Great Lengths' patented bonding method is cutting edge technology, using a keratin polymer compound whose molecular structure is very similar to that of hair.
When wet, hair expands and when dry, it contracts back to its natural state. Great Lengths' keratin moves and behaves like your own hair, ensuring a gentle yet strong hold without damaging it in the least.
No other system treats your hair in such a gentle way, putting an end to gluing, knotting and welding. It's a revolutionary system; an extremely durable, yet gentle, bonding invisibly attaches Great Lengths hair to your own.
