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 Redken Volume Injection Shampoo is designed specifically for fine hair that needs extra lift and body. It uses a volume-boosting ingredient called filloxane, which helps add fullness right from the root without weighing hair down. This shampoo is paraben-free and has a gentle formula that also cares for the scalp, making it suitable for daily use. It leaves hair feeling soft, shiny, and more manageable, which is great if your hair tends to look flat or lifeless. The scent is a light aloe vera fragrance, which many find fresh and pleasant without being overpowering.

While it does not explicitly state it is sulfate-free, it emphasizes gentle cleansing, so it should be less harsh than many regular shampoos. The addition of softening silicone polymers helps smooth hair, but if you prefer completely silicone-free products, this might be a downside. Redken is a well-known professional haircare brand, giving this shampoo a solid reputation for quality.

Those with very dry hair might need extra moisturizing products alongside this, as its main focus is volume rather than deep hydration. This shampoo serves as a strong choice for anyone with fine or flat hair looking to boost volume and body with a gentle yet effective formula.
