women: Is head messages safe for pregnancy?Yes, it is. It promotes deep relaxation for you and your baby, It reduces your heart rate and has increased the capacity of breath in your overall body. There are no contraindication points on the head.
The only precaution i would advise is pushing down in terms of your shoulder. That is one containidication point by pushing down but otherwise any other particular areas of the head is not contraindicationed for message. so hopefully that answers you questions in regard to safety of head messages during your pregnancy.
