henna will only show on white hair. no? lol.
plus, it stinks :x
Henna provide a naturaly highlight.
You can buy colored Henna but during the mixed instead of
adding water...you add regular Black Tea....(non sugar of
course)
Black Tea give you a darker Red tone....but you must leave the
Henna dye on your hair for 3 hours. do it twice a month and wash it
off.....
Eventually the Color of your hair look naturally shade under
sunlight. Your grey hair will be lighter red.
Why do you think Arab lady's hair does not look
black .....all because of Henna.
