The researchers reported that follicular unit hair transplantation achieved a mean graft survival rate of 80.67% and significantly improved patient and observer satisfaction in individuals with stable cicatricial alopecia from postsurgical scalp scarring.

The study reported that using polyamide hair fiber implants may be an effective adjunctive treatment for scalp scars, with most patients experiencing no complications.

The technique effectively repairs skin after tumor removal, maintaining appearance and function without complications.

This study found that implanting polyamide hair fibers may serve as a supplementary treatment for scalp scars, with most cases showing favorable outcomes and manageable complications.

In this review, the authors summarize classical and recent insights into the biology and treatment of hypertrophic scars and keloids, concluding that while understanding and strategies have advanced, effective prevention and treatments remain unsatisfactory.
