I've got an early stage of hair loss. What can be done to halt it?
More than before
If it's a genetic pattern of hair loss, minoxidil, Finasteride (prescription) and laser therapy (lasercap, laser brushes) can help, and the sooner you start the better. See a specialist in genetic hair loss to discuss the options.
If it's caused by another condition, you need to see a doctor to get the right diagnosis and get treated.
