Henna (generic)

🌿 What is Henna (Generic)?

Henna is a natural dye made from the Lawsonia inermis plant and is traditionally used for hair coloring and temporary body art. While pure henna is typically plant-based, many commercial henna products include additional ingredients such as para-phenylenediamine (PPD), metallic salts, or preservatives. These added substances may contribute to irritation or sensitivity in certain individuals.

🤔 Why might a sensitivity to Henna occur?

A sensitivity to henna may occur for several reasons related to natural compounds or added ingredients:

• Lawsone dye reactivity – The natural pigment in henna may trigger discomfort or irritation in some individuals.

• PPD additives – “Black henna” or some commercial dyes may include PPD, a synthetic compound associated with higher sensitivity risk.

• Metallic salts or preservatives – Some henna mixtures include additional agents that may influence skin or scalp comfort.

• Detox pathway workload – Individual differences in how the body processes chemicals may influence overall tolerance.

• Immune sensitivity – Exposure to plant compounds or added chemicals may contribute to inflammatory-type reactions in sensitive individuals.

🛠️ What might I do about it?

🌱 Choose 100% pure henna with no additives
🧪 Perform a patch test before applying to skin or hair
🔍 Read ingredient labels closely, avoiding “black henna” or products with synthetic dyes
🧴 Apply soothing oils (like aloe vera or coconut oil) if mild irritation occurs
📆 Avoid henna for 8 weeks and observe changes in sensitivity

💊 Supportive General Supplements

• Vitamin C – Supports skin wellness and antioxidant balance.

• Glutathione – Supports detox pathways for environmental and chemical exposures.

• Quercetin – Supports balanced inflammatory and histamine responses.

• Omega-3 fatty acids – Support skin barrier wellness and help maintain inflammatory balance.

🌟 Why might a sensitivity to Henna occur but not with other hair dyes?

Sensitivity to henna may differ from reactions to other hair dyes for several reasons:

• Natural compound specificity – Some individuals respond uniquely to lawsone, the plant pigment in henna.

• Presence of additives – Many reactions attributed to henna relate to synthetic ingredients like PPD, not the plant itself.

• Metallic processing agents – Some henna-based dyes include metallic salts that differ from ingredients in standard dyes.

• Detox variability – The body may process plant-based or synthetic dye ingredients differently, influencing tolerance.
