PRP hair therapy, also known as platelet-rich plasma therapy, is an injectable treatment that uses platelet-rich plasma obtained from the patient’s own blood. After injection, platelets release growth factors and other biologically active molecules that support tissue repair and regeneration.
In trichology, PRP therapy is used to support hair follicles, reduce hair loss, and gradually restore density. The procedure may be recommended for androgenetic alopecia and other forms of hair thinning after medical assessment and identification of the underlying cause.
The procedure begins with a small sample of venous blood. The blood is then placed in a centrifuge, where platelet-rich plasma is separated from the other components.
The prepared plasma is injected directly into the scalp using fine needles, with particular attention to areas of reduced density. Once injected, the platelets release growth factors involved in cellular signaling, tissue repair, and processes associated with hair follicle function.
The procedure usually takes approximately 30–60 minutes. Temporary sensitivity, redness, or mild swelling of the scalp may occur after the injections and typically resolves on its own.
PRP therapy supports hair follicle activity, helps reduce shedding, and maintain hair density.
A course of treatments is designed to increase hair density in areas of thinning. Changes develop gradually in line with the natural hair growth cycle, so results are assessed over time, usually within several months.
Growth factors released by platelets are involved in biological processes associated with follicle function and tissue repair. PRP helps create a more favorable environment for maintaining existing hair and supporting healthy growth.
Hair loss can have different underlying causes, which is why PRP therapy is prescribed following a medical consultation. For androgenetic alopecia, nutritional deficiencies, and other forms of hair thinning, the procedure may be combined with medical, injectable, or other therapies when clinically indicated.
