10 Best Volumizing Shampoos 2025 in the United States

The Biolage Volume Boost Shampoo is designed specifically for fine and thin hair, making it a good choice for those looking to add volume without weighing hair down. Its formula includes micro-filtered soy protein and polymers that help provide immediate lift and a fuller look from root to tip. This shampoo is gentle enough to cleanse without stripping natural softness or shine, which is important for fine hair that can easily become dry or limp.

It is also vegan and paraben-free, appealing to those seeking cleaner, more natural beauty products. The brand Biolage, under L'Oreal Professionnel, is well-known and trusted in hair care. The shampoo’s scent, described as Biolage AromaScience™ fragrance, is generally pleasant. While it helps retain moisture, those with very dry or damaged hair might need an additional moisturizing product.

This shampoo is well-suited for anyone with fine hair who wants lightweight volume and a natural shine without harsh chemicals like parabens.

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.

While it doesn’t highlight deep moisturizing properties, it helps maintain light hydration, suitable for fine hair that can get weighed down by heavy conditioners. Moroccanoil is a well-regarded brand in the hair care industry, known for quality ingredients and products that deliver on their promises. The large bottle size is convenient for regular use.

If your hair is very dry or damaged, you might need to pair this shampoo with a more intensive conditioner or treatment, as its primary focus is volume rather than moisture. For anyone with fine, limp hair wanting a boost in volume and shine without harsh chemicals, this shampoo is a solid option.

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.

While it improves volume and strength with regular use, it may not provide intense moisture for very dry hair since its primary focus is density and texture. Also, the floral fragrance might not be preferred by everyone. This shampoo is ideal for those looking to boost hair thickness and manage thinning hair with a reputable product, but users seeking a completely sulfate-free or deeply hydrating formula might want to consider other options.
