HGFx3 is a complex patented by MartiDerm that consists of 3 Hair Growth Factors (Follistatin, IGF-1, VEGF) that are involved in controlling the hair growth cycle, ensuring a balance between the anagen phase and the telogen phase and favouring cell regeneration and repair.

3GF acts synergistically to activate, maintain and prolong the anagen phase. Follistatin is responsible for preventing the hair from entering the catagen phase, thus delaying hair loss; IGF-1 promotes cell survival, regeneration and proliferation, stimulating new hair growth and increasing hair density; and lastly, VEGF helps anchor the hair to the scalp and strengthens the hair fibre.
