Fake henna can cause permanent scars, warns Nigerian doctor

A prominent Nigerian health influencer, widely known as Aproko Doctor, has issued a stark warning about the dangers of using fake or black henna, cautioning that it can lead to severe skin reactions and permanent damage. Chinonso Egemba, the medical doctor behind the popular online persona, highlighted that some injuries sustained from these products could be lifelong.

There are some scars that may never leave for the rest of her life.

Egemba explained that natural henna, derived from the Lawsonia innum plant, yields a brownish, reddish, or orange tint and is considered safe for application. However, he identified the commonly used black henna as a dangerous imitation. This black variant does not contain natural henna but is instead mixed with paraphenylenediamine (PPD), a chemical also present in hair dyes.

There are two types of henna… the natural henna… It gives you a brownish, reddish, orange colour. That one is generally safe.

When PPD comes into contact with the skin, it can provoke an aggressive immune response known as allergic contact dermatitis. This reaction manifests as redness, swelling, itching, and pain, often following the pattern of the henna design. Egemba noted that reactions might be delayed in first-time users, appearing up to two weeks later, while those previously exposed could react within days.

If PPD touches your skin, your immune system can see it like a problem… that fight is causing all the redness, all the itching, all the swelling, all the pain.

Early warning signs include intense itching, burning sensations, and blistering. In severe cases, these blisters can break and leak, potentially leaving permanent scars or keloids, especially in individuals prone to such conditions. Egemba stressed that a very dark, black color is a significant red flag, as natural henna is never black. He advised immediate washing with soap and water and cold compresses for mild reactions, urging anyone experiencing severe symptoms like spreading blisters or breathing difficulties to seek urgent medical attention.

If the henna is very black… that is a red flag. Natural henna is never black.
