Because this product relies on plant powders rather than synthetic dyes, many people with reactive scalps tolerate it better than oxidative systems. However, natural does not mean risk-free: individual allergies to specific herbs (lawsonia, indigo, cassia, etc.) can occur. If you have a known history of contact dermatitis or a very reactive scalp, do a patch test 48 hours before full application — dab a small amount of prepared paste behind the ear or on the inner forearm and watch for redness, itching, or swelling. If you have recently used permanent colour, bleach, or a chemical perm, wait at least two weeks, preferably three to four, before applying henna. The mineral build-up from oxidative dyes can interact unpredictably with plant pigments, sometimes producing greenish or muddy tones. Conversely, if you plan to return to chemical colour after henna, inform your colourist; the herbal coating can resist or alter the uptake of oxidative dyes, and a clarifying or chelating pre-treatment may be needed. When in doubt, consult a dermatologist or trichologist, especially if you are pregnant, breastfeeding, or managing a chronic scalp condition.
