Lately, I've been really worried about hair loss.

Lately, the amount of hair falling out every time I wash it is unusually severe, so I’m thinking of starting a preventative care routine. How do you all manage this? I’m debating whether supplements or shampoo alone would be sufficient, or if the best solution is to just go to the doctor as soon as possible to get a prescription. If anyone has seen great results from managing their hair from the early stages, please share your routine or tips.
