I have a fondness for people's natural body scents, and it saddens me when they cover that up with fake/chemically soap, deodorant, and other heavily scented fragrances.
I think an unscented soap, or something natural and infused with essential oils, is the way to go. So many beauty and hygiene products these days are full of crap ingredients, so I appreciate going back to the basics.
I make my own soap and deodorant for personal use, out of all natural/raw/virgin/organic ingredients. I love knowing what I'm putting in and on my body! For my body wash, I use coconut oil, sea salt, essential oils (whatever I feel like at the time; I gravitate towards "woodsy" scents), and just a dab of fresh lemon. For my deodorant, it's much the same, except I add in some rubbing alcohol, apple cider vinegar, and then way more essential oils to cover up the harsh smell of those two ingredients.
For clients, I always bring my own supplies to my incalls. I have an unscented soap for the shower (Dr. Bronner's), a lightly scented natural soap (one for shower and one for sink), and two shampoo options. I bring a giant jug of natural mouthwash, with tiny little one-time-use cups. I bring natural essential oil body wipes, and floss (the little pick variety, not the long bit of string), and Listerine. There is no excuse for my clients to not have immaculate hygiene! With clients, my big thing is options. They are paying a lot of money for an experience with me, so the least I could do is provide them with a few options so that they can choose the hygiene products that best work for them.
