By waxy deposition on the leaf surface and closing of stomata
Yes a leaf can not have a waxy surface if it is so adapted. The waxy surface is designed to keep water off, and inside of the leaf. Leaves in the rain forest often have a waxy surface to keep from being constantly saturated in water.
The answer you are looking for is Cuticle (a waxy lipid covering plants)
Desert plants have well developed vascular tissue and root system, have latex in the body, spiny, waxy and cuticularized surface to minimize water loss by transpiration.
The waxy coat helps to reduce water loss from the leaves.
Not all leaves have a waxy surface, but some do. Plant cuticles are a protective waxy covering produced only by the epidermal cells of leaves, young shoots and all other aerial plant organs without periderm.
By waxy deposition on the leaf surface and closing of stomata
Waxy layer on outer surface of green plants is called cuticle .This cuticle is actually present in outer cell walls of epidermal cells . The wax present in cuticle is a type of lipid . It is waterproof layer which prevents excessive loss of water by transpiration . It also protects plant from abrasive damage. Wax is chemically a mixture of esters of long chain fatty acids eg cerotic acid , montanic acid , long chain alkanes , alcohols , ketones .

the waxy material in the leaf is called "CUTIN"
Being able to store water, and to have a waxy surface to reduce water loss, are the two main adaptations.
Desert plants have well developed vascular tissue and root system, have latex in the body, spiny, waxy and cuticularized surface to minimize water loss by transpiration.
they have a waxy coat
A few desert plants have a waxy coating that helps protect them from the heat and dry air of the dessert. These plants include some varieties of Yucca trees, Creosote and Beavertail Cactus. The waxy coating blocks the plants pores, trapping the moisture inside to prevent them from drying out.
The waxy coat helps to reduce water loss from the leaves.
The waxy waterproof layer that cover most plant leaves and stems is called a cuticle. The cuticle is thicker on the upper half of a leaf's surface, and it is waterproof so as the internal areas of the leaf are kept secure from flooding, That's why you water plants at the roots.
