Summary
Henna, a natural hair dye, is generally safe but can cause rare allergic reactions. This case highlights allergic contact dermatitis from henna in a non-professional user.
Area of Science:
- Dermatology
- Allergology
- Cosmetic Science
Background:
- Vegetable dyes, like henna, are alternatives to oxidative dyes for patients with sensitivities due to lower allergenic potential.
- Henna is a widely used natural reddish-brown hair dye globally.
- While various henna-related pathologies exist, allergic contact dermatitis is exceptionally uncommon.
Observation:
- A 30-year-old woman presented with symptoms of allergic contact dermatitis.
- The patient had recently applied henna hair dye.
- The patient was not occupationally exposed to the dye.
Findings:
- The case confirms that allergic contact dermatitis can occur from henna application.
- This incidence is rare, even in individuals without professional dye handling experience.
- Suggests individual hypersensitivity to henna components.
Implications:
- Henna, despite its natural origin, can be an allergen.
- Clinicians should consider henna as a potential cause of contact dermatitis, even in non-occupational settings.
- Further research into henna's allergenic components and prevalence is warranted.

Overview
01:26Physical Properties of Amines
Amines with low molecular weight are usually gaseous at room temperature, while those with high molecular weight are liquid or solids in nature. Usually, low molecular weight amines have a rotten fish-like smell. Diamines typically have a pungent smell. For instance, cadaverine and putrescine, depicted in Figure 1, are two molecules responsible for decaying tissue.
01:29Hypersensitivity Reactions: Delayed Hypersensitivity Reactions
Delayed-Type Hypersensitivity (DTH), or Type IV hypersensitivity, is a cell-mediated immune response. It occurs when T cells, rather than antibodies, mediate a reaction to specific antigens. It is characterized by a delayed onset (1-2 days) and involves the recruitment of macrophages to the inflammation site.The initiation of a DTH response begins with the sensitization of T cells. During this phase, which lasts at least 1-2 weeks, antigen-specific T cells are activated, clonally expanded, and...
