10 Best Volumizing Shampoos

The OGX Biotin & Collagen Hair Thickening Shampoo is designed to add volume and body to hair, offering up to 72 hours of thicker, fuller-looking hair after just one wash. It’s particularly suited for those with thick hair looking to boost volume and improve hair texture. The shampoo contains biotin (vitamin B7) and collagen, ingredients known to strengthen hair strands and support healthier hair overall. A key advantage is its sulfate-free formula, which tends to be gentler on hair and scalp, reducing the risk of dryness or irritation.

Additionally, OGX uses LipiPro Shield Technology to help protect hair’s natural proteins and lipids, which can prevent damage and maintain hair resilience over time. The shampoo is unscented, which is helpful if you prefer no fragrance or have a sensitive nose. OGX is a well-known brand in hair care with generally positive customer reviews, which adds to its reliability.

The product is mainly targeted at thick hair types, so those with fine or oily hair might not find it as effective for their needs. While it claims to improve hair health quickly, results may vary depending on individual hair condition and usage. The packaging uses recycled plastic and offers good squeezability, providing a nice eco-friendly touch. This shampoo is a solid choice for anyone with thick hair seeking volume and strength without harsh sulfates, though those with other hair types might want to consider options more tailored to their specific needs.

Kérastase Densifique Femme is designed specifically for fine hair, aiming to boost volume, strength, and shine. It uses ingredients like Hyaluronic Acid, Intra-Cylane, and Stemoxydine, which work together to hydrate and reinforce hair fibers from root to tip. This helps hair look thicker and fuller, adding body and bounce without weighing it down. Importantly, it’s sulfate-free, making it gentler on hair and scalp, which is a plus if you want to avoid harsh chemicals. The shampoo is unscented, which could be good if you prefer no fragrance, though some may miss a pleasant smell.

Kérastase is a well-known, trusted brand in hair care, and the product performs well in its intended purpose. Its price might be higher compared to typical drugstore shampoos, and for best results, using the matching conditioner or hair mask is recommended, which adds to the cost. While it’s suitable for all hair colors, it’s primarily aimed at fine hair and may not offer the same volumizing effect on thicker hair types.

This shampoo is a solid choice if you have fine hair and want a gentle yet effective volumizing product backed by a reputable brand, but it might feel like an investment and works best when paired with complementary products.

The OGX Biotin and Collagen Volumising Shampoo is designed especially for people with fine hair looking to add volume and thickness. It contains vitamin B7 (biotin) and collagen, ingredients known to strengthen hair and improve texture, which helps hair look fuller and more resilient. One of its standout features is its sulfate-free formula, making it gentler on hair and scalp, reducing the chance of dryness or irritation compared to shampoos with harsh sulfates. The shampoo promises up to 72 hours of volume, which is quite effective for fine or limp hair.

It also includes a protective technology that helps reduce hair damage and breakage, encouraging healthier strands over time. Users generally like its performance and report noticeable thickening after use. The fragrance is pleasant but may be a consideration for those sensitive to scents. OGX is a well-known brand with a positive reputation, particularly in hair care products focused on repair and hydration.

The shampoo is primarily formulated for fine hair, so it may not deliver the same volumizing effect for thicker or coarser hair types. While it’s sulfate-free, it does not specify being free of other common irritants like parabens or silicones, which might be important for those seeking a fully natural option. The bottle size is generous at 577ml, and it’s made from recycled plastic, which is a nice eco-friendly touch. This shampoo suits adults with fine hair who want a gentle yet effective way to boost volume and strengthen their hair without harsh chemicals.
