The number of tape hair extensions that you need depends on the type of look you want to create and your natural hair type. If you are looking to thicken your natural hair, we usually recommend 1–3 packages. If you want to create an extension of your natural hair, between 4 and 6 packages is the most common. However, if you have very thick hair, or want to create a large wave of hair, you may need up to 8–10 packages. Q2:How to remove and reuse tape extensions You can remove your tape hair extensions using a remover and a pin tail comb. The tape dissolves, which allows you to gently remove your hair extensions as easily as you were able to put them in. Next, you remove any tape residue. Then you can reuse the hair by applying new tape refills to the previously used bondings and attach the hair again in the same way. Q3:How to take care of your extensions Before washing you should de-tangle hair from ends to roots.Wash 1-3 times per week for best durability,Wash your hair in lukewarm water and in an upright position. - Apply Hair Oil (avoiding the bond area) to lock in moisture and fight frizz whilst damp. - Nourishes and moisturises hair- Always use heat protec
