The stuff I use is kinda expensive, its 8 dollars a bottle and although it may not sound like a lot to some of you to me it is. That's my one splurge and I can't afford to keep buying it so often because she wastes it.
I've tried explaining she only needs a quarter size amount. I've also bought her several different brands of shampoo and conditioner for her to use from cheap stuff to some that costs 4 bucks a bottle but for some reason she wants to use mine. I've also tried hiding my stuff, first in the bathroom and she would find it and use it and then in the bedroom but she complained to my husband and he says its childish to hide the shampoo from her. And while I admit it is, it's the fact that its expensive and I can't afford to buy two new bottles every time she comes over.
Any other ideas? I wouldn't mind if she didn't waste it but i can make a bottle of shampoo last 6-8 weeks and a bottle of conditioner last 4-6 weeks and when she uses it I have to buy 2-3 bottles of each every month. Its ridiculous and wasteful.
