Word-of-mouth and online buzz
Multiple reviewers say they bought it after seeing it widely recommended online or by influencers, often as a well-known 'holy grail' K-beauty brow product.
Repeat/staple purchase
A large share of reviews are 2nd, 3rd, or 4th repurchases, with several long-term users (some citing years of use) calling it their go-to brow product.
Hard-to-find natural shade range
Reviewers, especially those with black or dark brown hair, note the gray-brown and clear shades are difficult to find in their home markets (e.g., Europe), driving purchase.
Brand trust in hince
Several buyers purchased specifically because they already love hince products and packaging quality, treating this as an extension of a trusted brand line.
Convenient alternative to pencil/microblading
Some reviewers bought it to replace eyebrow pencils, mascara, or even microblading touch-ups for a faster, more natural everyday look.
