What works against it
6Substances used against it. Descriptive — not a recommendation to take them.
What you can do yourself
No compound involved — the part that comes down to dose, training and everyday habits. Often the larger lever, and always the cheaper one.
Early or not at all
A lost follicle does not come back. Everything available works on keeping what is still there.
Photograph it
Same light, same angle, months apart. The mirror is useless for a change this slow.
Know your family
Without the genetic predisposition very little happens. With it, the choice of compound decides how fast.
How you notice it
Your own photos in the same light, months apart. Density at the crown and hairline moves too slowly to judge in the mirror.
