Some people find that scalp cooling is not as cold as they expected it to be, or that the cap feels less cool as the treatment continues. This is usually because the body acclimatizes quickly, resulting in a numbing effect rather than a sensation of coldness. You may also find that the first treatment feels a lot colder in comparison to subsequent experiences - often because you know what to expect. If the system is not cooling to the appropriate temperature, it will alert so that your clinical team is aware.
