Nadra Mehndi Powder appears to be a brand of henna powder and pre-made henna cones, primarily sold in Pakistan and by retailers specializing in South Asian and Middle Eastern products. Here's what the available information indicates about the product:

Product and Ingredients:

Nadra Henna Powder: This is a key product, often described as a fine-textured, triple-sifted powder that is 100% natural and pure. It is a traditional mehndi (henna) powder used for both body art and hair coloring.

Nadra Henna Cones: The brand also produces pre-made cones, which are often marketed as "Urgent" or "Emergency" cones, suggesting a fast-acting dye. The ingredients listed for these cones typically include "natural henna, oil, preservatives colour & distilled water.

"Natural Colour" (Red/Orange): The powder and some cones are meant to produce the classic reddish-orange henna stain.

Important Health and Safety Considerations:

It is crucial to differentiate between natural henna and "black henna" or other synthetic dyes, as they can have very different effects.

Natural Henna (Lawsonia inermis): Pure henna powder is generally considered safe for most adults when used on the skin or hair. However, it can cause skin inflammation (dermatitis), redness, itching, and swelling in rare cases of allergic reactions.

"Black Henna" and Pre-mixed Cones: Many "emergency" or pre-mixed henna cones, especially those that promise a very dark or "black" stain, can be dangerous. These products often contain an ingredient called p-phenylenediamine (PPD), which is not found in natural henna. PPD can cause severe allergic reactions, including chemical burns, permanent scarring, and lifelong sensitization to PPD and related chemicals.

Nadra "Urgent Cone" warning: While some Nadra products claim to be "natural," the existence of an "Urgent Cone" product and the general warnings about pre-mixed cones from India and Pakistan suggest caution. Natural henna paste is perishable and cannot be stored on shelves for long periods. A paste that is shelf-stable for an extended time almost certainly contains chemical additives.

Side Effects of Frequent Use: Even pure, natural henna can have side effects with frequent use on hair. It can lead to excessive dryness, a change in hair texture (becoming coarser), and, for some, scalp sensitivity.
