Central centrifugal cicatricial alopecia (CCCA) is a scarring type of hair loss. “Scarring” means the hair follicle (the tiny pocket that grows hair) gets damaged and can be replaced by scar tissue, so that hair cannot grow back from that spot. It usually starts on the crown/vertex (top middle) of the scalp and slowly spreads outward in a circle. JAMA Network+3American Academy of Dermatology+3DermNet®+3
Central centrifugal cicatricial alopecia (CCCA) is a type of scarring hair loss that usually starts at the top middle (crown/vertex) of the scalp and slowly spreads outward. “Central” means the center of the scalp, “centrifugal” means it spreads out in a circle, and “cicatricial” means scar-forming. In CCCA, long-lasting scalp infection, or irritation, often causing pain, swelling, heat, or redness. সহজ বাংলা: শরীরের প্রদাহ; ব্যথা, ফোলা বা লালভাব হতে পারে।" data-rx-term="inflammation" data-rx-definition="Inflammation is the body’s response to injury, infection, or irritation, often causing pain, swelling, heat, or redness. সহজ বাংলা: শরীরের প্রদাহ; ব্যথা, ফোলা বা লালভাব হতে পারে।">inflammation can damage the hair follicles so badly that the body replaces them with scar-like tissue, and then the hair may not grow back in those spots. American Academy of Dermatology+2NCBI+2
CCCA is seen most often in Black women, especially adults, but it can also happen in other groups and sometimes in men. Many people notice it slowly over months or years, which is why early diagnosis matters—treatment can help stop more permanent loss, even if it cannot “undo” scarred areas.

How CCCA damages hair
In CCCA, the body’s infection, or irritation, often causing pain, swelling, heat, or redness. সহজ বাংলা: শরীরের প্রদাহ; ব্যথা, ফোলা বা লালভাব হতে পারে।" data-rx-term="inflammation" data-rx-definition="Inflammation is the body’s response to injury, infection, or irritation, often causing pain, swelling, heat, or redness. সহজ বাংলা: শরীরের প্রদাহ; ব্যথা, ফোলা বা লালভাব হতে পারে।">inflammation (swelling and “irritation” inside the skin) mainly targets hair follicles on the scalp. Over time, repeated inflammation can destroy important parts of the follicle, and the body heals by laying down fibrous scar tissue. When follicle openings disappear, the scalp can look smoother and shinier in that area. PMC+3NCBI+3DermNet®+3
CCCA can be tricky because early on you may still see hair, but the follicles are already under stress. That is why dermatologists often use tools like trichoscopy (scalp dermoscopy) and sometimes a scalp biopsy to confirm scarring and infection, or irritation, often causing pain, swelling, heat, or redness. সহজ বাংলা: শরীরের প্রদাহ; ব্যথা, ফোলা বা লালভাব হতে পারে।" data-rx-term="inflammation" data-rx-definition="Inflammation is the body’s response to injury, infection, or irritation, often causing pain, swelling, heat, or redness. সহজ বাংলা: শরীরের প্রদাহ; ব্যথা, ফোলা বা লালভাব হতে পারে।">inflammation before the damage becomes permanent. NCBI+3PMC+3PubMed+3
Other names for CCCA
Hot comb alopecia: This older name was used because early reports linked the condition to hot-comb hair styling, but we now know CCCA can happen even without hot-comb use. Bad+2JAAD+2
Follicular degeneration syndrome: This is another older name used in medical history for the same disease group, focusing on follicle damage and scarring. Bad+1
Chemically induced cosmetic alopecia (older term): This name was used when people believed chemicals were the main cause, but today CCCA is considered multifactorial (more than one factor). Bad+2DermNet®+2
Types of CCCA
Here are common clinical patterns doctors may describe (real people can have overlap). PubMed+3JAMA Network+3DermNet®+3
Classic central/vertex pattern
Centrifugal “spreading circle” pattern
Diffuse crown thinning pattern
Patchy pattern beyond the crown
“Hidden/early” CCCA (biopsy changes with little visible loss)
Advanced end-stage scarring pattern JAMA Network+3PubMed+3PMC+3
1. Classic central/vertex pattern: Hair loss begins at the crown (vertex) and is most noticeable there first. This is the “typical” pattern the name CCCA describes. JAMA Network+2DermNet®+2
2. Centrifugal spreading pattern: The thin area gradually grows outward from the center, like a widening circle. This slow outward spread is a key clue for CCCA. NCBI+2DermNet®+2
3. Diffuse crown thinning pattern: Instead of a sharp bald patch, some people mainly see overall thinning and breakage around the crown area. This can be confused with other hair loss types unless the scalp is examined closely. JAMA Network+2PMC+2
