I've only discovered the joys of homemade soaps fairly recently, found a seller at our local downtown market and decided to try it out, and it rapidly spiraled into a sickness, lol. I ordered more online, bought several bars from the local lady, and then decided to take the plunge and try making my own.
It is research in a way, I guess. I've been reading the labels on the ones I adore as well as the ones I'm not so crazy about, trying to get an idea of which oils and additives are contributing to the way they feel. Can't say that I'm soap-savvy enough to really get that right yet, but I'm hoping that making a bunch more of my own batches will help with the comparisons.
