While going on vacation this year, instead of putting shampoo, conditioner, etc. in zip bags to prevent products from leaking in suitcase, just take the lid off and put a piece of Handi Wrap or Saran Wrap over the bottle opening.
When going camping or on a trip, pack toothpaste, shampoo, cologne and anything else that might leak in a ziplock baggie. This way, if there is a spill, your entire luggage won't be messed up. By Sandi
To keep your bottles of makeup, lotions, and shampoo from leaking all over your clothes and suitcase, place some cotton in the cap before closing. This will keep it from leaking out!
