Causes of Scalp Keloids · Los Angeles
What Causes Keloids to Form on the Scalp?
Scalp keloids arise after a range of skin injuries in patients who are genetically predisposed to overactive collagen production. Understanding the cause helps guide treatment and future prevention planning.
Acne Keloidalis Nuchae
Acne keloidalis nuchae is a chronic inflammatory skin condition affecting the posterior scalp and nape of the neck that leads to the formation of keloid-like papules and plaques. It is most common in men of African descent but can affect any patient. Without treatment it can progress to large, confluent keloid plaques covering the entire back of the scalp. Dr. Karamanoukian evaluates and treats this condition at Kare Plastic Surgery in Los Angeles. Call (310) 998-5533.
Hair Transplant Surgery Scars
Hair transplant procedures using the strip method produce a linear scar across the back of the scalp. In patients predisposed to keloid formation, this scar can develop into a raised, firm keloid that is visible through the hair and may cause itching or discomfort. Dr. Karamanoukian treats hair transplant keloids with careful surgical revision combined with postoperative adjuvant therapy to minimize the risk of a larger keloid developing in its place.
Scalp Lacerations and Surgery
Any surgical incision or laceration of the scalp can trigger keloid formation in susceptible patients. Neurosurgery, scalp tumor removal, and traumatic scalp wounds are all potential triggers. Patients with a personal or family history of keloid formation should inform their surgeon before any scalp procedure so that preventive measures can be discussed.
Folliculitis and Scalp Infections
Chronic folliculitis of the scalp, a recurring infection or inflammation of the hair follicles, can damage the scalp skin repeatedly and trigger keloid formation over the affected areas. Each episode of inflammation adds to the total burden of collagen overgrowth and can contribute to enlarging keloid plaques over time.
Genetic Predisposition
Keloid formation has a strong genetic component. Patients with first-degree relatives who have keloids face a significantly elevated personal risk. While no specific gene responsible for keloid formation has been identified, the tendency to form keloids is clearly inherited. Patients in high-risk populations benefit from proactive counseling before undergoing any scalp procedure.
Earring and Piercing Keloids
Piercings near the hairline, temple, or upper ear can trigger keloid formation that extends into the adjacent scalp skin. These keloids can grow significantly larger than the original piercing wound and require the same combination approach used for other scalp keloids. Early treatment after noticing an enlarging scar around a new piercing typically produces better results than waiting until the keloid has matured.

Dr. Karamanoukian's Approach to Scalp Keloid Treatment
Keloid surgery carries a recurrence rate of up to 90 percent when excision is performed alone. This is why Dr. Karamanoukian uses a combination approach that pairs surgical removal with adjuvant therapies designed to suppress the collagen overproduction that would otherwise cause a new and sometimes larger keloid to form. The specific combination of treatments is chosen based on the size, location, and history of the keloid as well as the patient's individual risk profile.
Surgical Excision
Surgical removal of the keloid provides the most direct reduction in scar volume. For scalp keloids, Dr. Karamanoukian plans the excision carefully to minimize tension on the wound closure, since tension during healing is a major driver of keloid recurrence. Small, carefully placed incisions are used and the wound is closed in layers to reduce the tension placed on the surface scar. For very large or complex scalp keloids, staged excision may be preferred to remove the keloid in planned steps that reduce the total wound area at any one time.
Steroid Injections
Intralesional triamcinolone injections are a cornerstone of keloid treatment at Kare Plastic Surgery. Injected directly into the keloid, corticosteroids suppress the fibroblast activity responsible for excess collagen production and reduce the inflammatory response that drives keloid growth. A series of injections is given at intervals of four to six weeks, and injections are frequently used both before surgery to soften the keloid and after surgery to reduce the risk of recurrence. For small scalp keloids, injections alone can produce meaningful flattening and symptom relief without surgery.
Postoperative Radiation
Combining surgical excision with postoperative radiation therapy significantly reduces the recurrence rate for keloids compared to surgery alone. Radiation is typically administered in the days immediately following excision, when the wound is most susceptible to new keloid-forming activity. Dr. Karamanoukian coordinates with radiation oncology colleagues to deliver this adjuvant therapy when it is indicated for larger or previously recurrent scalp keloids. Radiation is focused precisely on the treated area to minimize any broader exposure to surrounding tissue.
Laser Therapy
Laser treatment can reduce the redness, thickness, and texture of scalp keloids. Pulsed dye laser targets the blood vessels within the keloid, reducing its blood supply and slowing its growth. Fractional laser treatments can improve the surface texture and reduce the raised profile of the keloid over a series of sessions. Laser therapy is most effective for early or smaller scalp keloids and is frequently combined with steroid injections for an additive effect. Dr. Karamanoukian selects the most appropriate laser protocol for each patient's skin tone and keloid characteristics.
Silicone Therapy
Silicone sheets and silicone gel have been shown to help flatten and soften both new and established keloids by maintaining moisture and pressure on the scar surface. They are used as part of a comprehensive treatment plan, particularly in the postoperative period following excision. Dr. Karamanoukian recommends silicone therapy as a convenient and safe adjuvant that patients can use at home between clinic visits to support the results of their in-office treatments.
Imiquimod for Recurrence Prevention
Imiquimod, an FDA-approved topical medication that modifies the immune response, has been shown in studies to help reduce the risk of keloid recurrence after surgical removal. Dr. Karamanoukian may recommend topical imiquimod as part of a postoperative protocol for patients with a strong history of keloid recurrence, including those who have had prior keloid surgery that regrew. This medication works by altering the local immune environment in the treated scar to suppress the activity of keloid-forming fibroblasts.

