Hair Dyes

Henna hair dye is 100% natural and safe to use. Henna as a base provides all the requirements of hair dye and in addition, offers all its natural properties including hair conditioning while leaving the hair soft. Henna hair dye will also slowly fade away to your hair's original color, but will not leave any lines or stripes like synthetic dye.

Also henna does not contain bio-available lead acetate, which can be harmful. Henna dyes coats each hair shaft with a natural, semi-permanent protein called hennatannic acid. Heat causes the hennatannic acid to cling to the proteins found in the hair.

Because henna coats and seals the hair shaft, it helps protect the hair from damaging effects of sun, salt, chlorine, wind and pollution in the environment. Rather than producing dramatic color changes, henna dye enhances and deepens existing color. Because the color from henna is transparent, it cannot lighten dark hair; it will, however, add highlights to dark hair and can darken the color of lighter hair.

There are mixed reactions about hair dyes some studies have linked hair dyes with a higher risk of certain cancers, while other studies have not been able to establish the link.

Most hair-dyes don't have to go through safety testing that other cosmetic color additives do. When hair dyes were first manufactured, the main ingredient in coal-tar hair dyes causes allergic reactions in some people, but now most of them are made from petroleum sources.

After applying hair dye, don't leave the dye on your head any longer than needed and rinse your scalp thoroughly with water after use. It's not a good idea to dye your eyelashes and eyebrows because allergic reactions to the dye can cause swelling or increase the risk of infection in the eye area.

This poisoning is from exposure to a hair dye or tint. Consumers considering changing their hair color have a choice of coloring agents to use. There are at least four basic categories of products: Temporary hair colors are applied in the form of rinses, gels, mousses and sprays Semi-permanent dyes penetrate into the hair shaft and do not rinse off with water like temporary colorings.

Permanent dyes require more work to apply, but the hair color lasts until the new hair - "roots" - grows in. Because permanent dyes contain hydrogen peroxide, they cover gray hair more effectively and can be used to lighten hair color, unlike other dyes.

To apply permanent dyes, the user mixes together a hydrogen peroxide liquid with another liquid, works the mixture into the hair, and after about half an hour rinses the dye out with water. Consequently, permanent dyes generally cannot be washed out with shampoo, although repeated shampooing may reduce the color over time.

Gradual or progressive dyes are dyes in the form of a rinse that slightly darken hair by binding to compounds on the hair's surface. Gradual dyes are usually applied daily until a dark enough shade is achieved, after which it may be used less often to maintain the color.
