What exactly is the "Inside Lock technology" used in the Gatsby Inside Lock series?

The Inside Lock ingredients (ketoglutaric acid) permeates hair, setting your hair from the inside and outside. This new technology allows you to maintain both a natural feel and style.

Containing diatomaceous earth, it prevents your hair style losing out to humidity, maintaining it for long periods of time.

What is more, it washes out easily in warm water, making it perfect for those who have trouble removing wax from their hair, even when rinsing with shampoo.

Please visit the Research & Development for detailed explanation of Inside Lock technology.

Please also visit the Gatsby website for more information on product features, finishing styles, and video tutorials. (in Japanese only)
