If the needles are brown, but the branches are still pliable and a dark wet looking green just underneath the bark, the branches are still alive and can generate new needles. If the tops are dead, nothing can be done besides removal which will encourage regrowth including a new leader from the remaining living parts. Keep up on the soil moisture for all your plants, watering before there is a drought period and be sure to water late in the season as cold weather approaches.
