Ease of Application
91%
The shaker bottle design is highly praised for making the application quick and straightforward. Users find it easy to achieve a precise and even distribution of fibers, even on hard-to-reach areas like the hairline or crown of the head.
That said, some buyers wish for a sifter attachment for more control and less mess, as the shaker can sometimes spill too much product if not handled carefully.
Natural Finish

Most users love the natural finish this product provides. The fibers stay in place without clumping or looking artificial, blending well into the hair color for a subtle, fuller look that doesn’t appear powdery or overly done.

Many buyers report that the fibers stay intact for several hours, even through normal activities like working or walking outdoors. The water-resistant formula helps maintain the look throughout the day without frequent touch-ups.

Water-Resistance
88%
Users are generally satisfied with the product’s water-resistant properties, as it ensures that the fibers remain in place during moderate sweating or rain. This makes it a great option for daily wear or use during physical activities.
Nonetheless, a few reviewers mention that while it resists minor moisture, the product can begin to break down after extended exposure to heavy rain or extreme perspiration, causing some of the fibers to loosen.
Confidence Boost

While most are satisfied with the value, some buyers feel the price is a bit high compared to other similar products, particularly for those who may need to buy the product frequently.
Clump Resistance
91%
The product’s clump-resistant formula is a standout feature, ensuring that the fibers are evenly distributed across the hair without forming visible clumps. This results in a smoother, more natural finish that doesn’t appear heavy or artificial.
Despite the clump resistance, a few users still mention that the product can sometimes clump slightly if applied too heavily or without sufficient blending, particularly on very fine hair.
Satisfaction with Refill Size
87%
The 100g refill is seen as a convenient and long-lasting option, particularly for users who rely on the product daily. It’s large enough to cover extended periods of use, providing more value than smaller alternatives.
