Upon takeoff from DCA RWY 1 we received a wind shear warning between 400 and 600 feet. As the flying pilot I followed flight director commands until such time as the warning desisted and I felt we were no longer in any danger of losing airspeed. At that time I initiated a visual return to a flight path over the river and rejoined the departure between ADAXE and BEBLE. We then notified ATC we had responded to a [Windshear] warning.  ATC later requested we contact Potomac TRACON which we did on arrival. The Controller at the TRACON informed me I had penetrated P56. I felt it was safer to maintain a direct flight path as opposed to making the turns until I was certain we were clear of any further wind shear issues.While I have no desire to violate a prohibited area I feel the decision to continue wings level in this case was an appropriate action. Perhaps a more aggressive return to our charted flight path would have prevented the entry to P56 but my primary concern was ensuring no further wind shear would [affect] the aircraft; or the safety of our passengers.
After departing DCA Runway 1; a CRJ-200 pilot reported encountering a windshear warning and remained wings level while following the flight director commands. The crew was notified P56 was violated but felt safety required caution at their low altitude.
