PDOgro™ Polydioxanone Thread Procedure For Hair Regrowth

[original article Oct 3, 2018, updated Oct 4, 2025]

Hair Restoration Physician Dr. Alan J. Bauman is the first to use PDO Polydioxanone Threads PDOgro™ Procedure for Hair Regrowth in the U.S.

PDOgro™ Procedure using Polydioxanone Threads for Hair Regrowth – PDO is a known absorbable FDA-cleared synthetic suture and surgical scaffold material that stimulates endogenous collagen production, elastin, hyaluronic acid, as well as activates fibroblasts. PDO (polydioxanone) threads have been used in aesthetic medicine for years for rejuvenation of skin, skin tightening, skin lifting, and wrinkle reduction. Hair regrowth in patients with hair loss from androgenetic alopecia has been observed in patients with PDO threads inserted into their scalps. Mechanistic studies on mice suggest that upregulation of growth factors responsible for stimulating hair follicle activation may be responsible for the improved hair growth noticed in patients.

In this video, you see ABHRS-certified hair restoration surgeon, Dr. Alan Bauman, performing the final step of his proprietary PDOgro™ process using polydioxanone threads in the thinning crown area of a hair loss patient, “C.T.”  Continued research will help determine how long the results of PDO threads last and which candidates are likely to have the best hair regrowth effects. The non-surgical application of PDO threads into the scalp is a relatively safe and comfortable outpatient procedure with no downtime or aftercare. The PDOgro procedure using polydioxanone for hair regrowth may help prevent or reduce the need for hair transplantation. They may also be used for stopping, slowing, or reversing hair loss in conjunction with other treatments such as minoxidil, finasteride, low-level laser therapy, PRP platelet-rich plasma, and other cell therapy treatments. Dr. Bauman recommends that HairCheck hair regrowth measurements be performed every three months (90 days) to track the improvements in hair growth from treatment and to help determine when the subsequent PDOgro thread treatment for hair regrowth is indicated.

PDOgro™ with and without PRP: Before & After Results Photos

Clinical trials are now underway at Bauman Medical to determine how long the hair growth improvements with PDOgro threads will last as a stand-alone treatment, as well as with the addition of PRP at the time of insertion. In the patients below, the results were already beginning to become visible to the naked eye at around 12 weeks (3 months). Female patient “M.M.” had PDOgro threads inserted at the hairline, right, and left temple area, with no PRP or other hair growth treatment. Female patient “C.T.” had PDOgro threads inserted in the crown/vertex area with no PRP or other hair growth treatment. Male patient R.H. had PDOgro (PDO+PRP) performed live by Dr. Alan Bauman at the prestigious South Beach Symposium for Aesthetic Dermatology in Miami in 2019, along with NO other hair growth treatment. His remarkable results are seen beginning at just three months post-treatment, with continued improvement through 9 months post-treatment.  Stay tuned for more updates soon!
