What Wavelength of Laser or IPL Should Be Used?

What wavelength or setting of IPL or laser can I use to shrink my hair follicles? I don't want to remove my hair but just make it grow finer. If theoretically, most of the hair is in anagen?

It is important that the following are present for best results:

2. longer wavelength- NdYag Diode to reach deep enouugh to damage living portion of follicle

3. Adequate training and knowlege of laser operator.

Wavelength for thinning hair

The ideal wavelength for hair reduction is between 695nm-810nm.  You can't "shrink" the follicles and cause them to grow in thinner, but by removing about 15-20% of the total hair in any given area per treatment, what grows back will appear thinner.