"Scalp keloids are among the most difficult scars to treat because surgery alone almost always leads to recurrence. I approach every scalp keloid as a combination problem that requires a surgical foundation supported by the right adjuvant therapies. The treatment plan has to match the individual patient and their specific history, not just the size of the keloid in front of me."

Frequently Asked Questions
What causes keloids to form on the scalp?
Scalp keloids form when the skin responds to an injury by producing far more collagen than needed to heal the wound. Common triggers include hair transplant surgery incisions, scalp lacerations, folliculitis, acne keloidalis nuchae, surgical procedures on the scalp, and piercings near the hairline. Keloids are more common in patients of African, Asian, Hispanic, and Mediterranean descent and tend to have a genetic component. Dr. Raffy Karamanoukian at Kare Plastic Surgery in Los Angeles evaluates and treats scalp keloids. Call (310) 998-5533.
Can scalp keloids be surgically removed?
Yes. Surgical excision is the most direct way to reduce a scalp keloid, and it is most effective when combined with additional therapies to lower the risk of recurrence. Surgery alone carries a recurrence rate of up to 90 percent for keloids, which is why Dr. Karamanoukian combines excision with steroid injections, radiation therapy, laser treatment, or silicone therapy depending on the size and location of the keloid and the patient's history. Call (310) 998-5533.
What is the recurrence rate for scalp keloids after treatment?
Surgery alone for keloids carries a recurrence rate of up to 90 percent. Combining excision with postoperative radiation therapy and steroid injections significantly lowers this rate. Dr. Karamanoukian at Kare Plastic Surgery in Los Angeles designs each scalp keloid treatment plan to minimize the likelihood of recurrence using combination therapy tailored to each patient's specific keloid characteristics and history. Call (310) 998-5533.
Can steroid injections alone treat a scalp keloid?
Steroid injections can flatten and soften scalp keloids, especially in smaller or earlier-stage lesions. They work by reducing collagen production and the inflammatory activity within the keloid. Most patients require a series of injections spaced four to six weeks apart. For larger or well-established scalp keloids, injections alone may not achieve the desired result and are most effective when combined with surgery or laser therapy. Dr. Karamanoukian at Kare Plastic Surgery evaluates each keloid individually and recommends the appropriate combination. Call (310) 998-5533.
Are scalp keloids the same as hypertrophic scars?
No. Hypertrophic scars are raised scars that stay within the boundaries of the original wound. Keloids extend beyond the original wound boundary into surrounding normal tissue and tend to continue growing over time. This distinction is important because keloids require more aggressive combination treatment and carry a significantly higher recurrence risk after surgery than hypertrophic scars. Dr. Karamanoukian evaluates each patient's scar carefully to distinguish between the two before recommending treatment. Call (310) 998-5533.
