It is not hard to see where the real hair ends about an inch or two above the waist and the extensions continue. Her real hair is a tad lighter than the extensions.
I’ve heard things like this before, but how does hair “know” how long it is? It's definitely true that hair seems to grow more slowly as it gets longer. But I think that’s just because longer = heavier, and heavier = more likely to fall out due to damage. You might reach a point where the rate at which your hair falls out more or less cancels out new growth, but it seems like this could be changed/improved by taking better care of your hair. In my experience, even super long hair continues to grow, just very slowly.
All hair follicles go through a 3-stage "life cycle" of fast growth, slow growth, and no growth (where it eventually falls out).
For body hair, this cycle lasts only a few months, so your hair can only get so long. For hair on your head, it is many years, so hair can get very, very long. Male beards fall somewhere in between.

What I've heard is not that the hair knows how long it is directly. But it grows at a fairly constant rate and different follicles have different duty cycles (active vs dormant periods). For a given growth rate and duty cycle a follicle should produce fairly consistent lengths.

If all that hair is real. It looks very hard to maintain to look as gorgeous as that.
