Start with the good news, because it is almost always true: your hair is growing.
It grew about half an inch last month. It will grow about half an inch this month. That rate holds across ethnicities and hair types, per figures reviewed by the American Academy of Dermatology, and it is remarkably difficult to change. Follicles that have genuinely stopped producing hair are a specific medical situation, not the everyday experience of hair that seems stuck.
So if your hair has been the same length for two years, the question is not "why has it stopped growing." The question is "where is it going." And there are eight realistic answers, ranging from a fixable routine problem to a genetic ceiling you cannot move.
This guide walks through all eight and more usefully how to tell which one is actually yours. Some have straightforward fixes. Some need a doctor. One of them is not a problem at all, just a misunderstanding about how measurement works.
1. Breakage — the answer for most people
This is the cause for the large majority of people who feel stuck, particularly with 4C and coily hair. Your roots produce roughly half an inch a month; your ends snap off at roughly the same rate. Net visible change: zero. Peer-reviewed research indexed on PubMed consistently identifies mechanical damage and moisture loss, not follicle failure, as the primary driver of length loss in Afro-textured hair.
How to tell if this is you: short broken hairs on your shirt, pillow, or bathroom floor (broken hairs have no white bulb at the end; shed hairs do). Ends that look thin and see-through compared to your roots. Single-strand knots. Hair that snaps during detangling. Length that looks the same but hair that feels thinner at the bottom.
What actually fixes it: sealing moisture into the strand so it stays flexible rather than brittle, and eliminating the mechanical stress that snaps it — dry detangling, cotton pillowcases, tight styles, weekly heat. This is the entire premise of a chebe-based routine, and it is why the moisture retention guide matters more than any growth product. The six habits that grow Black hair covers the full anti-breakage framework.
2. Product buildup blocking moisture
Layers of styling product, heavy oils, and grease accumulate on the scalp and strand over weeks. On the scalp it causes itching and flaking; on the strand it forms a barrier that blocks moisture from getting in, which means every moisturising step in your routine gets progressively less effective while you use progressively more product.
How to tell if this is you: your products stopped working after a couple of months. Hair feels coated but never actually soft. Scalp itches within days of washing. Water beads on your hair rather than soaking in.
The fix is a monthly clarifying wash alongside your regular gentle cleansing. Simple, and skipped by almost everyone. The winter scalp care guide covers the buildup cycle in detail, since cold months are when it compounds fastest.
3. A scalp that is inflamed, dry, or neglected
Every hair you grow emerges from your scalp. A scalp that is chronically dry, irritated, inflamed, or under-circulated produces weaker hair from the moment it forms, hair that is more fragile and more likely to break before it accumulates length.
How to tell if this is you: persistent itch, flaking, tenderness, tightness after washing, or scalp discomfort that has become normal background noise.
The fix: gentle regular cleansing, scalp massage two to three times weekly, a lightweight scalp oil, and addressing irritation early rather than living with it. The scalp care guide has the full routine. One caution, persistent tenderness or pain at the crown is not ordinary dryness and warrants a dermatologist.
4. Nutritional deficiency — the cause most people never check
Hair is a low-priority tissue. When your body is short of a key nutrient, it allocates to organs, blood, and muscle first, and hair production is among the first things throttled back. This is one of the most common causes of unexplained shedding and stalled growth in women, and one of the least investigated.
Iron
Low ferritin (stored iron) is strongly associated with hair shedding in women, and you can be low enough to affect your hair while still testing "normal" on a standard haemoglobin check. The NIH Office of Dietary Supplements documents iron deficiency as widespread in women of reproductive age. Ask specifically for a ferritin test, not just a general blood count.
Protein
Hair is made almost entirely of keratin, a protein. Chronically low protein intake, common with restrictive dieting, reduces the raw material available for hair production.
Vitamin D
Deficiency is extremely common, especially in people with darker skin living at higher latitudes, and especially in winter. NIH guidance on vitamin D notes that melanin reduces the skin's vitamin D synthesis from sunlight, which puts Black women in northern climates at meaningfully higher risk.
