Can Anyone Help Explain These to Me

Remember if you buy single drawn remi hair it is cut at the top
only and the tail is left uncut and natural. Single drawn is made
up of short and long natural hairs. This is why it is uneven with
all different lengths at the bottom and sometimes split. Double
drawn Remi is cut straight at both ends. This hair is almost
double in price and better quality with less chance of split hair
on the ends. It can take up to 12 bundles of single drawn remi
to make 1 bundle of double drawn remi. If you can't afford
double drawn remi then I suggest getting single drawn and
ordering that extra few inches and cutting off split hair. If you
see someone selling double drawn remi hair for the same
prices or close to single drawn remi then question it. The
chances are it may not be the real deal!! Your may be getting
single drawn which someone has cut off the ends to make it
look double drawn or you may be buying non-remi hair, which
is hair root & ends mixed in different directions (not good
quality). Double drawn should be the exact thickness at the
head and tail and all the hair should be exactly the same length
from top to bottom. Just a few words of advice to look out for.
Somone who does not have a great knowledge of hair may be
fooled and think it really is double drawn remi. It is much more
expensive.

i did a search real quick and this was SAS's reply..it was under the bliss hair topic

I tryed to find that same thred too and no luck. Remi I belive  is a term many companys use to describe human hair. single draw is the pony cut off the head . It is only cut that one time so if you ordered 18 inch the botom will be very thin. double drawn has been cut at the botom too so 18 inch double drawn will be better and thicker at botom and more expensive. I hope I am remembering this right some of the sites selling virgin hair explain this too.Non remi I'm not sure maybe synth or hair colected from brushes not cut from a person.
