Head and Shoulder (mint) and Vaseline really work wonder!!
Itchy scalp and lip is beginning to diminish after trying them out yesterday.
Thanks to nomilk and pj for recommending the above.
Just knew that vaseline is actually 100% petroleum jelly (a mixture of hydrocarbons). And a guy by the name of Cheesebrough realised its commercial potential after discovering this gel from the oil riggers in United States. After developing and refining the gel, this product was promoted as ointment to heal wounds and cuts. However it was later found out that this claim was baseless. The ointment only helped to seal off the wound from the air and prohibits germs and bacterias from entering the wound. Nowadays, petroleum jelly is used widely in skin related products such as cosmetics.
