No! Never ever have I seen that... or heard of it... I would have to stop them! A lot of women wear a wig with a totally different colour to their own hair - so they definitely wouldn't want to be pulling out any baby hair. Who wants to pull our their own hair and then stick something highly sticky down on top of it? That is going to pull those hairs out like waxing... the only time I ever use my own hair with a wig is if I am non-bonding and wearing a lace front and I might choose to blend with my own hair. The thing is, I would get a weird apperance under the lace where those baby hairs were stuck down under it as to be poking out, they must be under/behind where the front of the wig it is sitting and thus squashing the baby hair before it pokes out surely?! The reason the wig has baby hair, is because the wig maker assumes you won't... because yours will be underneath the wig!
