Phosphate molecules.
The head (or top) of a phospholipid is polar and the carbon chain tail is non-polar.

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.
Phospholipid molecule is actually almost similar to a lipid molecule. It is a alcohol connected to 2 fatty acids and a phosphate group.(In lipids, its connected to 3 fatty acids)
Because the permeation through a membrane depends on the diffusivity (size of the permeate molecules) and the solubility (briefly the interaction equilibrium) of the permeate in the membrane. Considering permeate mixtures, membranes can be size-selective and sorption-selective depending on which relative term (ratio of diffusivities or ratio of solubilities) dominates. Most known membrane separation processes involve size-selectivity, i.e., the "smaller" the permeate molecule, the faster it gets through the membrane. More sophisticated membrane separation processes are sorption selective, where it is possible that the "bigger" molecules exhibit a higher permeation flux than the "smaller" ones.

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.
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.

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.
No, you do not have that quite correct. A Phospholipid molecule has one end that is hydrophilic (is attracted to water) while the other end is hydrophobic (is repelled water but is attracted to fats).
