Keloids expand in claw-like growths over normal skin.<ref>{{cite journal | vauthors = Babu M, Meenakshi J, Jayaraman V, Ramakrishnan |date = July 2005 |title=Keloids and hypertrophic scars: A review |journal=Indian Journal of Plastic Surgery |volume=38 |issue=2 |pages=175–9 |doi=10.4103/0970-0358.19796|doi-access= free}}</ref> They can hurt with a needle-like pain or to itch, the degree of sensation varying from person to person.{{cn|date=July 2022}}

Keloids typically form within [[scar|scar tissue]]. [[Collagen]], used in [[wound repair]], tends to overgrow in this area, sometimes producing a lump many times larger than that of the original scar. They can also range in color from pink to red.<ref>{{Cite web | vauthors = Cole GW | veditors = Stöppler MC | date = 27 July 2022 |title = Keloid Scar: Find Causes, Symptoms, and Removal|url = http://www.medicinenet.com/keloid/article.htm|website = MedicineNet|access-date = 2016-02-11}}</ref> Although they usually occur at the site of an injury, keloids can also arise spontaneously.  They can occur at the site of a [[piercing]] and even from something as simple as a pimple or scratch. They can occur as a result of severe [[Acne vulgaris|acne]] or [[chickenpox]] scarring, infection at a wound site, repeated trauma to an area, excessive skin tension during wound closure or a foreign body in a wound. Keloids can sometimes be sensitive to chlorine.{{Citation Needed|date=January 2024}} If a keloid appears when someone is still growing, the keloid can continue to grow as well.{{cn|date=July 2022}}
