Will the brown tips turn green again?

No, the brown parts are dead tissue and will not recover. You can trim the brown edges with clean scissors if you dislike the look.

Does tap water cause brown tips?

Sometimes, high mineral content in tap water can cause salt buildup that leads to brown tips. Try using filtered or rainwater for a few weeks to see if it helps.

American senna: brown tips, causes and fixes

Check these first

Check if the soil has pulled away from the sides of the pot.
Measure the humidity level in your room.
Feel if the brown tips are dry and brittle.

Likely causes

Low Humidity
Possible
How to tell: The tips of the leaves become dry, crispy, and brown while the rest of the leaf looks healthy. This often happens in dry indoor air.
What to do: Group your plants together to create a more humid microclimate. You can also place a tray of water and pebbles near the plant to increase local moisture.
Inconsistent Watering
Possible
How to tell: The soil becomes bone dry for long periods, causing the plant to struggle to transport water to the leaf edges. The tips turn brown and brittle.
What to do: Water your plant every 5 to 10 days, ensuring the soil stays consistently moist. Do not let the soil dry out completely between waterings.
