Damaged/color-treated hair repair claim
Many buyers with bleached, dyed, or heat-damaged hair purchased specifically hoping to repair damage, and numerous reviews confirm noticeable softness and reduced breakage after continued use.
Scent reputation
A large share of reviews mention buying or repurchasing primarily because of the floral/fruity scent, with several noting compliments from others and long-lasting fragrance.
Repeat purchase / brand loyalty
Extremely frequent mentions of 'second/third/multiple repurchase' show many buyers return to this SKU as a staple rather than trying alternatives.
Line-use with treatment/oil
Several reviewers bought the shampoo after trying the UNOVE treatment or mask, or to complete a full routine set, indicating strong cross-line pull.
Word-of-mouth / social media discovery
Some reviewers cite seeing the product on SNS or being sent samples/gifted bottles before deciding to buy, and mention it being a top seller at OliveYoung.
