Great Lengths’ keratin is often imitated, but what makes it so unique is its ability to mimic the structure of human hair on a molecular level. This keratin is hypoallergenic and will respond to heat and moisture the same way our natural hair will. When it gets wet or heated, it will expand and contract with our natural hair.
With this method, small sections of your natural hair are selected, and pre-bonded extensions of equal density are applied (strand by strand). They are then rolled around the natural hair just below the root, making them comfortable and safe, with full range of motion. This means when applied correctly, ponytails are totally doable!
Great Lengths is a patented method of keratin-bonded hair extensions. The thermal application method continues to be one of the safest and most sought-after extension techniques available to this day.
