To make sure that the extension can grab your hair appropriately and rest secure on your head on both ends, you have to attach a hair clip at either end of the weft. Step 4: Repeat steps 3 on the other pieces of hair. Pull tight to secure the attachment and repeat this 3 to 4 times for a very secure track. Pull the needle through the hole, starting at one end and following with the thread until you reach the end. Hair clip has holes along the top and bottom of it. Place one clip at either end of the weft. Make sure your hairpin’s teeth are facing up. Step 2: Fold the hair’s weft over in half, and align the ends. Therefore, you must consider back and sides of your hair, if you want to do the crown. As we know, most sections need at least two tracks. You can use a standard row of extensions and fold it to add a volume getting more volume per track. Most hair tracks are between 4 and 8 inches in length. Step 1: Decide how many tracks to create. However, we can make hair tracks from extensions by ourselves for free to change length and volume. Although hair extensions can help to change hair length and volume, it requires high fees to maintain.
