Ice after PRP will affect the ability of the PRP to diffuse. If one uses the subdermal depo injection technique, ice is not necessary since there is a minimal amount of swelling. Ice is not part of our post treatment protocol.
Ice should be unnecessary after PRP scalp injections for hair loss. The small amount of volume of PRP in each injection that soon dissipates into the scalp should not cause swelling that would require any treatment.
