Wool substitute

I want to knit that scarf My so called Scarf for my mom but she is VERY sensitive to wool. Seeing as I am fairly new to this wonderful hobby and I don’t know anything about yarn I was wondering about a substitute yarn that would not make her itch.

Any suggestions?? TIA.

There are soft acrylics out there, and alpaca is supposed to be hypo-allergenic, too. If it’s possible, take her to a yarn shop and let her hold yarns up against her neck. Many wools are non-itchy–the superwash ones and merinos are much smoother and non-prickly than wool.
