Phospholipids are made up of both water loving, and water repelling materials.
They head, which is made of glycerol, is water repelling and therefore forms the outer and inner parts of the cell, away from the water. Where as the tails are made up of fatty acids that are water loving and point in between the heads, and into the water between the two glycerol layers.

Phospholipids are the molecules that have heads and tails in the plasma membrane. The phospholipid bilayer is made up of two layers of phospholipid molecules, with the hydrophilic heads facing outward towards the aqueous environment and the hydrophobic tails facing inward, creating a barrier that separates the inside and outside of the cell.
A phospholipid is a type of fat found in the body. Phospholipids are made up of a polar hydrophilic head and a nonpolar hydrophobic tail. Hydrophilic means water-loving and hydrophobic means water hating.
Phospholipids are made up of a hydrophilic head and a hydrophobic tail. The head group has a 'special' region that changes between various phospholipids. This head group will differ between cell membranes [types of cells] or different concentrations of specific 'head groups'. The fatty acid tails call also differ, but there is always one saturated and one unsaturated 'leg' of the tail.

The head of a phospholipid is a phosphate group and is hydrophilic, which means it is attracted to water, in particular the intracellular and extracellular fluids.
The head (or top) of a phospholipid is polar and the carbon chain tail is non-polar.

Beside alcohol, the head group of a phospholipid can be made up of a charged or polar group, such as choline, serine, or ethanolamine. These groups help determine the overall properties of the phospholipid and its interactions with other molecules in cell membranes.
The water-soluble portion of a phospholipid is the polar head, which consists of a glycerol molecule linked to a phosphate group. This region is hydrophilic and interacts with water molecules. The hydrophobic tails, usually made of fatty acid chains, form the nonpolar, water-insoluble portion of the phospholipid.
The phospholipid bilayer in cell membranes is both polar and nonpolar. The heads, which face the outside and inside of the cell, are polar. Thus they form hydrogen bonds with the water outside of the cell and the cytoplasm inside the cell. They are called "hydrophilic," which means they love water. The tails are on the inside of the bilayer and are nonpolar. They are hydrophobic, which literally means they are scared of water.
