Big, lasting volume isn’t created with a round brush alone—it’s built in the prep. According to REDAVID Artistic Team Leader Katherine Sims (@katherine_sims_hair), the difference between a blowout that falls flat and one that stays full and airy comes down to what you use and how you use it before the brush even touches the hair. Get her how-to steps below for a luxury blowout. [btc-revealer left-id="831784" right-id="831783"]

After washing and before reaching for volumizers, Katherine applies REDAVID Orchid Oil Dual Therapy Treatment on wet hair from midlengths to ends then brushes through for even saturation. This step helps:
- Repair and strengthen the hair
- Add shine and softness
- Create slip for smoother brushing
- Provide light heat protection

Next comes the star of the show: REDAVID Volumizer Thickening Spray. Katherine applies it generously from roots through ends—not just at the base. “Most people don’t use enough product,” she explains. “Fully saturating the hair is what gives you maximum lift and body."
Unlike traditional root lifters, REDAVID’s Volumizer Thickening Spray builds volume throughout the hair—not just at the base. The formula is powered by:
- Castor oil to strengthen and support scalp health
- Hyaluronic acid to boost hydration and fullness
- Biotin and amino acids to improve density and softness
- Dynagen-R, a protein that mimics natural hair structure for a plumper look
For maximum lift, applying the volumizer in proper sectioning is key. Katherine recommends:
- Working in clean, small subsections
- Elevating each section away from the head
- Maintaining control of the round brush for even distribution of heat and tension
After spraying, use your fingertips to massage the scalp and emulsify the product evenly throughout the hair.

Using a medium round brush focus on two things:
- Elevation: Lift hair up and away from the scalp
- Tension: Wrap hair firmly around the brush
This combination is what creates real volume and movement—not just temporary fluff.

Here’s the step most people skip: letting the hair cool in shape. After drying each section, leave it wrapped around the brush for a few seconds before releasing.“I leave the brush in each section to cool because that’s what really locks in the volume,” says Katherine. This helps:
- Set the shape
- Lock in lift
- Extend the life of the blowout
Pro tip: This technique works across hair types. The key is saturation, tension and setting the shape.
