Hair loss affects both men and women.

One of the probable causes might be a lipid called PGD2; which is thought to cause inhibition of hair growth in men and women. A topical lotion first used to treat diabetes in patients, is now being tested to treat hair loss in both men and women. It is currently in lotion form but a patent for the over- the-counter distribution, is currently in the works.  

Another drug with similar properties called the RT640 is also being tested.

This drug revives dormant hair follicle stem cells which promote hair growth. And just like any other drug or procedure, multiple uses will be required to see results.  Platelet Rich Plasma, originally created to heal wounds faster, is now being widely utilized as a way to treat hair loss in both men and women. Platelet Rich Plasma is blood that is taken from a patient, spun down in a centrifuge, and then red blood cells appear on the bottom while white blood cells remain on top. The white blood cells, containing the platelet rich plasma, are then extracted while the red blood cells get discarded. The PRP then is injected back into the patient via their scalp.

There is a type of PRP that might be more effective than others.

Platelet Rich Fibrin (PRF) goes through the same process as PRP except, during the spinning. In this process, PRF is spun in a much slower rate which retains more platelets and white blood cells. This results in the growth factors being released slowly and more effectively.

Since this process can be slightly invasive, the use of a distracting anesthetic device is used to curb any discomfort.

Three treatments are typically needed to see results of either procedure. However, results may vary since every individual is unique.
