Cassia obovata is just like henna but has a different light golden dye molecule which gives a lovely lustre to pale coloured hair.
This certified organic fine cassia powder from Rajasthan:
Gives you soft, shiny and healthy looking hair
Improves the look of damaged hair (e.g. bleached, heat damaged) bu making it look thick and silky
Adds a beautiful golden sheen to dull or grey blonde hair
Cassia can help to bring out the brightness of hennaed hair, or help to gain different colours when used with henna
Cassia won't make your hair lighter, if your hair is darker than pale blonde, but it will improve the texture and condition.
