I think you should see this more like climbing a hill
like most new to DIY - especially when you see how daunting the task is
- you are wanting to get up the hill quick treat a hair once and then - I WILL NEVER HAVE TO TREAT THAT ONE AGAIN
- the trouble is this is often what leads to overtreament and potential scaring and yes pros make the same mistake usually because their client wants to see some progress for their money - then complain that they have 'hardly done anything'
slow thermolysis takes a moment so timing is important unless you machine is flash or has a timer built in that cuts the current automatically - so a get loudly ticking old fashioned clock is advisable
i think youd be better with the softly softly catchy monkey analogy
(as we are talking about monkeys
see my assistant hes a very good impressionist :xP
walk up the hill slowly stop take a look at the view maybe even go back down a mile and pick a flower then walk back up again - enjoy the hill breath the air take your time - if you rush you could trip and fracture your skull - or run out of food because you have not prepared beforehand - not enough needles - poor hygiene routines and so on - no clock.
half way up you may slip and slid back down a 100 ft and think 'dammit' i was here a week ago now i have to do that all over again
tut do you climb or give up
this is just like life nothing comes easy - so go easy - expect some regrowth - and then treat lightly again - remember compared to say a laser (even this slow set up - you own the machine remember so time and money is now no longer an issue)relies on pigment to carry temperature a bit like wearing black tshirt in the hot sun or solar panels on your house - you are eliminating all the variables when using a needle as the hair irrelevant as the needle is sitting right on the bulb - when you tweeze a regular untreated hair just look how small that is and put your needle next to it - it slowly dawns on you that this great big machine and handset and needle and heat - and there is this tiny little dot - softly softly catchy monkey
if you get regrowth - so what - wait a few weeks and zap it again
don't worry be happy - eeeeeeeeeasyeeeeeee mon
