I have 100% henna powder. How much alma powder do l add to the mixture for pepper and salt hair? Should l use coffee water to mix it?

For about 60g of henna, you can add a tablespoon of alma powder. What you must add to your henna paste depends on the shade you wish to attain on your salt and pepper hair. Plain water might give you a wine/orangish/regular red. Adding lime juice can give you a strawberry blonde. Coffee/black tea can boost the brown. Green tea is a very healthy option, too, and helps with hair loss. If you wish for an overall deep tint, soak your henna paste in an iron bowl. This helps henna oxidize to form a blackish pigment that cuts down on the red/orange and tends towards brown.