4. Patchy pattern beyond the crown: Some patients show patchy loss outside the vertex area. This is one reason doctors warn that CCCA does not always look “perfectly central.” PubMed+1
5. Hidden/early CCCA: Research has reported biopsy findings consistent with CCCA even when obvious hair loss is not yet visible, meaning early disease can be present before the “bald spot” looks clear. PMC+1
6. Advanced end-stage scarring pattern: In later stages, the follicle openings may be gone in the affected area, meaning regrowth is unlikely there. Treatment focus becomes preventing spread and protecting remaining follicles. American Academy of Dermatology+2DermNet®+2
Causes and risk factors
CCCA does not have one single proven cause. Most experts describe it as a mix of genetics, infection, or irritation, often causing pain, swelling, heat, or redness. সহজ বাংলা: শরীরের প্রদাহ; ব্যথা, ফোলা বা লালভাব হতে পারে।" data-rx-term="inflammation" data-rx-definition="Inflammation is the body’s response to injury, infection, or irritation, often causing pain, swelling, heat, or redness. সহজ বাংলা: শরীরের প্রদাহ; ব্যথা, ফোলা বা লালভাব হতে পারে।">inflammation, and (in some people) hair and scalp stressors. PMC+3DermNet®+3NCBI+3
1. Genetic tendency (family history): CCCA can run in families, suggesting inherited risk in some people. Genetics may make follicles more sensitive to infection, or irritation, often causing pain, swelling, heat, or redness. সহজ বাংলা: শরীরের প্রদাহ; ব্যথা, ফোলা বা লালভাব হতে পারে।" data-rx-term="inflammation" data-rx-definition="Inflammation is the body’s response to injury, infection, or irritation, often causing pain, swelling, heat, or redness. সহজ বাংলা: শরীরের প্রদাহ; ব্যথা, ফোলা বা লালভাব হতে পারে।">inflammation or injury. NCBI+2DermNet®+2
2. PADI3 gene variants (in some families): Studies found variants in PADI3, a gene important for normal hair-shaft formation, in some people with CCCA. This does not explain all cases, but it supports a genetic role. PubMed+2DermNet®+2
3. Chronic follicle infection, or irritation, often causing pain, swelling, heat, or redness. সহজ বাংলা: শরীরের প্রদাহ; ব্যথা, ফোলা বা লালভাব হতে পারে।" data-rx-term="inflammation" data-rx-definition="Inflammation is the body’s response to injury, infection, or irritation, often causing pain, swelling, heat, or redness. সহজ বাংলা: শরীরের প্রদাহ; ব্যথা, ফোলা বা লালভাব হতে পারে।">inflammation: Many descriptions of CCCA emphasize inflammatory changes around follicles. Repeated infection, or irritation, often causing pain, swelling, heat, or redness. সহজ বাংলা: শরীরের প্রদাহ; ব্যথা, ফোলা বা লালভাব হতে পারে।" data-rx-term="inflammation" data-rx-definition="Inflammation is the body’s response to injury, infection, or irritation, often causing pain, swelling, heat, or redness. সহজ বাংলা: শরীরের প্রদাহ; ব্যথা, ফোলা বা লালভাব হতে পারে।">inflammation can lead to scarring over time. NCBI+2JAMA Network+2
4. “chronic injury or inflammation. সহজ বাংলা: অতিরিক্ত দাগের মতো টিস্যু তৈরি হওয়া।" data-rx-term="fibrosis" data-rx-definition="Fibrosis means excess scar-like tissue formation after chronic injury or inflammation. সহজ বাংলা: অতিরিক্ত দাগের মতো টিস্যু তৈরি হওয়া।">Fibrosis-prone” biology (scar-forming tendency): Some resources note CCCA can be seen with a higher tendency toward forming extra scar tissue, which may push the scalp toward fibrosis after inflammation. BAD Patient Hub+1
5. Tight traction hairstyles: Styles that pull tightly on the scalp (strong traction) have been linked in studies as a possible contributor in some people, likely by repeated stress on follicles. JAMA Network+2PMC+2
6. Tight braids and cornrows (when very tight or long-term): These can create ongoing traction and scalp stress, especially if they cause pain, bumps, or broken hairs at the crown. JAMA Network+2DermNet®+2
7. Weaves and extensions (especially if tight/heavy): Added hair can increase pulling and weight on follicles. This may worsen inflammation in a scalp already at risk. DermNet®+2PMC+2
8. Chemical relaxers (possible risk in some studies): Research has not been perfectly consistent, but some studies report an association between relaxer use and CCCA risk in some groups. PMC+2DermNet®+2
9. Heat styling and hot combing: Historically, CCCA was linked to hot comb use; today it is seen as a possible stressor rather than a single cause, because CCCA can occur without it. Bad+2JAAD+2
10. Frequent high-heat blow drying/flat ironing: Repeated high heat can damage hair shafts and irritate the scalp, which may add stress to vulnerable follicles (even if it is not the only trigger). DermNet®+1
