What Does Trichoscopy Show for CCCA Scalp Loss and Scarring?

When you visit a dermatologist for hair loss, they will often examine your scalp using a specialized handheld magnifier with a bright light. This tool is called a dermatoscope, and the pain-free process of examining the hair and scalp with it is known as trichoscopy.

Trichoscopy allows your doctor to see microscopic details on your scalp that are invisible to the naked eye. In cases of Central Centrifugal Cicatricial Alopecia (CCCA), this magnified view helps doctors spot early signs of hair follicle damage, assess whether inflammation might be active, and look for clues that distinguish CCCA from other types of hair loss.

While it is a very helpful tool, findings can overlap with other conditions. A biopsy—a small skin sample taken using a local anesthetic—may still be needed to confirm the diagnosis if the findings are not completely clear ^[1][2].

Here are common features your doctor may look for when they examine your scalp:

Peripilar White Halos

A frequently reported and useful clue in CCCA is the presence of a peripilar white-gray halo ^[3][4]. “Peripilar” simply means “around the hair.” This refers to a distinct, tiny white or grayish ring that surrounds the base of a single hair shaft where it exits the scalp. These halos are often seen alongside small, broken hairs ^[3][4].

However, seeing a halo does not automatically diagnose CCCA. Because these features can overlap with other scarring alopecias or traction alopecia (hair loss from tight pulling), your doctor will interpret them alongside your medical history and the overall pattern of your hair loss.

Perifollicular Erythema (Redness) and Scale

Your doctor will also look for signs of active inflammation around the hair follicles. This can show up as perifollicular erythema (redness around the base of the hair) or as small flakes of skin (scale) ^[4].

While these signs can support the presence of active inflammation in CCCA, they are not always visible ^[4]. The absence of redness or scale does not mean the disease is inactive, as CCCA can sometimes be active with no visible symptoms. Heavy scaling or redness is often more prominent in other types of scarring hair loss, such as lichen planopilaris or discoid lupus (which are autoimmune conditions that can also cause scarring hair loss) ^[5].

Loss of Follicular Ostia (Pores)

Every hair grows out of a tiny opening in the scalp called a follicular ostium (often simply thought of as a pore). In scarring alopecias like CCCA, inflammation gradually destroys the hair follicle and replaces it with scar tissue. When this happens, the opening disappears permanently ^[6][7].

Under the magnifier, areas of established scarring look like smooth, solid patches of skin where no pores are visible ^[6]. Recognizing this lack of follicular openings helps support the conclusion that the hair loss is a scarring (cicatricial) type rather than a temporary, non-scarring type ^[6]. This distinction is critical for treatment: while preserved follicles may still respond to therapy, follicles replaced by scar tissue generally cannot regrow hair.

Honeycomb Pigmentation

You may have heard of a pattern called honeycombing or honeycomb pigmentation, which looks like a continuous net or web of brown pigment on the scalp. While it can sometimes be seen during exams for hair loss, research shows that a honeycomb pattern can be a normal background feature of healthy scalps in people with darker skin tones ^[8][9]. Therefore, it is a common but nonspecific finding that cannot diagnose CCCA on its own, and it must be interpreted alongside other clues ^[8].

The Limits of Trichoscopy

Trichoscopy is an excellent way for your doctor to gather clues without causing you any discomfort, but it has limitations. A normal or uncertain examination cannot entirely rule out CCCA, and the findings can sometimes closely resemble other conditions ^[4][10].

Because of this, your doctor will likely recommend a scalp biopsy if the diagnosis is in doubt or if treatment choices depend on distinguishing between different types of scarring hair loss ^[10][11]. The doctor can use the trichoscopy results to help select the most active spot on your scalp to sample, increasing the chance of obtaining a useful biopsy ^[2].
