Has anyone tried low-level light therapy?

I have androgenic alopecia and finally visited a trichologist today. The good news is my hair follicles are still present and treatment could work.....So they recommended a combination of low-level light therapy and minoxidil. I've done a lot of online research into LLLT, however it's hard to know what reviews are reliable or fake and I'd want to be certain as it's expensive!

Has anyone her tried it? Was it worth it or should I just try minoxidil?
