Hair loss / thinning concerns
The majority of reviewers bought the product specifically to address hair shedding, thinning hair, or a widening hairline/part, often as an ongoing concern rather than a one-time issue.
Word-of-mouth and online buzz
Many buyers mention purchasing after reading glowing reviews or seeing it listed as a top-selling scalp ampoule, indicating strong social proof and viral reputation.
Repeat/repurchase loyalty
A large number of reviews are explicitly repeat purchases (2nd, 4th, 5th bottle, or ongoing use for a year+), showing the product builds a loyal, habitual customer base.
Gifting
Several reviewers bought the set as a gift for family members (mother, grandmother, husband, son), suggesting appeal as a gift item, especially within Asian markets.
Brush applicator design
The convenience of the built-in brush/comb tip (versus messy dropper or hand application) is frequently cited as a key reason for choosing this over other scalp serums.
