questionswhat is the best way to dispose old shampoo…


Unless the shampoo's something unusual, and toxic, I'd use it for making a nice wash for tossing on plants with aphids and similar pests. I wouldn't worry too much about pouring them down the drain (unless you have a septic tank, which is unusual in outside of rural/semi-rural areas). After all, when you use them, the residue is going down the drain. I don't know any other uses for conditioners, but the shampoo's a serious suggestion.


I agree with @shrdlu. Bugs hate it when you put soap on your lawn and the grass doesn't care so it will still grow. We have a chinch bug problem over here and soap is the most natural solution to get rid of them. Otherwise, we have to put down toxic chemicals.


Actually shampoo (& probably gels) are excellent to hand wash delicates. This is a travel tip I've used & really works. Pour them all into 1 bottle to conserve space. Unsure about conditioners, just check the ingredients - you might be able to use them in the same way.


If you should have any unopened ones, donate them to your local women's shelter. They are always in need of "vanity" products to help the ladies feel better about themselves and to get them ready for interviews.


Shampoo can also be used as hand soap (if you have dry skin, it's best to use these only in the summer, as they can dry your skin). Conditioner is great in place of shaving cream/lotion for shaving your legs.
You could pour some into smaller bottles to use when traveling, at the gym or otherwise not showering at home.


Along Moondrakes comment, many cities also have a women's intake shelter for abuse/rape. My wife and I always collect the extra shampoo/conditioner/lotions when we travel for work to donate to those centers.


Although the charity thing is nice, I prefer making a home-made slip and slide. Buy a big tarp, squirt shampoo/conditioner all over, spray with the hose, run, jump, slide.


@bund9032: Good point. The travel sized bottles from hotels are welcome at almost any non-profit, from homeless shelters (for obvious reasons) to senior centers, where they are strangely popular gifts for the attendees. Everyone here at the office collects these when they travel and all our diverse grantee agencies are glad to have them.


We use ours until it's no longer feasible to do so, rinse the bottles in the sink and recycle them.


Diluted shampoo works great to clean the sink and tub, using a nylon scrubby and a little elbow grease. Can also be used to swish out the toilet.