How to tell if this is you: shedding spread evenly across the whole head rather than in patches, hair that feels finer overall, plus non-hair symptoms, fatigue, brittle nails, feeling cold, low mood. Especially likely if you have been dieting, are vegetarian or vegan without careful planning, have heavy periods, or gave birth in the last year.
The fix: a blood test, then targeted correction. Do not blind-supplement, some nutrients cause problems in excess, and supplementing for a deficiency you do not have wastes money and time you could spend fixing the real cause.
5. Medical and hormonal causes
Several medical conditions affect hair growth directly, and no product routine can compensate for an untreated underlying condition.
-
Thyroid disorders. Both underactive and overactive thyroid cause hair thinning and shedding. NIH guidance on hypothyroidism lists hair changes among the recognised symptoms. A simple blood test checks it.
-
PCOS and hormonal imbalance. Elevated androgens can drive pattern thinning at the crown and part. Often accompanied by irregular cycles, acne, or unwanted facial hair.
-
Telogen effluvium. Diffuse shedding triggered by illness, surgery, childbirth, major stress, or rapid weight loss, typically appearing two to three months after the trigger, which is why people rarely connect the two. Research on PubMed shows it usually resolves on its own once the trigger passes.
-
Medications. Some antidepressants, blood pressure medications, hormonal contraceptives, and others list hair changes as side effects. If your shedding started within a few months of a new prescription, that is worth raising with your prescriber, do not stop a medication on your own.
-
Alopecia. Autoimmune (alopecia areata), scarring (CCCA), genetic (androgenetic), and mechanical (traction) hair loss all have specific presentations and specific treatments. The guide to the types of alopecia covers how to recognise each, and the treatment options guide covers what can be done.
When to see a doctor rather than buy a product. Sudden or heavy shedding, visible thinning or a widening part, bald patches, scalp tenderness or pain, or shedding alongside fatigue, weight changes, or cycle changes, these warrant a medical appointment, not another jar. Early intervention dramatically improves outcomes for nearly every medical cause of hair loss.
6. Chronic tension from styling
Tight braids, tight ponytails, weaves and wigs installed under tension, and repeated pulling at the hairline cause traction alopecia. Per AAD guidance on hairstyle-related hair loss, it is fully preventable and caught early reversible, but long-standing traction permanently destroys the follicle.
How to tell if this is you: thinning concentrated at the hairline, temples, or wherever tension is applied. Small bumps around the hairline after installing a style. Soreness or headache after braiding. Short, fine, sparse regrowth at the edges.
The fix, and it is not subtle: stop the tight styles. Immediately. No product reverses ongoing tension damage while the tension continues. If a style hurts to install, it is damaging your follicles.
7. You are measuring it wrong (the shrinkage illusion)
Sometimes the hair grew and you genuinely cannot see it. Tightly coiled hair can shrink to a quarter or less of its actual stretched length meaning you could gain three inches over six months and see almost no change in a mirror check on unstretched hair.
How to tell if this is you: your stretched length has changed but your shrunken length has not. Twist-outs reach further than they used to. Your hair takes longer to detangle and feels heavier, but "looks the same."
The fix is measurement discipline: take stretched-length photos in consistent lighting from the same angle at month one, month three, and month six. Never judge growth on shrunken hair in a mirror, and never do weekly length checks, you grow an eighth of an inch a week and cannot perceive it, so weekly checks generate discouragement and nothing else. The chebe results timeline guide covers how to measure honestly.
8. You have reached your terminal length
This one is real, under-discussed, and worth understanding before you spend another year fighting it.
Every hair follicle cycles through a growth phase (anagen), a transition, and a rest before shedding and starting over. The duration of your anagen phase is largely genetic, and it sets a ceiling on how long any individual hair can get before it naturally sheds. Research indexed on PubMed shows anagen duration varies substantially between individuals, from roughly two years to seven or more. Someone with a two-year anagen phase has a terminal length around twelve inches. Someone with a seven-year phase can reach past their waist. Same growth rate, very different ceilings.
How to tell if this is you: your hair is genuinely healthy, ends are thick and blunt rather than thin and split, very little breakage, good elasticity, and it simply stops getting longer at a consistent point. Individual hairs shed at full length with a white bulb attached rather than snapping mid-strand.
