Will acupuncture work for head ache?

Hi friends, I am new here. Last day, I met a lady who is specialized in acupuncture treatment. I met her at a wedding event. During the event, I was struggling with a severe headache. So I couldn't enjoy the moments there. When I was taking rest, she came and sat beside me and we started talking. I came to know that she was an acupuncture therapist in Toronto. Then we discussed on this headache. I told her every minute details on this. This headache has been started for two years. I am still taking treatment for this but I am not satisfied with the treatment and its effects. While stopping the medicine, the pain again starts with the same intensity. Actually, I am planning to try some other treatments. I think I met her at the right time. She talked about the possibilities of acupuncture treatment on headache. She added that it is safe and non-invasive therapy used for natural healing and reducing pain. Really that was the first time I heard about acupuncture treatment. I would like to know more about this treatment procedure. If anybody has prior experience with this treatment, please share your valuable reviews. Based on your reviews I have to take a decision.
