How to use
Using the Monster Pump allows you to easily fill in gaps in your hair naturally. Avoid the hairline and scalp and apply it to areas such as partings. Hold the spray 10-15cm away from your scalp and press firmly. Pressing firmly will create a fine mist. Using the Monster Comb will prevent the spray from getting into your face or eyes. It is resistant to rain, wind, and sweat, allowing you to keep your style in place for a long time.

Do you offer express shipping?
Yes. As of 22 July 2026, we offer International Express Mail through Japan Post. The cost is based on order weight and is calculated automatically at checkout.
Will I pay customs or import fees?
US orders: No. As of July 1, 2026, all US orders ship DDP (duties delivered prepaid), meaning we prepay all import duties on our end. Nothing is due at your door.
Orders outside the US: Possibly. Duties and import taxes are set by your local customs authority and are not collected at checkout, so any charges on delivery are your responsibility.
We're working on rolling out prepaid duties for more countries soon.
