Henna
It is prepared by shredding the leaves of the Lawsonia Inermis shrub and is used as a natural dye. It can also be used to cover gray hair.
Mix 200 ml of water with 75 grams of henna (increase the amount if you have very long hair).
Apply to all hair and leave on for a few minutes. Finally, wash your hair normally.
Ivy extract
Ivy leaves are excellent for blocking gray hair. From them you get a very dark colored extract, ideal for covering gray hair.
Simmer 45 grams of ivy leaves in a liter of water. Once the leaves have softened, remove from the stove, let cool and drain.
Apply to all hair at least 3 times a week.
