Value-for-Money & Large Capacity
The 1000ml size at competitive pricing is the primary driver—multiple reviewers explicitly state they purchased or repurchased based on cost-per-use efficiency and the ability to use daily without guilt.
Protein Reputation & Damage Repair
Consumers buying this product specifically seek protein-enriched treatments for heat-damaged, dyed, or chemically-treated hair; brand reputation for effective protein formulations influences purchase decisions.
Brand Loyalty & Repeat Purchase
Several reviewers mention prior positive experiences with PARKJUN products or having emptied 5+ bottles, indicating strong word-of-mouth and habitual repurchasing behavior.
Large Format for Household Sharing
Multiple reviews note the product is used by multiple family members (mother, household) over an extended period, making bulk size an attractive purchase factor.
