Last night before I went to bed I applied S-Curl to my hair and then put a shower cap on to keep in the moisture. Well, I woke up this morning and my scalp felt like it was on fire! I have been scratching ever since. Could it be the glycerine? If so, is there anything that I could add to the S-Curl to alleviate the itching? Is there anything that works just as well as the S-Curl? HELP!!
