This precision instrument allows you to spray Toppik on, rather than just shaking it. By using this appliance, you will get an even more natural look with Toppik. The fibers will disperse more evenly and be directed more precisely. Because of this precision, you will find yourself using significantly less Toppik, making this economical as well. The Maximizer is perfect for filling out your front hairline. For best results, use it with the Toppik Hairline Optimizer. Also great to cover up roots and blend hair extensions. Fits both the 12g and 27.5g sizes.
