Which type of conditioner is most important for providing lasting moisture and detangling effects without weighing down the hair?

The option that provides lasting moisture and detangling effects without weighing down the hair is a leave-in conditioner. Leave-in conditioners are specifically formulated to remain in the hair after washing, allowing them to penetrate deeply and provide continuous hydration throughout the day. Their lightweight formulas help to prevent tangles and provide manageability without the heaviness that can come from other types of conditioners.

In contrast, deep conditioners are typically used for intensive moisture treatment but are rinsed out after a short period, meaning they do not provide ongoing moisture after the wash. Repair conditioners are designed to address specific damage issues in the hair structure, but they may not offer the same level of lightness or detangling benefits as leave-in conditioners. Lightweight conditioners, while helpful in providing moisture, may not be as effective in detangling as leave-in options, which are crafted to remain in the hair and continuously hydrate and smooth the strands.
