Viral TikTok/social media exposure
Many reviewers explicitly say they purchased after seeing the product 'all over TikTok' or social media, often citing viral before/after videos as the reason to try it.
Repeat purchase / loyalty
A very large share of reviews are 2nd, 3rd, 4th, 5th or even 6th purchases, indicating strong repurchase intent once initial results are seen.
1+1 bundle value
Several buyers specifically mention the '1+1 set' or 'brilliant value' of the bundle as a reason to buy, seeing it as a good deal to trial or stock up.
Gifting
Reviewers bought the product as gifts for family members (dad, mom, husband, boyfriend, friend) experiencing hair thinning, suggesting gifting is a secondary purchase occasion.
Word-of-mouth / recommendation
Some buyers cite recommendations from friends, family, or general positive reviews as their trigger for purchase, rather than direct advertising.
