The dark shades of the Vietnamese range are Virgin. Meaning it has had no chemical intervention in its lifetime and therefore, will last an exceptionally long time (in addition of 3 years in many cases). The lighter shades have been lifted as gently as is possible, leaving very little damage resulting in a sustained long life (in addition of 2 years in many cases).
Vietnam is known for its high Omega 3 diet; fish oils, nuts, seeds and green vegetables. This diet allows for exceptionally strong hair with a deep and long lasting shine. The hair is soft to touch and fingers flow through with ease. Due to its strength, it is more coarse than the other 2 ranges.
This range is naturally double drawn, meaning the thickness flows through to the very ends, however it does contain a small amount of short hairs. This is because the high quality hair is exceptionally rare.
The Russian range is the softest to touch out of the 3 hair types. Fingers flow through with ease and it holds its lustre for its life span of 9+ months. It is absolutely double drawn (approx 95% long hairs).
This is the budget range. Hair is soft, fingers flow through with ease but it does snap more rapidly and most of the lengths are single drawn; meaning it thins towards the ends.
