Im a Newbie...

hey everyone! i have been searching through some forums now for the past few days and i am thinking about getting my first full lace wig. I got the definition down for Yaki and light yaki but what is Yacki Straight? Is it the same thing as Light yaki? I saw this lady on youtube and her unit was beautiful... on her website she says it is Yack straight but if i can figure out if she means Yaki or Light Yaki. Im sure i can get a better price straight from a CV though. Ive been hearing so much about Rex and Jacksun. Can someone take a look at her video and if you know what type of hair it is let me know. Her unit is the exact type that I am looking for. Help me please!
