Philip B. Oud Royal Forever Shine Shampoo ($75)
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. Make sure you like the rich, woody, masculine scent before purchasing though-it lasts all day.
John Frieda Luxurious Volume ($6)
Some drugstore shampoos smell sweet and fruity-this just smells clean and made our hair delightfully bouncy.
Bumble and bumble Thickening Shampoo ($24)
If it's a slight boost at the roots you're after, look no further than Bumble's entire line of thickening products-a Shampoo ($24), Conditioner ($24), Hairspray ($28), and Mousse ($29).
Kerastase Volumactive Shampoo ($39)
Praise is heaped upon Kerastase's rich conditioners, but don't neglect their shampoos-each one really does what it promises. This makes hair extra soft to the touch, on top of adding volume.
Fat Hair Sulfate-Free Thickening Shampoo ($9)
The name says it all.

Almost all of Pantene's shampoos boost volume, but if you want serious Bardot-like body, reach for this one.

Volume yes, but Oribe's shampoo also increases the amount of texture in your hair-a great option if you like beachy waves.
Fekkai Full Blown Volume Shampoo ($25)

Sachajuan Volume Shampoo ($24)
If you worry about a sensitive scalp on top of limp locks, try Sachajuan. It's seriously effective, but formulated for a sensitive head of hair
