Does deep wave hair with closure flatten over time?

Yes, deep wave hair with closure can appear to flatten over time, especially if it’s not cared for in a way that preserves its natural wave pattern. Deep wave textures are created through a defined wave set, but daily wear, friction, product buildup, and moisture loss can all loosen those curls slightly, making them look less bouncy and more relaxed. This doesn’t mean the hair is damaged — it’s just responding to gravity, styling, and environmental exposure.

To keep the waves intact, regular maintenance helps a lot. Moisturizing with a lightweight leave in conditioner keeps strands supple and prevents frizz that weighs waves down. Gently scrunching the curls when damp, rather than brushing, encourages them to spring back into shape. Avoid heavy oils or dense products near the roots, as they can weigh the pattern down and create a flatter look.

With closure pieces, the top section especially can get flattened if it’s constantly styled in the same direction or tied up tightly. Rotating your parting or using soft styling techniques that lift at the roots helps maintain dimension.

So while deep wave hair with closure might soften a bit with time, mindful care and styling techniques help preserve its natural movement and wave definition for longer.
