Scalp threading, particularly using polydioxanone (PDO) threads, is an emerging non-surgical treatment for hair restoration. This technique involves inserting fine, absorbable threads into the scalp to stimulate hair growth by improving blood flow, enhancing tissue oxygenation, and triggering collagen production. The PDO threads act by creating a chronic micro-trauma, which consistently promotes the body’s natural healing processes, leading to the regeneration of hair follicles and new hair growth over time.

The procedure is minimally invasive, typically involving the use of local anesthesia to ensure patient comfort, and has minimal downtime. Patients can often return to their normal activities shortly after the treatment. The threads dissolve naturally within six months, but their effects on hair growth can continue for several months as the body continues to repair and regenerate the treated areas.
