My question is to manage hair on move.I am going on a 4 day tour.My hairs are so thick and hard to manage...?

they needed to wash daily using shampoo and then conditioner / hair oil and then only I can set them properly. Also this setting last for only 2-3 hrs then again they become hard shapeless and unmanageable . Also I need to apply lots of oil in night then only hair become good after shampoo. So in tour it is not possible to have shampoo. So is there any instant smoothenar lotion/spray that will keep my hairs manageable for long time ? I dont like products with intense smell. SO suggest a mild/light smelled or smell less product. I prefer natural.
