Frequently Asked Questions
how long does rainbow henna last before fading?
Rainbow henna typically fades within 7 to 10 days, depending on hair care routines and environmental exposure. Frequent washing, chlorine, or UV light accelerate pigment loss, so limiting these factors can extend the vividness by a few days.
is indigo safe for sensitive skin?
Indigo is generally safe when diluted properly, but people with eczema or severe allergies should perform a patch test. Using a carrier oil and avoiding direct contact with the scalp can reduce irritation.
can I use rainbow henna on color‑treated hair?
Rainbow henna can be applied over previously dyed hair, but the existing pigments may alter the final shade. Test a small section first; the henna may layer, lighten, or mask prior colors depending on the base tone.
