Antihistamines are primarily used to relieve symptoms of allergies, such as runny nose, itching, and sneezing, by blocking the action of histamine. The idea behind their use in hair loss, particularly androgenetic alopecia and alopecia areata, is based on their anti-inflammatory properties and the role of histamine in hair follicle regulation. Though not a primary treatment, antihistamines may support hair growth as an adjunct therapy, potentially benefiting both men and women by reducing scalp inflammation and stabilizing the hair follicle environment.

Each of these medications offers a unique mechanism of action with the potential for treating various forms of hair loss. Their off-label use requires careful consideration of the individual’s specific type of hair loss, overall health, and risk of side effects, emphasizing the importance of a personalized approach under the guidance of a healthcare professional.
