I’m not biased towards anything. I’m a consumer, so I have no reason to promote any one thing over the other. The only reason that I’m on this forum helping others is because I got great results with the help of other kind people on these forums when I was getting my treatments several years ago. Now, I just return the favor, for free. You would know this if you took a second to read my story which is clearly posted under my posts.
The fact that alexandrites are best is not my opinion. It’s a fact based on the specs of alex lasers, which make them most powerful. They have a shorter wavelength than diodes and Yags. The latter are made less powerful to cater to lighter skin types which alexandrites would burn at high enough settings to kill the hair. This is also described in the FAQs, which I wrote based on extensive research and opinions of many contributors here and on other forums who don’t regularly contribute here due to their other committments.
In the end, you can decide what is worth it to you and what’s not. We’re only here to provide facts. Diodes and Yags work too - there are just slight differences in results on certain types of skin types and hair types. There are many variables involved. In the end, the important things is that you’re being treated on the right type of hair by an experienced person who’s setting the BEST settings POSSIBLE in the situation given what they have. You can have ineffective treatments with an alex as well if settings are not right.
