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.

Bumble and bumble Thickening Volumizing Shampoo is designed especially for people with fine to medium hair looking for an easy way to add fullness without weighing hair down. It’s lightweight and works best when paired with its matching volumizing conditioner to help hair appear thicker and more voluminous. The shampoo includes Panthenol (Vitamin B5), which helps keep hair moisturized and healthy-looking, addressing dryness often caused by volumizing products. It's also color safe, so it won’t strip or fade dyed hair. The fragrance combines fresh scents like bergamot, cedarwood, and crisp apple, offering a pleasant but not overpowering smell.

This shampoo is made for straight to wavy hair, so those with curly or very coarse hair might not see the best results. Bumble and bumble is a well-known brand trusted for quality haircare, which adds confidence in its effectiveness. If your main goal is to add instant volume while keeping hair moisturized and maintaining color, this shampoo is a solid choice, especially for those with finer hair types, though it may not suit all hair textures or those specifically needing a sulfate-free 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.
