TLDR The scalp is usually protected from dermatitis but can react to hair products, especially tea tree oil and Minoxidil.
The scalp's thicker skin and abundant pilosebaceous units made it a strong barrier against contact dermatitis, often remaining unaffected even when the face, ears, and neck were involved. Scalp dermatitis was more commonly linked to "scalp-applied" irritants and allergens, with hair dyes, cleansing products, and medicaments accounting for nearly two-thirds of positive patch test reactions. The rinse-off or drip pattern sign helped identify scalp-applied allergens. Tea tree oil emerged as a frequent allergen, and Minoxidil was noted as a common cause of scalp dermatitis medicamentosa.
