I've always hated rooted hair on figures, although the Alien Ripley looks awesome with it. I'm sure it could be fixed with better paint, galactiboy made Drake look great after he repainted it.
I'm not a fan of rooted (Ripley does look good though), I was thinking of the old shave and glue method, like Elvis1976 does on his, or if you are familiar with the military figures side, Tony Barton does amazing work with hair on his figures: https://www.antheads.co.uk/galguide
