Dihydroxyacetone, an effective ingredient for hair?

Dihydroxyacetone (DHA) is a coloring agent that is typically used in the composition of natural dyes, also referred to as non-oxidative dyes. Among other things, it helps to conceal the white hair that can appear over time.

As a reminder, traditional hair dyes, known as oxidative, color the hair by replacing its natural pigmentation. This type of dye acts on the hair's structure, as it penetrates the cuticles. This allows the hair's melanin to be replaced with the chosen color. However, it's worth noting that this type of dye can be harsh, hence the importance of using suitable care products (moisturizing and repairing) after its application.

Unlike traditional dyes, natural non-oxidizing dyes rich in DHA color hair without altering their structure. They act only on the surface, in contact with the keratins present on the hair fibers. Using this type of treatment allows the hair to maintain its shine because the keratin remains intact. Let's remember that keratin is a natural protein that acts as a protective barrier for hair fibers by forming the hydrolipidic film.

It's important to note that these act on a superficial level, DHA-based colorations are, however, temporary. To maintain the coloration, it is therefore necessary to space out shampoos and reapply the color a few weeks later. Moreover, prior preparation can help prolong the coloration. A scalp scrub is particularly necessary to remove dead cells and revitalize the hair. You can thus use our scalp scrub PHA 5% + jojoba beads beforehand. This pre-shampoo exfoliating gel gently removes dead cells for a healthy and balanced scalp.
