The last step of any style sets the tone for everything that follows. A good hair spray locks in what you have created without changing how it feels. No stiffness, no crunch, no hair that looks finished but feels like armour. Just hold onto what works with your style, not against it.
The Number 4 Hair Spray collection keeps it focused. Two high-performance formulas, each designed for a different moment in the styling process, so your hold is always exactly what the style needs.
For the best results, many people use both. Non Aerosol during the styling process and Mighty to seal the finished look.
Flexible styling resins deliver hold and memory without stiffness or flaking. Conditioning agents keep hair soft and protected through the day. Both formulas are vegan, sodium and sulfate-free, paraben-free, cruelty-free, and made in the USA.
