@Frenchy-C it could also be that your daughter's skin is like mine - does not like olive oil when the soap is new. I noticed that even around 4-5 months cure, if my soap has more than 15-25% olive oil, it's drying for me.
I've taken it out from almost all my recipes and replaced with RBO. My son uses a 70% RBO soap and while it does need more cure time than normal as well, it's still better than olive oil for us.

I will agree though, that handmade soap isn't for everyone. Sometimes, you'll really have to use a syndet of some sort, liquid or solid.
