Cassia obovata (Senna italica) is a plant that contains a faint golden or slight yellow dye. It is also known also as “neutral henna” or “senna obovata.”

Cassia is used to condition and thicken the hair and it is used to dye blonde hair which is turning grey, to bring out the golden highlights.

Cassia obovata is safe to use on over relaxed, bleached and dyed hair and can last anytime from a few shampoos to permanently.
