How long does a skin biopsy on the scalp take to heal if a scab is formed?

A skin biopsy on the scalp typically takes about 1 to 2 weeks to heal if a scab forms. The scab usually falls off as new skin forms underneath, and complete healing may take a little longer depending on individual factors such as skin type and overall health. It's important to keep the area clean and avoid picking at the scab to prevent infection and scarring. Always follow your healthcare provider's aftercare instructions for optimal healing.
