How to Get Volume in Your Hair

The Best Shampoo for Women's Hair Loss

Hair questions,
meet answers

What is a volumizing shampoo?

Volumizing shampoos help to make your hair look fuller and denser. Once massaged in the scalp, the shampoo targets your follicles and the bottom of the hair shafts to lift hair away from the head. Depending on the ingredients, volumizing shampoos will usually lift your hair without leaving buildup or weighing hair down, thus creating more body.

How does volumizing shampoo work?

Most volumizing shampoos contain ingredients that create 'hold' to lift hair away from the head. Our sulfate-free volumizing shampoo contains Biovolume 128™, which is designed to provide maximum volume and help support fuller-looking hair. In one survey of Biovolume 128™, 90% of users saw an increase in hair volume after 28 days*.

Biovolume 128™ is rich in phytochemicals such as polysaccharides, flavonoids, peptides and amino acids. Naturally found in linden buds, these ingredients form a protective barrier over the hair cuticle to protect it from external damaging agents like UV light and chemical processes, while making hair shiny and smooth.

Note that volumizing shampoos are different from thickening hair shampoos. Thickening shampoo thickens each strand of your hair by infusing it with protein or collagen. Unlike a volumizing shampoo for fine hair, thickening shampoo usually includes ingredients to address hair loss, like saw palmetto. If you’re looking to support hair growth, check out our thickening shampoo.

*Based on a survey of 40 participants after 3 uses per week during a 28-day period.

Will volumizing shampoo work on fine hair?

Hair volumizing shampoo is designed to work well on different hair types, including fine hair, color-treated hair and thin hair. Most women who use volumizing shampoo like that the formula is lightweight and doesn’t weigh hair down (plus it's a 100% sulfate-free shampoo)—making it especially perfect for those with flat, limp, oily hair or fine hair.

How else can I add volume to hair?

A good volumizing shampoo, like Hers Full Volume, is just the very first step of your hair care routine. We also recommend using our volumizing conditioner, which helps moisturize, plump and prep hair for easy styling.

You can do a lot to make your hair appear fuller with your hairstyle. If you have fine or flat hair, styling your hair with too much product can result in greasy, limp hair. On the flip side, a blunt cut or roller set can help disguise your thinning hair and give you a voluminous look. Learn more in our guide to hairstyles for thinning hair or ask your hairstylist. The best hair care approach is typically to use hairstyles and volumizing shampoo for fuller-looking hair in the short term, while also starting a hair loss treatment like finasteride to stop any hair loss and promote hair regrowth in the long term.

What kind of conditioner should I use with a volumizing shampoo?

Adding a volumizing conditioner to your hair care routine can promote long-term nourishment and plump up hair strands. Ingredients like biotin, hydrolyzed rice protein, or argan oil are all top conditioning ingredients that support healthy hair.

Our volumizing conditioner contains biotin to support stronger locks and rice protein to maintain moisture. To give your hair the volume it craves, check out our volumizing conditioner.
