Years ago, we as MD's were very frustrated when a patient came in because of hair loss. Options were limited and balding was inevitable as the patient often had to watch the hair go down the drain forever.
The GREAT news today for patients with this condition is: Hair loss is optional.
When it comes to reversing thinning/ shedding hair, we have had very good results with the infrared light therapy called Luce. Luce will not create a new hair follicle, but if caught early, can turn the weak hair that is on it's way out back to a strong growing hair.
Some other modalities that can help reduce shedding would be Rogaine and or Propecia. These also seem to boost the strength of Luce when used together.
It's important to find out why you are shedding.
There is a genetic test called Hair DX that can shed some light on whether the hair loss is genetic in nature. (male/female pattern baldness)
