Organic hair colour
I often have the same conversation with customers who are thinking about switching to a a natural herbal hair dye such as Henna, Indigo and Cassia.
1. Unlike conventional dye herbal colour has to be processed on the hair for a considerable amount of time, sometimes for a few hours for resistant greys. If you hair is fine and non resistant 1 hour might be enough however in most cases 4-10 hours will be needed to ensure solid coverage.
2. The dark hair which are not grey will stay pretty much the same depth as they were and the greys coloured with herbs will be lighter compared to natural hair and sometimes more translucent. However with subsequent applications in future they will darken.
If you do not like brassy shades that henna gives, you can use indigo with it BUT !!!!
3. YOU MUST KNOW that using indigo is a COMMITMENT. It is not the type of dye you can easily remove in future, so you need to say bye-bye to highlights. And only if you are happy with it you can proceed with the herbal dye.
4. Henna mixed with indigo will give you some red highlight when you are in the sun, it will always be a warmer shade of brown. If you really like cool shades then DOUBLE application will be required. First henna is applied, processed and washed out and then indigo is applied, processed for quite some time and washed out.
5. Cassia when used on its own washes out fast ( in 3 weeks) it is pale yellow in colour and is often used to dilute henna, or hendigo.
6. When cassia is mixed with a small amount of henna it can cover greys well and gives a beautiful strawberry blond to grey hair however if your hair is dark or dark blond cassia will not change their colour.
7. If your greys grow in patches you can have highlights done prior to dying hair with cassia to ensure even blond.
8. Lighter shades are better when you are trying to mask greys and they allow you more time between your colour appointments.
