Envy’s hair add-ons are perfect for individuals wanting more body and coverage for fine or thinning hair, or for those who just want to add a little extra oomph to their do. Available in our 10 most popular colors, the lightest tones are made from human hair with synthetic strands blended in to achieve the most natural-looking colorations. They can be trimmed to blend seamlessly into your preferred hairstyle, adding body, length, and fullness for a more voluminous look.
