiate the chemical reaction necessary for color change. The natural color is removed, and synthetic color is placed in the cuticle of the hair. Over time, all pigments wash out of the cuticle, with natural color fading slower compared to artificial dyes.
