Polydioxanone or PDO threads are a popular treatment option for facial rejuvenation and facial contouring.

PDO monofilaments are very thin threads made of this synthetic absorbable material. Embedding these threads into the scalp (Thread embedding therapy) has recently gained popularity as a treatment for hair loss and has shown promising results. The threads work on the same principle as dermaroller and microneedling. Controlled wounding of the skin causes increase in the circulation and release of growth factors around the hair follicles. It activates fibroblasts and elastin and also increases hair growth related gene expression

The results can be seen in 2-3 months after a single therapy
