Allergic reactions are a known side effect of Just for Men. The most common reaction is allergic contact dermatitis, which causes a rash. In rare cases, men have been hospitalized with severe allergic reactions.
“Just for Men” Allergic Reaction
Just for Men is known to cause skin irritation and allergic reactions in rare cases — even in men who have safely used it in the past. You should always do a skin-patch allergy test 48 hours before using Just for Men. The label includes instructions for this test, and warns about symptoms:
“Rapidly spreading skin rash, dizziness, faintness, difficulty breathing, shortness of breath, tightness of chest, hives or swelling to eyes/face, blistering of skin or scalp weeping, seek immediate medical attention.”
Just for men contains p-Phenylenediamine (PPD), one of the most common organic chemicals used in dark hair dyes. It has been on the market since the 1980s. Unfortunately, it is also one of the most common skin irritants. The North American Contact Dermatitis Society warns that it can cause reactions in 5-7% of the population.
Allergic Contact Dermatitis
Allergic contact dermatitis is an allergic reaction that occurs when an irritating substance on the skin causes redness, sores, and inflammation. The reaction may look similar to a chemical burn. Sensitivity to allergens can increase over time. In some cases, the allergic reaction only occurs after using “Just for Men” safely for years.
The most severe type of allergic reaction, anaphylaxis or “anaphylactic shock,” occurs when the immune system over-reacts and the entire body responds. It usually develops within a few minutes. If it causes severe swelling of the face, lips, tongue, or throat, anaphylaxis can be fatal within 15 minutes.

A severe allergic reaction is a medical emergency and you may need to be hospitalized. The first step is washing as much “Just for Men” off your skin as possible. If the reaction is mild, you may not need further treatment. In severe cases, a doctor may prescribe oral anti-histamine medications and anti-inflammatory corticosteroids.
