Tattoos: are they compatible with hair colouring?
Transient/temporary black henna tattoos:
You may have become sensitive to PPD (a substance called paraphenylenediamine contained in black henna tattoo). We recommend carrying out a skin test behind the ears or on your wrist before applying on your hair.
Over the past few years, an important number of allergic reactions have been attributed to hair colouring. In fact, these allergic reactions come from an excess amount of PPD contained in black henna tattoos (that is often not actually henna).
PPD is also an ingredient of hair colouring, but at a much smaller and legal dose.
If you have developed an allergic reaction due to an exposure to high doses of PPD on your skin, when applying a black henna tattoo, this can lead to future sensitivity to PPD.
If you have experienced this type of symptom, we recommend consulting a dermatologist.
Garnier’s hair colouring products strictly comply with legal requirements when it comes to their ingredients.
