My stylist always takes the weft and doubles it on it self and braids basically double weft onto my braid? Is this normal? She claims that if she doesn't do this my weave will look to thin and "jacked up". Only reason I ask is because sometimes it makes my hair look almost "too thick" to me. I actually had someone cut and place my clip in weave recently and she didn't do this and my hair looked just as nice. Just wondering if this was general practice or something more rare?
