Keep beauty products away from direct sunlight. There's someone in another suite in my apartment complex that likes to keep all their beauty things on the window ledge. Yeah it looks nice, but it's not good for your hair, face, and body products.
Avoid leaving them in the car. I don't know how many things my friends have lost to the heat that gathers in the glove box or ash trays of their cars.
Here's a couple tips on how to make your makeup and beauty products last their full lifetime, by avoiding certain climates.
1. Check the label. Does it say to keep you product between a certain temp?
Many hair sprays, and pretty much everything in a pressurized bottle will caution against high temps. This doesn't just apply to direct heat. Keeping these products in a poorly ventilated bathroom, next to the heater, or in direct sunlight can cause the product to change, or the canister to explode.
2. Could it melt?
3. The chemicals may react with direct sunlight, and not be as productive as before.

4. Natural ingredients spoil.
I hope this helps a little bit, and keeps your products lasting as long as they possibly can. Enjoy the summer!!
