You should really try to talk to the actual person who will be doing your treatments. It’s impossible to get a sense of whether they know what they’re doing if you’re not really sure what you’re looking for yourself and aren’t asking the right questions.
I would recommend for you to print both the FAQs and the Questions to Ask at Consultation forms at the links below and read them carefully before your next appt.
FAQs clearly state that alex is more powerful and more effective. They also state that effectiveness will depend on the coarseness of the hair and the settings used, NOT where it’s located. And finally, you’d get better results with someone treating with a diode if the person using the diode knows how to use it and the person using the alex doesn’t. That’s why experience and expertise is VERY important. That’s what you’re looking for at the consultations. Not necessarily how swanky the place is. You need to find someone who knows what they’re doing with the laser that they have.
You’ll get results from 3 treatments, but you’ll need a total of 6-8 to kill hair in every hair cycle and even close to 10 on your face. This is also in the FAQs. You would do yourself a disservice by not reading them carefully to learn exactly what you need to be looking for. When you go for consultations, it would help to ask for settings they will be using to judge whether they will not be undertreating you for example. It would also help to ask if they’ve treated male faces in the past.
