Detailed answer

Hair and scalp pilomatricomas are benign tumors that originate from hair follicles. They are not caused by allergies to skincare products. Allergies to skincare products typically manifest as skin rashes, itching, or redness. Pilomatricomas, on the other hand, develop due to mutations in hair follicle cells. These mutations cause the cells to divide rapidly and form a tumor. The exact cause of pilomatricomas is still uncertain, but it is not related to allergies or skincare products. If you suspect a pilomatricoma, it is important to consult a dermatologist for proper diagnosis and treatment.
