The Frustration of Hair That “Won’t Grow”

Many of us know the frustration of feeling like our hair simply won’t grow past a certain length. We see evidence everywhere—on our clothes, pillows, and in the sink, in the form of short, broken hair pieces. Is it hair loss or breakage? This experience often raises a crucial question that can be difficult to answer: Are these hairs falling out from the root, or are they snapping off somewhere along the strand?

This is more than just a matter of curiosity; it’s a critical diagnostic question. The answer determines your path forward. Are you dealing with hair shedding, a potential medical issue rooted in the scalp? Or are you facing hair breakage, a structural problem related to hair care and styling? Understanding this difference is the first and most crucial step toward finding the right solution. One path leads to changes in your hair care routine, while the other requires prompt medical attention to prevent permanent hair loss.

1. Differentiating the Two Main Culprits: Shedding vs. Snapping

While “hair loss” is a common catch-all term, from a clinical perspective, it’s vital to know if hair is falling from the follicle or breaking along its length, as these are fundamentally different processes with distinct causes and solutions.

What is Hair Shedding?

Hair shedding, clinically known as alopecia, occurs when the entire hair strand, including its root, is released from the follicle in the scalp. This is a follicle-level event, signaling an issue with the hair’s growth cycle or the health of the follicle itself.

What is Hair Breakage?

Hair breakage happens when the hair shaft—the visible part of the hair—snaps or fractures somewhere along its length. The root remains securely in the scalp, but the strand’s integrity has been compromised. This is a hair shaft issue, usually caused by weakness or damage.

To make the distinction clear, here is a simple comparison:

Characteristic	Hair Shedding (Alopecia)	Hair Breakage
What Happens	Entire hair falls out from the root.	Hair shaft snaps off along its length.
The Cause	An issue with the hair follicle or scalp.	Weakness and damage to the hair strand.
The Result	A complete hair strand is found.	A partial hair fragment is found.

Fortunately, there is a simple at-home test you can perform to get a better idea of which issue you might be facing.

The “Bulb Test”: Your First At-Home Clue

This is perhaps the most practical and empowering step you can take right now to investigate your hair concerns. The “Bulb Test” is a simple, immediate way to gather clues about what’s happening with your hair.

Here’s how to do it:

1. Collect a few hairs that have come out. The best samples are from your brush, comb, or pillow, rather than hairs pulled directly from your scalp.

2. Isolate one strand and hold it up against a contrasting background, like a white piece of paper or a light-colored wall.

3. Examine both ends of the hair strand very closely. You may need good lighting.

Analyzing the Results

There are two primary outcomes, each pointing toward a different cause:

• If you see a small white bulb: That tiny bulb is part of the hair root. Its presence indicates that the hair has completed its life cycle and has been shed entirely from the follicle. If you find many hairs with bulbs, it suggests a shedding issue or alopecia.

• If you see no bulb: The absence of a root bulb means the hair likely snapped off somewhere along its shaft. The ends may appear jagged, uneven, or even split, resembling the tip of a broom. This result points toward hair breakage.

Understanding the result of this simple test opens the door to exploring the specific causes behind either breakage or shedding, allowing you to focus your efforts where they will be most effective.

A Deeper Dive into Hair Breakage

If you performed the bulb test and found hairs without roots, your focus should be on understanding why your hair shafts are becoming weak. This damage is often the result of “weathering”—the cumulative stress your hair endures from daily care, styling, and environmental exposure.

For individuals with Afro-textured hair, certain practices are strongly associated with increased breakage due to the hair’s unique structure:

• Chemical Processing: Relaxers work by altering the hair’s internal structure, which can significantly weaken the shaft and make it more susceptible to snapping.

• Heat Styling: Frequent use of high-heat tools like flat irons and blow-dryers can cause cracks in the hair’s protective outer layer, the cuticle, leading to weakness and fracture.

