Abstract

Scalp injections and microneedling both are treatment methods that cause pain and discomfort during the procedure and the majority of patients require or demand a form of anesthesia to ease the discomfort. Non-invasive methods for pain reduction during dermatological procedures include topical anesthetic drugs, skin cooling, and vibration. Skin cooling can lower the skin temperature during procedures, and thereby improve pain and discomfort (cryoanalgesia).
Method: Patient is asked to wear a frozen hypothermic gel helmet or Cryo-cap cooled in the refrigerator for 20-30 minutes before the procedure.  Then we remove the cap and start immediately the injections .
Results:Subjective improvement in pain threshold and good patient tolerance during scalp microneedling which allowed us to perform faster during the treatment sessions.
 simple, effective and it helps to avoid local anesthesia risks as well as its discomfort, and allows faster performance.
Conclusion:Cryo-caps or hypothermic gel helmets are simple yet effective technique to avoid local anesthesia risks as well as its discomfort, and allows faster performance
