European hair is considered the best hair in the world. It is the natural cut color from the head, making color choices narrower but coloring capability better. European hair is soft and silky. It lays flat and moves. However, because it is the best does not necessarily mean it is the best for you.
The best hair in the world is the best hair that works for you! Most people with hair loss want to look like themselves. Texture matters when matching and blending. I personally do not wear European hair because my hair has a curl, kink, and frizz in it, so to wear fine hair was too different and did not look like me.   You need multiple choices and options. You need to be able to see what the differences are. That is where a hair loss specialist comes in. They will have multiple options and price points.
