Hair Extension

Application & Recommendation

For a full hair extension, we recommend the following quantities depending on your hair structure:

• 2 packs for normal natural hair

• 3 packs for particularly thick natural hair

This is how you achieve a harmonious, voluminous result with optimal hold.

Our GSG Seamless Lux Strands Extensions are the ideal complement to the Seamless Double Weft Extensions. They are particularly well-suited for application in highly visible contour areas – for an invisible transition and an especially natural result. The Lux Strands have been specially developed for sensitive areas like the temples or hairline and blend seamlessly into your own hair.

Combine both systems for a perfectly coordinated, seamless hair extension from root to tip.

Hair Thickening

Application & Recommendation

For natural hair thickening, 1 pack of our GSG Seamless Double Weft Extensions is usually sufficient. The required amount may vary depending on the desired hair volume and individual hair structure.

Our GSG Seamless Lux Strands Extensions are perfectly suited as a targeted supplement in highly visible contour areas. Thanks to their particularly fine construction, they can be applied where maximum invisibility is required – for an absolutely seamless transition to your own hair.

Combine our two extension systems for a customized result that guarantees both volume and naturalness – ideal for anyone who wants gentle, discreet thickening.
