Hair questions,

How does volumizing shampoo and conditioner work?

Most volumizing shampoos and conditioners contain ingredients that create 'hold' to lift hair away from the head. Our volumizing shampoo and conditioner contain 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.

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

Does ‘regular’ conditioner help with volume?

Not necessarily. It depends on the ingredients and your hair type. A good conditioner trusted by both dermatologists and hair stylists alike can help promote hydration that wards off breakage and sets you up to grow healthier hair. We recommend selecting a conditioner to treat and enhance the condition of your hair. When it comes to volumizing, our shampoo and conditioner are lightweight and lift, strengthen and plump hair follicles leaving your mane soft but not flat.

Should I use a volumizing conditioner with a volumizing shampoo?

We recommend using a nourishing conditioner that strengthens your locks. For those looking to really pump up the volume, use Full Volume Conditioner alongside Full Volume Shampoo.

What's the difference between volumizing and thickening shampoo?

Thickening shampoo thickens each strand of your hair by infusing it with protein or collagen. Unlike a volumizing shampoo, thickening shampoo usually includes ingredients to address hair loss, like saw palmetto. Hair thickening shampoo with saw palmetto may help target DHT, the hormone that contributes to hair loss, as well as reducing build up on the scalp.

On the other hand, 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. Volumizing shampoos typically use lightweight ingredients that won’t weigh your hair down at the roots— making it great for those with fine, limp hair.

What is a volumizing conditioner?

Volumizing conditioner restores moisture to your locks while making your hair look fuller. Typically a lightweight formula, volumizing conditioners lift, strengthen and have plumping properties, leaving your mane soft but not flat.

Why do I need a volumizing conditioner?

A volumizing conditioner is a great choice for all hair types including fine hair, curly hair, color-treated hair and oily hair. The right ingredients in a volumizing conditioner can help fine hair appear fuller, more lustrous, and boost scalp health. Our formula balances weightless moisture with strand-strengthening, volume-boosting ingredients that let hair do its thing. Max Volume Conditioner also helps to detangle and fight frizz for easy styling.

Does the shampoo and conditioner help remove excess oil and dirt build up on hair?

Unlike a clarifying shampoo, our sulfate-free shampoo and conditioner gently cleanses build up from dirt, excess oil and product without stripping moisture from hair.
