Is It Permitted to Get a Haircut on Isru Chag?

Greetings,

On Isru Chag of Sukkot, it is permitted. However, Isru Chag of Passover falls during the days of the Omer, and Sephardim are accustomed not to get haircuts until the morning of LaD B'Omer (19 Iyar), while Ashkenazim until the morning of Lag B'Omer (18 Iyar).