11. Scalp infections or folliculitis (inflammation from germs): A major survey-based study suggested that inflammation, including possible bacterial infection, may contribute in some cases. JAMA Network+1
12. Long-term scalp irritation from harsh practices: Repeated rubbing, scratching, harsh brushing, or irritating products can keep the scalp inflamed, which may worsen scarring alopecia processes. NCBI+1
13. Mechanical breakage and repeated trauma at the crown: Constant stress at the crown (where CCCA often starts) may create a “weak zone” where inflammation and scarring become more likely. JAMA Network+2DermNet®+2
14. Autoimmune-style inflammation (immune mis-targeting): Patient information sources describe autoimmune-type factors as a possible mechanism—meaning the immune system may react in a harmful way around follicles. BAD Patient Hub+1
15. Being female (risk factor, not a fault): CCCA is reported far more often in women than men, which may relate to biology and also hair practices—but it can occur in anyone. JAMA Network+2DermNet®+2
16. African ancestry and tightly curled hair types (risk association): CCCA is most common in Black women, suggesting genetic and hair/follicle structure factors may play roles. This is a risk association, not something “wrong” with the hair. JAMA Network+2DermNet®+2
17. Age (often adult onset): Many references describe CCCA most commonly in adults (often middle age), though studies also report it can appear in adolescents. JAMA Network+2MDPI+2
18. Association with uterine fibroids (leiomyomas): Studies in Black women found an association between CCCA and uterine fibroids. This does not prove one causes the other, but may point to shared “fibrosis” pathways. PMC+2BAD Patient Hub+2
19. Possible metabolic links (mixed evidence): Older research suggested links with type 2 diabetes/metabolic issues, but newer work has found weaker or no links for many metabolic conditions. So doctors treat this as “possible but not settled.” JAMA Network+1
20. A combination effect (multi-factor trigger): Many expert summaries conclude CCCA likely happens when a person has a genetic tendency and then experiences repeated scalp stress and inflammation over time. DermNet®+2NCBI+2
Common symptoms and signs
Some people have no strong symptoms at first, so signs on the scalp may be the first clue. Bad.org.uk+2DermNet®+2
1. Slow thinning at the crown: The most common first sign is less hair density on the crown/vertex. It often spreads gradually. JAMA Network+2DermNet®+2
2. Hair breakage (short broken hairs): Many people notice the hair seems to break easily near the crown, even before obvious bald patches form. DermNet®+1
3. Widening part line near the top: The part may look wider because there are fewer healthy hairs growing in that central area. JAMA Network+1
4. Itching (pruritus): Some patients feel itch on the scalp due to inflammation around follicles. Bad.org.uk+2DermNet®+2
5. Burning feeling: A burning sensation can happen when the scalp is inflamed. Not everyone feels it, but it is a known symptom. Bad.org.uk+1
6. Tingling: Tingling can occur as part of scalp sensitivity from inflammation. If tingling is severe or spreads widely, doctors may also check other causes. Bad.org.uk+1
7. Tenderness or soreness: The scalp may hurt when touched, combed, or styled, especially during active inflammation. Bad.org.uk+1
8. Scalp sensitivity to hairstyles: Styles that were once comfortable may start to feel painful, tight, or “too much” around the crown. This can be a warning sign to reduce traction. DermNet®+2JAMA Network+2
9. Redness around follicles: Some people have visible redness (erythema), often around follicle openings, showing active irritation. NCBI+2DermNet®+2
10. Scale around follicles: Fine scale around hairs can be seen in scarring alopecias, including CCCA, and may be picked up better with dermoscopy/trichoscopy. DermNet®+2PMC+2
11. Small bumps (perifollicular papules): Inflammation can produce small bumps around follicles. People may describe a “bumpy scalp” at the crown. DermNet®+1
12. Pustules (pimple-like bumps) in some cases: Some descriptions include follicular pustules, which can suggest stronger inflammation or infection on top of CCCA activity. DermNet®+1
13. Smooth shiny scalp in advanced areas: When follicles are destroyed and replaced by scar tissue, the scalp can look smooth with fewer visible follicle openings. DermNet®+2NCBI+2
14. Loss of follicle openings (“no pores” where hair should be): Clinicians look for loss of follicular openings as a key clue for scarring alopecia rather than simple shedding. NCBI+2DermNet®+2
