While some growth factors are known to inhibit hair growth such as TGF beta, the majority of growth factors like platelet derived growth factor PDGF are essential to epidermis-follicle interaction and the dermal mechenchyme interaction required for hair canal formation and growth of the dermal mesenchyme. Additionally, vascular endothelial growth factor VEGF improves follicle visualization promoting hair growth and increases follicle and hair size. Below is a drawing of Vascular Endothelial Growth Factor.

The best way to evaluate a patient is to arrange a personal, in-depth consultation. However, this is impossible for many patients who fly in from other parts of the country or world. For this reason we have developed the remote consultation package, which is an acceptable alternative to the in-person personal consult.
Once your photos and questionnaire are reviewed, we will telephone you to discuss your questions or concerns regarding the procedure. You will also be given a suggested treatment plan and the costs involved. Click here for more complete information on our free on-line hair restoration consultation process.
