Which thickness is best for me?
[+] View Thickness Guide

All our clip-in & invisible wire extensions are available in full head sets that are made of high-quality hair. The higher the grams, the more hair is attached to each weft. The reason we provide these weight options, is to help you find a set that is suited to your own haircut and hair thickness.

If you have thin/fine, medium to long hair and you want to add volume and length, without overwhelming your look, we recommend 'Standard' hair extensions.

If you have average thickness, medium to long hair and want to add volume and length, our 'Thick' set is your ideal match because it created the perfect balance of length and volume.

If you have short, layered or thick hair and would like to add length to your hair, go for the 'Very Thick' set. This set will give you the most natural look since it matches your own hair thickness and will blend seamlessly with shorter hair cuts.
