After continued use of henna, what type of effect does it have on the hair?

The use of henna on hair results in a build-up or progressive tints due to the way henna interacts with the hair structure. Henna is a natural dye derived from the leaves of the Lawsonia inermis plant and works by adhering to the keratin in the hair. Over time, with continued application, henna deposits layers of color, leading to a more intensified and richer hue. This build-up effect is especially notable as henna does not wash out like traditional hair dyes; instead, it creates a lasting impression on the hair.

The progressive tinting means that each successive application allows for deeper and more vibrant color, with the potential of the hair taking on darker or more pronounced shades. This characteristic is beneficial for individuals seeking to achieve a more defined color without the use of chemical dyes.

In contrast to temporary color, which fades with each wash, henna's effects are cumulative, contributing to the perception of a permanent change in hair color. Light strengthening and color fading options do not accurately capture the unique properties of henna, as it generally maintains its color integrity and can enhance the texture of the hair over time.
