Tips to Keep Your Hair Looking Amazing After 40

16. Embark on hair loss treatment

When you start to notice some worrying hair changes, such as thinning or balding, consider starting hair loss treatments such as finasteride or minoxidil. Dermatologists often prescribe these treatments, either by prescription or over the counter. The earlier you start, the better. That said, we strongly recommend that you talk to a physician before you start any medicative treatment because while effective, these treatments have some side effects. For example, finasteride may cause depression, impotence, or a diminished sex drive. The earlier you start the treatment, the less frequently you need to use the medication, meaning the less exposed you'll be to potential side effects.
