What is the role of coherent laser light waves in a laser helmet?

Personally, I have seen the results of laser helmets, and I would gladly say that I am a fan of this procedure – you can continue you daily chores while wearing a comfy helmet and get the job done. There are some companies like Theradome that focus on coherent laser light waves in their helmets. I want to know if coherence in laser light actually matters during the procedure, and if it does, why don’t most laser helmet manufacturers boast it?
