Garnier Fructis Grow Strong Thickening Shampoo for Fine Hair, 33.8 fl oz — Biotin & Vitamin C

Garnier Fructis Grow Strong Thickening Shampoo is a biotin- and Vitamin C–infused cleansing formula designed to add visible fullness and body to fine hair without weighing it down.

This large 33.8 fl oz bottle of Garnier Fructis Grow Strong Thickening Shampoo is part of a three-step Grow Strong system that includes conditioner and a 10-in-1 leave-in treatment. The formula combines biotin, Vitamin C and blood orange extract to boost hair texture and appearance, while avoiding parabens, silicones, phthalates and DMDM hydantoin. Packaged with sustainability in mind, Garnier’s bottles (excluding caps and pumps) are made from recycled plastic, and the brand is Leaping Bunny certified for cruelty-free practices.

How does this shampoo make fine hair look thicker?

The shampoo gently cleanses while ingredients like biotin and Vitamin C help improve the look of body and fullness on each strand. Instead of coating hair with heavy silicones, the formula aims to lift hair at the roots and enhance overall texture for a fuller appearance.

• Biotin supports the look of thicker, stronger strands
• Vitamin C adds brightness and helps texture appear more volumized
• Blood orange extract delivers a fresh scent and lightweight conditioning
• Free from parabens and silicones to avoid buildup

Will it weigh my hair down or change styling?

Garnier Fructis Grow Strong Thickening Shampoo is formulated to avoid heavy residues so styling stays predictable. Users typically find their hair feels lighter and more manageable, which helps lift and hold styles better.

• Lightweight cleansing won’t flatten roots
• Designed to pair with matching conditioner and leave-in for best results
• Compatible with heat styling and everyday routines

What ingredients should I expect and what’s omitted?

The key actives—biotin, Vitamin C and blood orange extract—aim to enhance fullness and surface texture, while the formulation deliberately excludes certain additives. Garnier also emphasizes sustainable sourcing and cruelty-free certification for this line.

• Includes biotin, Vitamin C and blood orange extract
• No parabens, silicones, phthalates, or DMDM hydantoin
• Leaping Bunny certified and vegan-friendly
• Bottle (excluding pump/cap) made from recycled plastic

How should I use this shampoo for best results?

For fuller-looking hair, use as the first step in the Grow Strong system—cleanse with the shampoo, follow with the Grow Strong conditioner, and finish with the 10-in-1 leave-in treatment. Regular use as part of the three-step routine is recommended to maximize visible fullness for up to 72 hours as indicated by the system.

• Apply to wet hair, lather, and rinse thoroughly
• Follow with Grow Strong conditioner for added body
• Use the leave-in treatment for styling and extended fullness
