Yes, some folks do use shampoo to wash their woolens and hair conditioner as softener...
Well, they're hairs, just ones of a sheep....
I used to use shampoo a few times, as kid, for washing my mom's rabbit collar sweaters and wool in absence of specific detergent, but I preferentially sticked to wool detergents as I loved their scent more, but using hair conditioner on rabbit collars that was magic as it gave them extra shining and volume, just as advertised and were meant to do on hairs...
But fabric softener worked just fine also, and they works better on natural and synthetic fibers, also for wool...where they're meant to work.
I think that:
More TOL/ high end conditioners are best used in "live" hairs with live follicles and roots, as they leave many nutrient oils, aminoacid, vitamins and stuff for hairs that are absorbed from our follicles... I think that perhaps .in "dead" hairs or woolens, using such stuff may result in filling them with ingredients oils etc they will never have chance to absorbe....
But BOL/low end , cheap, hair conditoners, do not usually have such ingredients, and just are plain basic softening agents not doing more than that, and more than what fabric softener does, they perhaps may have added some shining and reflex enhancer that wil work on lucid animal fibers and so on furs or fine wool, but no more than that...
