Description The Layered HALO® is our most popular extension. Uniquely designed and unlike any other product available, it has 2-3 built-in, gradual layers, providing a seamless blend with natural hair. With 30% more grams than The Original HALO®, The Layered HALO® delivers maximum volume for dense or thick hair. Designed with comfort in mind, our HALO® extensions are non-damaging, virtually undetectable and ideal for adding natural and effortless length and volume without the commitment of other traditional extension methods.
