Cassia Obovata strengthens, cleanses, conditions, adds shine and protects your hair from the elements. It won't color dark hair tones but can yield a light golden tone on grey and blonde hair. Cassia can be used in all Ayurvedic DIY hair masks and also with henna. When cassia is mixed with henna to dye hair, it can yield a range of tones such as strawberry blonde and rich copper.
