unfortunately not 8( if you were working with another program other than mspaint, i would suggest selecting the space around the hair and expanding that selection, then filling in that space to sort of help you find the general outline and work with that from there, but because mspaint was designed to be very simplistic there aren’t many features to work with 8(
though you did say pixel by pixel, that’s kind of tedious so you could just make the brush bigger to quicken the pace you’re working at? ; v ; sorry we couldn’t be of much more help
i believe you can do the process i just described on gimp though, which is a free program if you’re interested in downloading it
