Hi Joben,

The pulse width isn't the only setting parameter, there r fluence & repetition of the firing of laser pulses (Hz) in order to raise the temperature of hair shaft & the colourless follicle upto the degree that can coagulate them. Nothing beat the simple basic fact (scientific knowledge)

I know, but in your previous post you said "Longer pulse shouldn't be used for thinner hairs to prevent damage to adjacent tissue." If a machine has a fixed pulse width of 3-5ms (versus an adjustable pulse width) wouldn't that make the machine unsuitable for thinner hairs?

Hi Joben,

Since Fluence can't b compared among different brands of laser devices so some brands require only 3-5ms. Some brands required 60-80ms for lower fluence to work longer.

I read that post that you linked above and I agree with everything you wrote. The problem is finding a good laser tech that will actually use high enough settings. I've had LHR a few times and all but once I'm usually pleading with the tech to use more aggressive settings.

Good article Melb Aussie!

Although I've not had the opportunity, I've thought about the way therapists often combine electrolysis and laser: "laser first and then follow-up with electrolysis."

I'd do the reverse: One fast clearance with electrolysis (body hair with local anesthetic ... to go super-fast) and then, when the hairs return in a couple months (all in anagen); then laser.

In this way, the laser would be targeting only anagen hairs AND they would be nicely thinned-out (say at least 50% reduction) so that higher laser energy could be used without causing too much pain. I don't know if anyone has tried this; I would. (The "catch" of course is the requirement for a very fast body technique ... cleared-off in a couple day's work ... and local anesthetic.)

Honestly, if I found an electrologists who could work fast enough to do a body clearing in a few days with local anaesthetic, I would be continuing with that electrologist for subsequent clearings despite the higher cost and time commitment (in terms of hours spent with the electrologist).

At that point, I'd be too concerned about elongating the process by introducing laser. Even though the hairs treated would be anagen, a considerable amount probably wouldn't respond effectively to laser, but they would still shed from the follicle and I would have to wait for their cycle to return.

I might save money, but it would be at the cost of elongating the whole treatment by a year maybe. Perhaps my understanding is flawed, so please feel free to correct me.

I did laser first anyway, and now electrolysis, and I'm pleased with the results of both, and more so the results of electrolysis. I still have laser done on areas that I can't yet treat with electrolysis due to time and money. I doubt I'll receive any more permanent results from laser, but the temporary result is far better than waxing and the cost is about the same when considering I can wait longer between laser appointments.

Hi Joben,
Please note that the "rule of thumb" won't appear as soon as the laser beam/pulses hit you, but few minutes or longer after that => That's one of the reasons to do the test patching to find the right energy for different individuals.
Make sure you don't feel the heat (u may still feel warm a second or 2) as soon as the laser pulses moved away from that treated area. The heat should go away as soon as the pulse moved away from that treated spot => Otherwise burn.

To my dear & well respected Michael,
I'm looking towards for training until you have got better & gain back your health & strength. So that I'll trial & error your proposal.

Hi Scurvy, I'm working on it in order to gain faster speed with my Electrolysis Skills.

Might be up for some "experimentation" as my eye "sinks slowly in the West?" Got a client in Adelaide and Melbourne ... ready for the third pass (and the long flight over here). I'll do some emailing to the "dudes," ... "mates?" ... "blokes?"

Hairy backs ...

Eye surgery on Tuesday, if I don't chicken-out (I want to). A gross procedure with high risk. I mean, I'm happy to be a one-eyed pirate ("hee-yarrr"); but a one-eyed electrologist probably wouldn't be advisable. "Cyclops-electrology?" "the Braille Institute of hair removal?" Ugh!