• Mechanical Stress: Aggressive combing, brushing curls while they are dry, and high-tension styles (like very tight braids or ponytails) create physical stress points that can easily lead to breakage.

One of the most common diagnoses related to this issue is Trichorrhexis Nodosa (TN). This is a hair-shaft disorder in which weak points, or “nodes,” form along the hair shaft. Under a microscope, these weak points look like two tiny paintbrushes pushed end-to-end, with the hair shaft frayed and fractured. This is the clinical diagnosis behind the frustrating feeling that your hair “won’t grow past a certain length.” The growth from your scalp is happening, but the accumulated damage causes the strands to snap off at the same rate.

Understanding True Hair Shedding (Alopecia)

For those who found hairs with bulbs, the focus must shift from the hair strand to the scalp and the hair follicle. This type of hair loss requires a prompt medical diagnosis and a targeted treatment plan to slow its progression and, importantly, prevent it from becoming permanent. In Black women, two forms of alopecia are widespread.

Central Centrifugal Cicatricial Alopecia (CCCA)

CCCA is the most common form of scarring alopecia affecting Black women, with studies indicating it affects between 3% and 6% of this population, though some estimates are as high as 15%. It typically begins at the crown of the head and spreads outward in a circular pattern. Symptoms can include itching, burning, and tenderness on the scalp. The itching, burning, and tenderness are not just uncomfortable—they are signs of active inflammation that is attacking and destroying the hair follicles. The most critical feature of CCCA is that it leads to the permanent destruction of hair follicles, which are replaced by scar tissue.

Traction Alopecia

This form of hair loss is caused by chronic, prolonged tension on the hair follicles. It is extremely common, affecting approximately one-third of women of African descent. The main culprits are hairstyles that pull on the hair root for extended periods, such as tight braids, weaves, locs, and ponytails. If the tension is removed early, the hair can often regrow. However, long-standing traction can lead to permanent follicle loss.

It’s important to note that severe breakage happening very close to the scalp can sometimes mimic the appearance of early CCCA. This overlap highlights why the “bulb test” is such a valuable first step and why a professional evaluation is essential for an accurate diagnosis.

The Critical Crossroads: Your Action Plan

Now that you have a better understanding of the difference between shedding and snapping, you can create a clear plan. Your next steps depend entirely on what you’ve discovered about your hair.

If You’re Experiencing Breakage…

The solution lies in modifying your hair care routine to minimize stress and maximize moisture. The goal is gentle handling to preserve the integrity of the hair shaft.

• Gentle Cleansing: Use moisturizing, sulfate-free shampoos to avoid stripping your hair of its natural oils.

• Strategic Detangling: Only detangle your hair when it is wet and saturated with conditioner. Use your fingers or a wide-tooth comb, starting at the ends and working up to the roots.

• Reduce Tension: Opt for low-tension styles like loose twists, braids, or updos. Avoid any style that causes pain or pulling on your scalp.

• Minimize Heat: Limit the use of flat irons and high-heat blow-dryers. When you do use heat, always apply a heat protectant first.

If You’re Experiencing Shedding…

Your next step is clear and non-negotiable: consult a board-certified dermatologist. It is essential to understand that conditions like CCCA are progressive and irreversible once scarring occurs. The window to save your hair follicles is when the inflammation is active, but before the follicle is permanently destroyed. This is why immediate consultation with a dermatologist is not just a recommendation—it is the only practical course of action. Because CCCA is driven by inflammation, the primary goal of medical treatment is to use potent anti-inflammatory medications to stop follicular destruction and preserve hair that has not yet been permanently lost.

Knowing the difference between a “snap” and a “shed” is empowering. It transforms a vague concern into a specific problem that you can begin to solve. By using the simple “bulb test” as your starting point, you are now equipped to stop treating a medical condition with hair products or a hair care issue with unnecessary worry. By taking the proper proactive steps—whether that means refining your wash day routine or scheduling a crucial medical appointment—you are taking control of your hair’s future.
