A27 - Applying the SHR technique properly to remove hair...
I've seen a lot of videos, recently, where laser operators are showing their prowess with laser hair removal, usually with a diode laser. However, most of them are doing it wrong!!
They are usually seen 'scanning' up and down an area, relatively slowly, firing off a whole bunch of pulses of laser energy.
Unfortunately, this will most likely be pretty useless leading to hair regrowth and fine hairs replacing thicker ones. Plus, lots of excess treatment sessions...
So, what are they doing wrong?
The SHR Technique
This technique was originally developed by a laser doctor in Vancouver, Canada - Martin Braun - in 2009 to find a 'pain-free' way of treating hair using a diode laser at low fluence.
His technique (SHR is technique; NOT a technology!!) was to apply a sequence of 10 J/cm2 pulses at 10 shots per second in a relatively small area, approximately 10 x 10 cm, using a constant motion so that this area required between 6 and 10 passes.
This is an interesting approach because my calculations show that 10 J/cm2 is below the threshold fluence necessary to kill hair follicle germ cells. It's simply not enough energy! But,
