Easy Mehndi Ideas 4.0

What is mehndi?
Lawsonia inermis or the mignonette tree are different names for the same flowering plant called mehndi. The name 'mehndi' is derived from an Arabic name 'hinna'. The leaves of this plant are used to dye skin, fingernails, hair and even leather or wool since the Bronze Age. This form of tattoo art is used extensively during festivals and celebrations, especially during weddings. The leaves of mehndi when crushed do not stain the skin. They will stain only after the release of lawsone molecules present in the leaves, after smashing them with something mildly acidic liquid like tea. Thus, mehndi leaves are dried and ground into a powder to make a paste of toothpaste-like consistency. This paste is applied on the skin or hair for staining. This dye is completely natural and has no side effects. Side effects if any, arise only when natural mehndi is mixed with adulterants like carmine, pyrogallol, orange dye, chromium, silver nitrate, etc., that help in altering the effect of mehndi stain on skin.

How Does mehndi Work?
After the application of mehndi, the dye leaves a burgundy stain on the skin. The color of the stain depends on individual skin type and the amount of time that mehndi was allowed to stay on the skin. The color on the skin is due to the lawsone molecules present in the leaves. These lawsone molecules are more concentrated in the petioles of the leaves. As mentioned in the preceding paragraph, lawsone molecules are released only when the leaves are crushed with a mildly acidic liquid. Thus, many people trade mehndi in the form of powder that is made by drying, milling and shifting the leaves. When one needs to apply mehndi tattoos, the powder is mixed with lemon juice, tea or similar mildly acidic liquids. A thick paste is formed and used to apply intricate, detailed body designs. Few drops of essential oils like eucalyptus, Cajeput, lavender or tea tree are added to mehndi paste. These oils contain monoterpene alcohols that help in improving the staining characteristics.

Our skin is made up of a number of cell layers. The outermost layer of the skin is called stratum corneum. It helps keep away dirt and other infectious agents from the lower layers of the skin. This layer of skin is thick on certain parts of the body like palms and foot soles (especially the heels) and may be thinner on other parts like the ear skin. The stratum corneum is made up of keratin which also makes up for fingernails and hair. When mehndi is applied on your skin or hair, the lawsone molecule is small enough to penetrate the skin cell. It enters the columns of skin cells and does not bloat or spread out like a drop of ink would on a tissue paper. Thus, the stains remain sharp and clear, till the complete exfoliation of the upper layer of skin. mehndi stains darkest on the cells that are in close contact with the dye and the skin cells farthest from the dye have lighter shades.
