Typically, you can make errors by not reading the instructions and not understanding the steps. You do not want to avoid a 40 minute DVD, and a few hours of studying the method, just to spend the next 6 hours attaching to find you may miss a key step and lose bonds because of it!
Keep in mind most people, at least 95% of them, have great success with this easy-to-use product. Most messages are like this one a recent customer sent in. She says, “I tried the product and I LOVE it !!!“
Look over the instruction manual (hopefully you have one) and then watch the complete DVD while taking notes. Practice attaching in the front where you can see, let the bonds dry 10 minutes and then spray some water on the bonds. Give them a gentle tug to make sure everything is secure. If you lose the bond, practice longer. If it's secure, you are ready to move on! (Only put water on practice bonds to test them. Always wait 48 hours before washing your extensions after applying.)
