If you want your hair to grow just use 2% minoxidil once a day and order a red light therapy cap from eBay and put it on for 20 min a day . You will see great results with both after 3 months. Keep using them. Your hair will shed less, grow thicker and faster. Just use rogaine once a day, no need for twice a day. One application works for 22 hours so you are wasting the product putting it on twice a day. It won’t make it work any better doing it twice a day.
