what is henna

Henna is a natural reddish-brown dye made from the dried, powdered leaves of the henna plant, Lawsonia inermis , used for coloring hair, staining skin in body art (mehndi), and even dyeing fabrics.

What exactly is henna?

• Henna is a plant-based dye derived from a small shrub that grows in hot climates such as North Africa, the Middle East, and parts of Asia.

• The leaves are dried, finely ground into a powder, and mixed with liquid (often water, lemon juice, or tea) to form a paste.

• The active coloring molecule, lawsone, binds to keratin in skin, hair, and nails, creating an orange to reddish-brown stain.

How is henna used?

• Body art (mehndi): Intricate designs are applied to hands and feet for weddings, festivals, and celebrations; the stain darkens over 1–2 days and usually lasts 1–3 weeks before fading with exfoliation.

• Hair dye: Henna coats the hair shaft, giving tones from coppery orange to reddish-brown, and is often used as a natural alternative to synthetic dyes.

• Other uses: Traditional use includes cooling the body when applied as a paste and sometimes dyeing materials like leather, wool, or silk.

Safety and “black henna”

• Natural henna paste is typically greenish-brown and gives an orange-to-brown stain, not pure black.

• So‑called “black henna” often contains added chemicals like PPD (a hair dye) to create a dark black stain, which can cause serious allergic reactions and skin damage.

• Safer practice: ask artists what ingredients are in their paste; reputable artists can list the simple, natural ingredients they use.

Cultural and modern context

• Henna has been used for thousands of years in Africa, the Middle East, and Asia, including ancient Egypt, for hair and body decoration.

• It appears across many cultures and religions (including Hinduism, Islam, and others) as a symbol of blessing, joy, protection, and good fortune at life events like weddings and births.

• Today, henna is also popular globally as a “temporary tattoo” trend, especially at festivals and on social media, even among people with no cultural background in its traditional use.

Quick FAQ style snapshot

• Is henna a real tattoo? No; it is a stain on the outer skin layers, not ink injected into the dermis like permanent tattoos.

• How long does it last on skin? Typically about 1–3 weeks, depending on skin type, placement, and aftercare.

• What color is natural henna? It stains in shades of orange to reddish-brown, darker on hands and feet where keratin is highest.
