Heavy conditioners are typically formulated with rich, dense ingredients designed to provide significant moisture and nourishment. When applied to fine hair, these conditioners can create a layering effect that often leads to a lack of volume, making the hair appear flat or oily. For those with fine hair, using products that are too heavy can overwhelm the strands, preventing them from maintaining their natural body and lightness.

In contrast, moisturizing conditioners are generally lighter and focused on hydration without the weight. Protein-based conditioners can strengthen hair but may also lead to stiffness if overused, while clarifying conditioners are designed to remove build-up and should not contribute to flatness. Each type serves a different purpose, making it essential to choose products based on individual hair type and needs.
