Suited to people with fine or normal hair that falls flat and needs a volume boost from the shampoo step, including color-treated hair. Not aimed at coarse, thick, or very dry hair — the "light moisturizers" positioning suggests it's not a deeply hydrating formula, so those with dry or damaged hair may find it under-moisturizing.

The appeal here is that the volumizing effort starts in the shower rather than being left entirely to styling products. Instead of just a stripping, high-foam cleanse that leaves hair feeling fuller only because it's been dried out, the shampoo pairs a lightweight lifting polymer with a ceramide component meant to reinforce the hair strand itself, aiming for volume that doesn't come at the cost of feeling coarse or over-cleansed.

Because Matrix has since discontinued this line, it also functions as a "while supplies last" option for anyone who already used and liked the original Vavoom Bust Out system and wants to finish it out or stock up before it's gone for good.

Apply to wet hair

• Work into a lather, focusing on the scalp and roots where most of the volumizing effect is needed
• Rinse thoroughly
• Use in place of a regular shampoo; pair with a lightweight, volumizing conditioner rather than a heavy one to avoid weighing hair back down

Pros

• The weightless styling polymer is specifically meant to lift fine, flat hair rather than just coat it with residue
• Ceramide inclusion is a step beyond a typical bare-bones volumizing shampoo
• Formulated to be safe for color-treated hair

Cons

• Matrix has discontinued the Vavoom line, so stock is limited to what retailers already have on hand and won't be replenished
• No current, verifiable full ingredient list exists from the brand, making it hard to check for specific allergens or sensitivities
• Volumizing/styling polymers can build up on fine hair with daily use if not occasionally alternated with a clarifying shampoo
