Growth Factor Concentrate (GFC) for hair refers to a treatment that utilizes growth factors to promote hair growth and improve the overall health of the hair follicles. Growth factors are naturally occurring proteins that play a vital role in cell growth, development, and tissue repair.

In the context of hair, Growth Factor Concentrate typically involves the use of Platelet-Rich Plasma (PRP), which is a concentrated solution of growth factors derived from the patient's own blood. 

Growth Factor Concentrate treatments for hair are often used for individuals experiencing hair thinning, hair loss (alopecia), or those seeking to improve the quality and thickness of their hair. The treatment is typically performed as a series of sessions, spaced a few weeks apart, to achieve optimal results.
