Do you have unfinished bottles/tubes of shampoos or conditioners sitting in your bathroom shelf? Soaps that are melting but unused for weeks? Do you have bottles and bottles of lotion you bought but don't use? What a waste of money, right? So how about using those without the guilt feeling of "bought but never used, what a waste!"
Make a list of your unused items and see if you can use it for other purposes. Example of re-purposed products I made below:
Shampoo-- use as make-up brush cleaner
Conditioner--use it as a treatment. I put it on for 5-10min with shower cap while I am doing other things (cleaning my room, doing the laundry--talk about multi-tasking!) then after doing the dirty chores, I take a bath. The hair felt softer after the bath. Probably the hair's natural oil came out.Good, right?
Soaps--use it to wash your delicate laundry i.e. lacey bra/panty :-)
Lotion--don't like it already? use it as a foot lotion. or share it with the family. put a bottle/tube in the kitchen or one in the garden for those times you need a moisturized hand asap!
Colognes--use it as room spray or linen spray. Nice!
