I ordered one for my husband. He was having a hard time dealing with the baldness and the affected area was growing gradually. After trying healthy diet plans, biotins, vitamins, and many other treatments, I thought of giving iRestore Laser Hair Growth a chance. I had read the wonderful reviews and as laser treatments are highly effective, I trusted it took work. | When we first tried to turn it on, it did not power up. We had to call the company in order to figure out how to turn it on. The treatment had to be consistent, so my husband did it every day. After a week, he started to feel itchy around the treated area, but we ignored it thinking a good sign. We believed that it was all because of blood circulation. He continued using it. | Then the severe headaches started. He still continued using the system because we did not suspect iRestore to be the cause. We had to consult a doctor and he suggested that we stop using the device for a few days to see if there were any changes. | We did as he suggested and within just a few days the headaches and the itching stopped. It had to be the laser treatment that he had been using for 2 months. We decided that it was not worth it, especially since he had not seen any hair re-growth since he started. | Waste of a product, and from our experience, dangerous.
