How can I verify results? Are before-and-after records available?

There is only one method that can be verified: take regular photos at the same angle and with the same light, and compare before and after with fixed detection indicators (such as density and hair follicle status). The records can be viewed and taken away. An agency that is willing to provide records is much more reliable than one that only gives verbal assurances.

At the same time, pay attention to the way of expression: when talking about effects, you must talk about cycles and individual differences, which are more credible; absolute expressions such as "guaranteed", "certain" and "radical cure" are signals to be avoided. Scalp care improves the scalp environment. Conclusions on hair growth should be based on a doctor’s evaluation.
