Jamaican Mango & Lime No More Itch Gro Spray. People who wear locks & twists tend to have itchy scalps because unlike traditional hair styles where the scalp and blood circulation are stimulated by combing or brushing, locks and twists are not combed or brushed. The lack of stimulation causes itching. Jamaican Mango & Lime No More Itch Spray can be used daily to stop the itch and provide moisture to locks and twists. Simply spray the scalp thoroughly first, then to the hair to prevent breakage.
