Can you post a picture so we can see them? Maybe it's not that bad. If you've rooted the hair and sealed it. I am not sure about putting the head back into the oven. Did you put glazing gel on the lips already? And do you have a genesis heat gun? Lets start there.
The head can go back in the oven with rooted hair, but if it has been sealed, not sure if the glue you have used would be toxic if baked again. Please post pic.I know a mint wash tones down the reds, maybe that might help. If you do use a heat gun don't hold it to close and not very long. Pat B will come and correct our comments if they aren't correct. XXXXX June
Looks like I have given so much advice that everyone's answers are correct without me eh? lol
Yes, what has been said here is correct. You could take a chance and put your bub back in the oven with the hair glued in but like they said, it might not work because of toxins in the glue when baked or going back in the oven can also change the molecular structure of the glue and we don't know what wil happen to it from this point forward.
You could use a heat gun on the lips (like June said... not too close) using some flesh 08 and just a smidge of pthalo green on the end of a tooth pick mixed really well and applied to the lips with a brush. That should neutralize the red for you. Hope this all helps :)
