When using henna the kits are often sold with questionable oil mixes.
Henna Caravan is dedicated to using safe natural products and we sell kits with lavender oil because it is so wonderful and safe.
Often the liquid mix sold with kits is not safe and can cause skin rash.
You can mix with water or lemon juice and add the safe oils to have a great fun activity.

The biggest danger with skin problems and scars is from PPD fake black products sold as henna. THis is horribel and here is a link to photos of someone who used the PPD on the hair,
