The method of bonding patented by Great Lengths is of the highest technology. The keratin is a polymer compound whose molecular structure is very similar to that of human hair and respects its same properties and alterations.

Great Lengths Keratin:

When wet, hair expands and when dry it contracts back to
its natural state. Our keratin moves and behaves like your
own hair, ensuring a gentle yet strong hold without damaging
it in the least.

Other polymers:

Unlike our keratin, other polymers do not behave like human
hair. This means that the bond will soon deteriorate and
hair will start to fall out.

Great Lengths Keratin:

Our keratin has been designed so that it is compatible
with elements such as heat, water and sunlight. With correct maintenance, your extensions will remain firmly bonded until you decide to take them out.

Other polymers:

Environmental elements deteriorate the bond and hair starts
to fall out.
