I just made 2 - yes 2 - batches of soap (one for shampoo for me and one for my sister) with rosemary. My house REAKS! It just plain stinks to me, if I didn't love my sister as much as I do and if I didn't pamper and baby my hair to the point of being willing to suffer (phenomenal for the hair mixed with joboba and oo) I'd never use the stuff!
However, I do know that a great number of people love it so if you're thinking of adding to your line, it would probably be the icky rosemary.
Mint, on the other hand... now we're talkin! Mmmmm, getting into the shower 1/2 asleep and knowing you have a very long hard day ahead and smelling that mint... yeah, THATS the way to start the day (of course with a good cup of coffee while you're in the shower waiting for the fog to clear..
