Henna Hair Color & Conditioner の説明 from Rainbow Research
Rainbow Henna Hair Color is 100% natural plant material - no additives, chemicals, preservatives, metallic salts or metals. Rainbow Henna coats the outside of each strand of hair. The shade of Henna is reflected through the hair while enhancing your hair's natural color. The cuticle is smoothed by Henna's sealing action, giving hair a polished look by making the light reflect off providing shine. Regular use of Henna can texturize the hair, giving it extra body - this becomes more evident with each application. Rainbow Henna color will last approximately 4 to 6 weeks but is safe to use more frequently.
Red Henna comes from small shrubs, called Lawsonia, that are native to the Middle East, West Asia, and North Africa. The leaves are dried and then pulverized into a fine powder. We also use the plants: Indigoferra, Cassia Obovata, Marigold & Chamomile Flowers to make the different shades. We choose the finest botanicals from around the world to be used.

Henna does not typically cause a reaction and does not contain any known allergens, if you have sensitive skin or chemical sensitivities a patch test on the skin is recommended before applying the full application.
