4A Hair Care
4A hair has a well-defined S-shaped coil -- more visible curl pattern than 4B or 4C -- but it still shrinks significantly and dries out fast. The most common complaint isn't dryness alone, it's dryness paired with flatness, because the products that fix one tend to cause the other.

How to Care for 4A Hair Without Losing Volume
Read itWhy 4A goes flat under products that fix its dryness
4A is the most volume-sensitive of the type-4 patterns, precisely because its coil is the most defined and springy of the three. The rich butters and heavy creams that keep tighter, denser 4B and 4C hair hydrated tend to pull 4A's coil down at the root, trading definition for flatness. A lighter, water-based leave-in applied with more focus at the root -- and a heavier cream reserved for the ends -- tends to hold moisture without collapsing the coil.
Still dry, despite being the loosest '4' pattern
It's easy to assume the loosest coil in a tight-textured category would be the easiest to keep moisturized, but the bends in 4A hair still block scalp oil from traveling down the shaft the way it would on straighter hair. That's why 4A routines built entirely around volume -- lightweight everything, minimal product -- often end up dry at the ends even when the roots look great.
