I have made a fair amount of luxury purchases in my life from Dior, Channel, Cartier, Fendi, Celine, VCA and Cartier. I do not remember a single time they have offered a sample like beauty samples. But all the on-boxing videos I see in tiktok from these luxury brands always include a small sample. How is that?

Has any of you tried any hair serums for LPP? I am currently on a lot of meds for LPP including minoxidil but for some reason I think other hair serums might help too. Any safe effective serums you may recommend?