15. Patchy loss outside the crown (in some people): Although “classic” CCCA is central, published cases show some people have patchy loss beyond the vertex, so pattern alone is not the whole story. PubMed+1
Diagnostic tests for CCCA
Doctors often diagnose CCCA using history + scalp exam, then confirm (when needed) with trichoscopy and biopsy, while also ruling out other causes of hair loss. PMC+3NCBI+3JAMA Network+3
Physical exam tests
1. Scalp pattern inspection: The clinician checks where thinning starts (often crown), how it spreads, and whether it matches a typical CCCA pattern or an atypical one. JAMA Network+2PubMed+2
2. Follicular opening check: The doctor looks closely for missing follicle openings in thin areas. Missing openings strongly suggests a scarring process, not just temporary shedding. NCBI+2JAAD+2
3. Inflammation check (redness/scale/pustules): The scalp is examined for redness, scale, bumps, or pustules that signal active inflammation needing treatment. NCBI+2DermNet®+2
4. Hair density and part-width measurement: Clinicians may measure density and compare areas over time, because CCCA can progress slowly and changes can be subtle. JAMA Network+1
5. Standardized scalp photographs: Photos taken the same way each visit help track progression and response to treatment, especially when changes are gradual. NCBI+1
Manual tests
6. Hair pull test: The clinician gently pulls a small group of hairs to see if many shed easily. This is mainly to check for extra shedding (like telogen effluvium) happening along with CCCA. Europe PMC+1
7. Hair tug test (breakage test): The clinician tugs the hair shaft to see if it snaps, which helps separate hair breakage from true shedding and guides hair-care advice. DermNet®+1
8. Gentle scalp palpation: Touching the scalp checks for tenderness, warmth, or thickened areas that can indicate active inflammation or scarring. Bad.org.uk+1
9. Hairstyle/traction assessment: The clinician checks for signs of traction stress (tension areas, breakage, pain with styles) because traction can worsen inflammation in susceptible scalps. JAMA Network+2PMC+2
Lab and pathological tests
10. Scalp biopsy (punch biopsy): This is one of the most important confirmation tests. A small piece of scalp is examined under a microscope to show scarring, inflammation type, and follicle damage. NCBI+2JAMA Network+2
11. Biopsy site selection using dermoscopy clues: Dermoscopy findings (like the peripilar white/gray halo) can help choose the best biopsy spot, increasing the chance of a clear diagnosis. PubMed+1
12. Histopathology with standard stains (H&E): Pathology uses routine staining to look for scarring (fibrosis), loss of sebaceous glands, and inflammatory patterns typical of scarring alopecia. NCBI+2PMC+2
13. PAS stain or fungal evaluation (when needed): If scale, broken hairs, or patches suggest fungus, labs may use special stains or tests to rule out tinea capitis and similar infections. NCBI+1
14. Bacterial culture (when pustules/crust suggest infection): If pustules or oozing are present, culture can identify bacteria and guide treatment, because infection-related inflammation can worsen disease activity. JAMA Network+1
15. Blood tests to rule out common contributors (case-by-case): Some clinicians check tests like iron/ferritin or thyroid function when the story suggests other hair-loss causes are present too, because more than one problem can overlap. NCBI+1
Electrodiagnostic / computer-based objective tests
16. Trichogram: A trichogram examines plucked hairs under a microscope to estimate hair-cycle patterns and shaft changes. It does not “prove” CCCA alone, but it can support evaluation when shedding/breakage questions exist. Actas Dermo-Sifiliográficas+1
17. Phototrichogram (computer-assisted hair counts): This uses close-up photos over time to count hairs and measure growth changes. It is often used for monitoring and for objective tracking in hair disorders. IJDVL+1
18. TrichoScan (computer-based phototrichogram tool): TrichoScan is a software-assisted method used to measure hair growth parameters more objectively than “just looking,” mainly for tracking over time. PMC+1
Imaging tests
19. Trichoscopy (scalp dermoscopy): This is a key noninvasive imaging method. In CCCA, a well-known clue is the peripilar white/gray halo, plus other scarring patterns, which helps diagnosis and biopsy targeting. PubMed+2PMC+2
20. High-frequency scalp ultrasound / advanced imaging (specialist use): High-frequency ultrasound and other newer imaging methods can help evaluate scarring alopecias and activity in some settings, but they are usually add-ons, not replacements for exam/biopsy. PMC+2PubMed+2
