Luxury hair serums: lengths or scalp application

Identifying the target before purchasing
A serum applied to lengths to support styling differs from a formula intended for the scalp. The same product term therefore covers uses that are not interchangeable. Examine the area, highlighted ingredients and any rinsing instructions so a treatment is not redirected towards an application outside the one described by its manufacturer.
Separating appearance from hair-loss assessment
Hair that looks denser or more coated does not necessarily mean that its number has increased. Read claims according to the outcome actually assessed by the brand. Sudden shedding, patches or persistent discomfort call for professional evaluation; a cosmetic serum cannot establish the underlying cause of those changes by itself.
