Does married woman needs to have her head covered while reciting brachot?
Answer:
No, there is no specific obligation for a woman to cover her hair when reciting blessings.
Sources: Concerning covering hair for blessings, see Shulchan Aruch, Orach Chaim 75:2, and Mishnah Berurah 14. This refers only to men who are able to see a woman’s hair as they recite the blessing, but not to the woman herself.
