A supervised release order was also imposed on Emma Clark, 34, of Findlater Court, Dumfries, for seven months.
She pleaded guilty at Dumfries Sheriff Court on Wednesday to seizing one woman by the hair in September last year, repeatedly striking her head against the floor rendering her unconscious and while she lay prone kicking her on the head to her severe injury.
Clark also admitted striking another woman on the head with a bar stool at Chancers Nightclub in March last year and just over three months later punching the same woman on the head.
