Overhydrated (or over-moisturized) hair looks limp, mushy, and lacks bounce, with curls that fall flat and lose definition, feeling heavy and stringy, even developing soft frizz and stretching without snapping back.

Letting hair dry naturally isn't inherently bad, but it's not always the best either; wet hair swells and becomes fragile, increasing risk of damage over time, especially for thick hair or if you sleep on it, while heat drying can cause surface damage, so a balance is key, like gently blotting with a microfiber towel and air-drying partially, or using a diffuser. The main issue is prolonged wetness, which weakens hair, so gentle techniques are crucial, whether you air-dry or use heat.
