Luckily, I know how to use a hair conditioner that doesn't work on my hair.
I use it as a shaving cream. Yup, I wet my legs and apply the conditioner all over my legs. Then I shave. Makes my legs smooth and soft.
I wouldn't recommend it to use it every day, still is a hair conditioner, but for occasional shaving or when you're travelling should work well.
Do you have any other recommendations how to use a hair conditioner which doesn't work well for your hair?
Until next time, be happy and keep your legs smooth ;)
