Easy to dye, and water color this Swedish blonde body straight hair. 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. Depending on care, the life of the hair should last 1-2 yrs.
