Read on for the best thickening shampoos on the market, now.
Best Overall: Philip B. Forever Shine Shampoo
The price tag might be shocking, but this formula really does transform your hair, thanks to time-released hydrators and a slew of amino acids, peptides, and botanical oils. It's also safe to use on color-treated hair. But make sure you like the rich, woodsy, masculine scent before purchasing—it lasts all day.
Best Budget: Pantene Hair Volume Multiplier With Bamboo Shampoo
Almost all of Pantene’s shampoos boost volume, but if you want serious, Bardot-like body, reach for this one. It's geared toward those with fine hair, removing the dirt and oil that so often weigh hair down and imparting plenty of fluffy fullness.
Best Drugstore: John Frieda Luxurious Volume Thickening Shampoo
Some drugstore shampoos smell sweet and fruity—this option by John Frieda just smells clean and made our hair delightfully bouncy. It's formulated to restore hair from the inside out‚ restoring fullness and texture from the root.
Best Softening: Kérastase Paris Bain Volumifique
Praise is heaped upon Kérastase’s rich conditioners, but don’t neglect their shampoos—each one really does what it promises. This particular product makes hair extra soft to the touch, on top of adding volume.
Best with Biotin: R+Co Dallas Thickening Shampoo
Biotin and vitamin B5 act as the key ingredients here, penetrating the hair shaft and strengthening from within. Coconut oil adds shine while saw palmetto berry extract imparts volume.
Best Sulfate-Free: L'Oreal Paris EverStrong Thickening Shampoo
You don’t need sulfates to score volume. If you have color-treated hair—or have read enough about sulfates to pay attention to the ingredients on the label—try this formula.
Best Texturizing: Oribe Shampoo for Magnificent Volume
Polymers in this cult-favorite Oribe shampoo coat the hair, adding volume and thickness (botanical extracts leave hair shiny and lush). In addition to volume, Oribe’s shampoo also increases the amount of texture in your hair—a great option if you like beachy waves.
Best Lightweight: The One by Frederic Fekkai The Uplifting One Volume Shampoo
Some thickening shampoos can weigh the hair down, leaving a dulling residue on blonde locks. If you’ve experienced that problem, try this one—it’s surprisingly light. It's also formulated without parabens or sulfates, and it contains a UV filter, to protect hair while out in the sun.
Best for Sensitive Scalps: Sachajuan Ocean Mist Volume Shampoo
If you worry about a sensitive scalp on top of limp locks, try Sachajuan's Volume Shampoo. It’s seriously effective, but formulated for a sensitive head of hair. Even better: a combination of marine algae extracts imparts shine and strength to even the limpest of locks.
Best Strengthening: Kiehl's Rice and Wheat Volumizing Shampoo
Kiehl’s formula doesn’t just make your hair look thicker, it also reinforces each strand from the root with antioxidants and fatty acids. Honey works to moisturize and soften, while hydrolyzed wheat and rice proteins strengthen and nourish the hair.
Big Sexy Hair Color Safe Volumizing Shampoo and Conditioner
It might have a slightly sweet scent, but Big Sexy Hair’s shampoo adds fullness while smoothing—everything you want in a shampoo when you have fine hair.
