Our Brazilian Virgin hair is in a natural color and blonde. The natural hair can be colored as dark as black or lightened as light as 613. This Brazilian straight hair is easy to dye. Clip in hair extensions are usually used to blend with your natural hair volume. If you want none of your natural hair showing to add volume we would suggest you order 2 sets, (according to your hair thickness and length). If you have thinner hair 1 set should be fine. All clip-in hair extensions are of same thickness and contain same quantity of wefts and clips, so longer hair length, the heavier hair weight will be.
