(2) Those with eyebrow area conditions like hemangiomas, sebaceous cysts, or seborrheic dermatitis.
(3) Individuals with keloid-prone skin.
(4) Those with mental or neurological disorders, or unrealistic/excessively high expectations for tattooing results.
(5) Individuals allergic to tattoo pigments.
(6) Patients with blood disorders like hemophilia or thrombocytopenia.
(7) Individuals with infectious diseases like hepatitis B should avoid eyebrow tattooing to prevent cross-infection.
