Gifted to parents/spouse to avoid salon dyeing
A very large share of reviews describe buying the product for mothers, fathers, or husbands who are bothered by frequent hair dyeing or want a low-maintenance alternative.
Alternative for dye-allergic users
Multiple reviewers specifically state they or a family member are allergic to chemical hair dyes or henna and chose this shampoo as a safer substitute.
Word-of-mouth and hype-driven trial
Several buyers say they purchased after reading many positive reviews or hearing about the product's reputation, sometimes skeptically at first.
Repeat/subscription-style repurchasing
Numerous 3rd-5th time repurchase comments indicate satisfied customers keep reordering once they see gradual results, often stocking up during sales.
Value/bundle size and free trial sachets
Reviewers note the large 300g bottle plus 10-day trial packets offer good value for money, especially when bought during Olive Young promotions.
