Detailed answer

Hair and scalp glomus tumors are benign vascular tumors that originate from the glomus bodies in the skin. They are unrelated to allergic reactions to skincare products. Allergies to skincare products typically manifest as skin irritations, redness, itching, or rashes. Glomus tumors, on the other hand, are caused by an overgrowth of the glomus cells. These tumors are typically small, slow-growing, and appear as bluish or reddish bumps under the skin. The exact cause of glomus tumors is not fully understood, but they are not associated with allergies to skincare products. If you suspect a hair or scalp issue, it is best to consult a dermatologist for a proper evaluation and diagnosis.
