Moroccanoil Extra Volume Shampoo is designed specifically for fine or flat hair, making it a good choice if you're looking to add volume without weighing your hair down. It uses a gentle, lightweight formula that cleanses without harsh sulfates, phosphates, or parabens, which is great for maintaining hair health and scalp comfort. The shampoo also aims to boost shine, giving your hair a lively, fresh look. Its signature Fragrance Originale offers a pleasant scent, which many users find enjoyable but could be a drawback if you prefer fragrance-free products.

The Kerastase Densifique Densité Shampoo is designed mainly for fine and thinning hair, aiming to add volume and strengthen hair fibers. It includes hyaluronic acid, known for its moisturizing and hair-thickening properties, which helps restore bounce and fullness. Suitable for all hair types, it offers a floral scent that is generally pleasant but may not suit those sensitive to fragrance. This shampoo is not explicitly labeled sulfate-free, which means it might not be the gentlest choice for extremely dry or color-treated hair. However, it excels at deep cleansing, removing buildup effectively to leave hair feeling lighter and fuller. The brand Kérastase is well-regarded in professional haircare, known for quality and targeted formulas. Additionally, the shampoo comes in an eco-friendly refill pouch made from recycled plastic, which appeals to environmentally conscious users.
