Detailed answer

Hair and scalp fibrofolliculomas are benign growths that develop within the hair follicles. They are not caused by allergies to skincare products. Allergies can cause various skin reactions such as rashes, itching, or dermatitis, but they do not lead to the formation of fibrofolliculomas. The exact cause of fibrofolliculomas is unknown, but they are believed to be associated with genetic factors. Typically, fibrofolliculomas are harmless and do not require treatment unless they cause discomfort or affect the person's appearance. If you have concerns about hair and scalp issues, it is recommended to consult with a dermatologist for accurate diagnosis and appropriate treatment options.
