Skin Biopsy is a procedure in which a small sample of skin tissue is removed for examination and analysis. It is performed to diagnose or evaluate various skin conditions, such as skin cancers, rashes, infections, autoimmune disorders, and other skin abnormalities.

Hair Biopsies are less common but may be performed in specific cases. Hair biopsies involve removing a small section of the scalp or hair follicles for examination. They are typically used to evaluate conditions such as hair loss (alopecia), scalp infections, or suspected hair shaft abnormalities.

Both skin and hair biopsies are important diagnostic tools in dermatology. They help in accurately diagnosing skin and hair conditions, guiding appropriate treatment plans, and providing valuable insights into the underlying causes and characteristics of the diseases or abnormalities.
