Hair and beard behave differently, and thinning shows up in different places. This tells us which of our three lines to look at.

Different concerns need different actives. This is the single biggest factor in what we recommend.

Cosmetic care works gradually and suits early, gradual changes best. A sudden or recent change is worth showing to a doctor.

Hair changes with age — density, oil production and growth cycles all shift. It helps us set realistic expectations.

Hard water and dry heat affect scalps differently. Knowing yours tells us whether to pair the serum with a cleanser.

Cosmetic care needs consistency to show. A single bottle is a good trial; a multi-month course is what most people see change with.
