I wouldn't even bother with laser therapy, I've never seen any proof that it works.
Start by checking out the hairloss thread on the anabolic subsection, there is an abundance of good information there.
Also hairlosshelp and hairlosstalk are some good websites to get some hair loss feedback and treatment options.
If you really want to combat your hairloss, start with methods that are proven to work. 5% minioxidil, keto shampoo (regenepure DR, nizoral, etc), a DHT blocker like propecia (has the potential for serious sexual side effects) or a topical DHT blocking solution like s5 cream (no sides but is a pain to apply)
Good luck and long live your hairline
