Can I use this paste if I have dyed or chemically treated hair? — Sulsen dandruff paste for all hair types, 100 ml "AromaSaules"

The active ingredients, particularly salicylic acid, may have a slight drying effect or could potentially interact with hair dye. It's generally wise to perform a patch test on a small, inconspicuous section of your scalp before full application, especially if you have recently colored your hair or have sensitive, damaged skin.

To minimize any impact on color, ensure the paste is applied only to the scalp and not massaged through the lengths of your hair. Rinse thoroughly with cool water. If your hair is already dry or fragile at the lengths, using a conditioner or hair mask on the mid-lengths and ends after rinsing out the paste can help maintain moisture balance. The paste is formulated for scalp care, so focusing application there helps target flaking and oiliness without unnecessarily affecting your hair's color or condition.
