The Outback range of Tea Tree products are free from Parabens and SLS which some people prefer. They also do the amazing Post Wax Spray ... the easiest post wax product to retail to guys!
Their Ingrown Hair Serum is superb too, and it doesn't contain salicylic acid (asprin) that some people can be allergic too.
I do really well retailing them, the lotion, ingrown and spray really do sell themselves.
