Hypertrophic Scar

Hypertrophic scar is a raised, firm area of scar tissue that develops when the body produces excess collagen while healing a wound, and it remains confined to the original injury site. These scars are typically red or pink, may be itchy or tender, and often become less pronounced over time; they are distinct from keloids, which extend beyond the wound margins.

On the scalp, a hypertrophic scar can result from surgery, trauma, or inflammation and may alter local hair growth or affect the outcome of hair restoration procedures; clinicians evaluate scar height, texture, and impact on surrounding tissue to guide care. Management ranges from conservative measures such as silicone sheets and corticosteroid injections to procedural options like laser therapy or surgical revision, and early treatment can reduce cosmetic impact and improve planning for any future hair procedures.
