Can I use this shampoo if I have color-treated or chemically processed hair?

When using any shampoo with active scalp ingredients like birch tar and shungite on color-treated or chemically processed hair, it is important to manage expectations regarding color longevity. This product is primarily designed as a scalp-focused treatment to address dandruff, itchiness, and oil buildup. The cleansing mechanism, which supports the orderly shedding of built-up cells and removes excess sebum, can be more intensive than that of standard mild shampoos.

Birch tar is a potent natural ingredient that helps regulate the scalp environment, but its cleansing properties may accelerate the fading of hair color, particularly if you have recently dyed your hair or have delicate, porous strands. The formula does not explicitly state it is sulfate-free or color-safe, so it may strip color pigments more quickly than specialized color-care products. If maintaining vibrant color is your priority, you might consider using this shampoo only on the roots when necessary, or alternating it with a gentler, color-safe shampoo for the lengths of your hair. Always monitor how your specific hair type reacts, as individual results can vary based on the type of dye and hair condition.
