How to color your hair with henna: here's how to dye your hair without having to resort to the classic dyes that contain ammonia.
Henna is obtained from the leaves of Lawsonia Inermis, a shrub with thorns with white-pink flowers. Already since ancient times it was highly appreciated for its coloring and fortifying properties on the hair. It is harmless on the skin and has a long lasting effect; penetrates inside the hair cuticles, without causing unwanted effects.
Unlike chemical dyes, it does not contain ammonia; anyone can use henna to dye their hair, even pregnant women, as long as it is a pure product.
The branches and leaves of lawsonia, dried and pulverized, are used in natural cosmetics by virtue of their coloring power, which allow particular and impressive shades of the base to the composition: from bright red to mahogany and black. The leaves release a deep red color, while the branches a color that goes to brown. This is why not all henna on the market color and dye the hair giving the same results.
Characteristics and Types of Henna
Pure henna contains only Lawsonia Inermis and other herbs; pay attention to the product you find on the market; some companies add the product with picramate, a synthetic dye that can cause allergies and skin irritations.
Compared to classic colors, henna does not damage the hair, on the contrary it strengthens it; it does not penetrate inside but binds to the keratin on the surface, thus making it thicker. The price changes according to the type of henna and brands, but generally does not exceed 6-7 euros per hectogram.
Types of Henna and Hair Yield
It should be noted that the only henna is the one obtained by drying the leaves and branches of Lawsonia Inermis. It releases an intense red color, more or less strong depending on the amount of branches or leaves present in the mixture.
Neutral henna does not release any type of color. It is used as a pack to strengthen the hair and stimulate its growth. This mixture is obtained by drying the leaves and branches of the Cassia Obovata.
The henna that releases the black color is obtained by drying Indigo, a plant mixed with henna in variable proportions. This combination, in fact, allows to obtain a dark color, tending to black. Like Lawsonia Inermis, it has stimulating and strengthening properties.
Blond henna is obtained from the mixture of several different herbs: chamomile, rhubarb with a small percentage of henna. The brown one, on the other hand, is obtained by combining together walnut husk, juniper berries and indigo.
