Great Lengths pigmentation
The new color pigments occupy the space freed by the depigmentation process. A method for ensuring the color does not change.
In traditional dying the color molecules typically do not have enough space and cluster in areas already occupied by fragmented, bleached molecules. The color will release after several washes.
This will not happen with the special Great Lengths process. Great Lengths has the best coloring processes.
After drying, hair is combined into natural shades so the transition between the extensions and the natural hair cannot be seen.
