I learn you nothing by telling that the frizzy hair shrink a LOT until 75 % of their size when they are wet. It is what we call the shrinkage. Fortunately, there is a method of banding which is so effective to maintain hair stretched and disentangled. Discover more in my article.
The shrinkage define the natural capacity for frizzy to become shorter once they are wet. Hair length can be reduced about 75 % of the total length of a hair.
This is so frustrating to have this effect in particular when like me you want to grow your hair as much as possible!!! However shrinkage doesn't affect the natural growth of hair as they grow normally 1 centimeter a month.