The honest fix: there is no product that extends your anagen phase. What you can do is make sure you are actually reaching your terminal length rather than a breakage ceiling far below it, which, for most people who think they have hit terminal length, is what is really happening. True terminal length has thick, healthy ends. A breakage ceiling has thin, damaged ones. If your ends are compromised, you have room to grow.
If breakage is your answer, this is the fix. For the majority of people whose length has stalled, the cause is breakage, and the fix is sealing moisture into the strand so it bends instead of snapping. The Omez Chebe Hair Butter, authentic Chadian chebe with raw shea butter, avocado oil, castor oil, and rosemary oil, is built for exactly that job. Formulated for 4C and coily hair. But if your answer above was nutritional, medical, or hormonal, please start with a doctor rather than a jar. No product substitutes for treating an underlying cause.
How to work out which one is yours
Run through this in order. It takes about ten minutes and will point you at the right answer far more reliably than guessing.
-
Look at your ends. Thin, see-through, split, or ragged compared to your roots? Breakage. Thick and blunt? Not breakage, keep going.
-
Check what is falling out. Short fragments with no bulb are breakage. Full-length hairs with a small white bulb are normal shedding, you lose 50 to 100 a day and that is healthy.
-
Look at your scalp in good light. Flaking, redness, tenderness, or a visibly widening part? Scalp or medical cause.
-
Check where the thinning is. Concentrated at the hairline and temples suggests tension. Diffuse across the whole head suggests nutritional, hormonal, or telogen effluvium. Patches suggest autoimmune. Crown suggests androgenetic or CCCA.
-
Review the last six months. New medication, illness, surgery, childbirth, major stress, significant weight change? Telogen effluvium is likely, and it usually resolves on its own.
-
Take a stretched-length photo. Compare with any older photo you have. If the stretched length has changed, you are growing and retaining, the problem is measurement, not growth.
-
Assess your routine honestly. Are you sealing moisture, protecting at night, avoiding dry detangling, clarifying monthly? If several of these are missing, fix the routine before concluding anything more complicated.
FAQ
Why is my hair not growing past a certain length?
Almost always breakage, your ends are snapping off at roughly the same rate your roots produce new growth, creating a ceiling. Occasionally it is genuine terminal length, but that comes with thick, healthy ends. Thin, damaged ends mean breakage, and breakage is fixable.
Can hair stop growing permanently?
Individual follicles can be permanently destroyed by scarring alopecia or long-standing traction, and those do not regrow. But hair generally does not just "stop growing" across the whole head without a specific medical cause. If it seems to have, that is a dermatologist question.
Does trimming make hair grow faster?
No! trimming does not affect growth rate at all. It removes split ends that would otherwise travel further up the strand and cost you more length than the trim did. Every eight to twelve weeks, taking off only the damage, is the sweet spot.
How long should I try a routine before deciding it is not working?
Twelve weeks minimum for a fair test, and three to six months before judging length specifically. Softness changes in two weeks, breakage in four to six, visible length in three to six months. The results timeline guide breaks this down month by month.
Do hair growth supplements work?
They work if you are deficient in what they contain, and do very little if you are not. This is why a blood test is a better first step than a supplement aisle, correcting a real iron or vitamin D deficiency can produce genuine change, while supplementing nutrients you already have enough of will not.
Is winter making my hair growth worse?
Winter does not slow your growth rate, but it does accelerate breakage, dry air, indoor heating, and friction from wool coats and hats all compound. Most people lose more length in winter than any other season. The winter hair care guide covers the seasonal adjustments.
The bottom line
Your hair is growing. Roughly six inches a year, whether you can see it or not. The question is only ever what happens to it between the follicle and the mirror.
For most people the answer is breakage, and that is genuinely fixable with moisture, sealing, and less manipulation. For some it is buildup or scalp health, also fixable. For a meaningful minority it is nutritional, hormonal, or medical, and those need a blood test and a doctor rather than another product. And for a few, the hair is doing exactly what it is genetically able to do.
Work out which one is yours before you spend another year and another shelf of products on the wrong problem. If it is breakage, the complete 4C hair care routine and the chebe butter application guide will get you started. If it is anything else, this article has hopefully pointed you somewhere more useful than a checkout page.
