PRF — Hair Regeneration

Platelet-rich fibrin (PRF) is prepared from your own blood and contains platelets and growth factors involved in tissue repair. When injected into the scalp, PRF may support hair follicle activity and improve hair density in selected patients, although clinical evidence remains limited.

Both PRF and PRP use components of your own blood. PRF is generally prepared without anticoagulants and forms a fibrin matrix that may support gradual growth-factor release. However, research has not established that PRF consistently produces better hair growth than PRP.

At Noir, we typically recommend an initial series of three PRF hair restoration treatments spaced 4–6 weeks apart. Additional maintenance sessions may be recommended depending on your response and type of hair loss.

Hair growth occurs gradually. Some patients may notice improvements in shedding or hair quality within a few months, while changes in density may take 3–6 months or longer. Results vary, and PRF does not work for every cause of hair loss.

PRF may be appropriate for patients experiencing certain types of early hair thinning, particularly when follicles remain active. We recommend evaluating the underlying cause of hair loss before treatment, since nutritional deficiencies, hormonal changes, and medical conditions may require different approaches.
