The most effective way to stop telogen effluvium is to identify and resolve the trigger that caused it. This type of hair shedding is almost always reversible, but it requires patience: once the underlying cause is addressed, shedding typically slows over several weeks and new growth becomes visible within three to six months. There is no quick fix, but there are concrete steps you can take to speed your recovery and reduce the severity of the shedding.
Why the Shedding Is Happening
At any given time, about 5 to 15 percent of the hair on your scalp is in its resting phase. Each hair grows actively for roughly three years before transitioning into this resting stage, then falls out naturally to make room for a new strand. Telogen effluvium happens when a stress or disruption pushes a much larger percentage of follicles into the resting phase all at once. A few months later, all those resting hairs fall out together, and you notice dramatic thinning or clumps in the shower drain.
This delay between the trigger and the shedding is key to understanding what’s happening. The event that caused your hair loss likely occurred two to three months before you started noticing it. That means the trigger may already be over by the time the shedding begins, which is actually good news for recovery.
Find and Address Your Trigger
Stopping telogen effluvium starts with figuring out what set it off. Think back two to three months before the shedding started and look for one of these common triggers:
- Physical illness or high fever: Severe infections, COVID-19, and high fevers are among the most common causes.
- Major surgery or physical trauma: The body diverts resources away from hair growth during recovery.
- Childbirth: Estrogen levels rise during pregnancy, keeping hair in its growth phase longer than usual. After delivery, estrogen drops sharply, and all those extra hairs enter the resting phase at once. This typically starts about three months postpartum and can last up to six months.
- Psychological stress: Prolonged emotional stress, grief, or anxiety can trigger an episode.
- Thyroid problems: Both overactive and underactive thyroid function disrupt the hair cycle.
- Crash diets or poor nutrition: Diets that restrict protein or calories heavily are a well-documented trigger.
- Medications: Retinoids, blood thinners like heparin and warfarin, mood stabilizers, and certain antifungal medications can cause shedding. Hair loss from blood thinners typically appears three weeks to three months after starting the medication.
- Stopping birth control pills: The hormonal shift when discontinuing oral contraceptives can mimic the postpartum estrogen drop.
If your trigger was a one-time event like surgery, a fever, or childbirth, recovery is already underway. Your job is to support it. If the trigger is ongoing, like chronic stress, an untreated thyroid condition, or a nutritional deficiency, the shedding won’t fully stop until you resolve it.
Check Your Iron and Ferritin Levels
Low iron is one of the most treatable causes of telogen effluvium, and it’s frequently overlooked. In one study comparing women with telogen effluvium to those without hair loss, the average ferritin level (a measure of stored iron) in the hair-loss group was just 16.3 ng/mL, compared to 60.3 ng/mL in the control group. Women with ferritin levels at or below 30 ng/mL had 21 times the odds of developing telogen effluvium.
Dermatologists generally recommend treating iron deficiency when ferritin drops below 40 ng/mL, especially if you’re also experiencing fatigue, shortness of breath with activity, or pale skin. A simple blood test can check your levels. If they’re low, iron supplementation can make a meaningful difference in hair recovery, though it takes time to rebuild your stores.
Get Enough Protein
Hair is made almost entirely of a protein called keratin, and your body won’t prioritize hair production if it’s not getting enough protein from your diet. Fad diets, extreme calorie restriction, and plant-based diets that aren’t well-planned can all leave you short. The baseline recommendation is at least 46 grams of protein per day for women and 56 grams for men, though many dermatologists suggest aiming higher during recovery from hair loss.
Spreading your protein across meals matters more than hitting one large dose. Your body can only use so much at once for tissue repair. Eggs, fish, poultry, legumes, Greek yogurt, and tofu are all reliable sources. If your telogen effluvium was triggered by a restrictive diet, resuming adequate nutrition is the single most important step you can take.
Manage Ongoing Stress
Psychological stress is a legitimate physiological trigger for telogen effluvium, not just a vague contributing factor. The tricky part is that watching your hair fall out creates its own stress, which can extend the shedding cycle. Breaking this loop matters.
What works varies from person to person, but consistent sleep, regular physical activity, and structured stress-reduction practices like meditation or therapy all have documented effects on the body’s stress-hormone response. The goal isn’t to eliminate stress entirely. It’s to lower your baseline enough that your body stops interpreting daily life as a crisis and redirects resources back to nonessential functions like hair growth.
Talk to Your Doctor About Medications
If you suspect a medication is causing your shedding, don’t stop it on your own. Some drugs linked to telogen effluvium, like retinoids and blood thinners, serve critical medical purposes. Your doctor can help you weigh the risks of switching or adjusting your dose.
It’s worth noting that the evidence linking some commonly blamed medications to hair loss is weaker than you might expect. Beta-blockers and ACE inhibitors, for example, are frequently listed as causes, but the actual clinical evidence is limited to a handful of case reports. Retinoids and anticoagulants like heparin and warfarin have much stronger associations. A dermatologist can help sort out whether your medication is truly the culprit or whether something else is driving the shedding.
What About Minoxidil?
Topical minoxidil (the active ingredient in Rogaine) is sometimes recommended for telogen effluvium, though the evidence for it in this specific condition isn’t definitive. Its theoretical benefit is that it may help push resting follicles back into their active growth phase sooner. It’s generally well tolerated, and some dermatologists recommend it as a supportive measure while you wait for natural recovery.
If you try it, expect to use it consistently for at least three to four months before seeing results. Some people experience a brief increase in shedding when they first start, which can be alarming but is a recognized part of the process as older resting hairs are displaced by new growth.
What Recovery Actually Looks Like
Once the trigger is resolved, most people see shedding slow down over the following two to three months. New growth appears as short, fine hairs at the hairline and part line, sometimes sticking up at odd angles. These baby hairs are a reliable sign that your follicles are cycling back to normal.
Full recovery to your previous hair density takes longer, typically six to nine months after the shedding stops. Hair grows about half an inch per month, so even after new strands begin growing, it takes time for them to reach a length where they contribute to overall volume. During this waiting period, volumizing products, different parting styles, and gentle handling can help your hair look and feel fuller.
If your shedding continues beyond six months with no signs of slowing, it may have shifted into chronic telogen effluvium, which can persist for years in some cases. This is more common in women between 30 and 60 and often has no identifiable trigger. A dermatologist can perform a pull test, where a small section of hair is gently tugged, to assess whether active shedding is still occurring. Normally, two to five hairs come free. If more than 10 percent of the pulled hairs release, shedding is still active and further investigation is warranted.
Habits That Protect Your Hair During Recovery
While you can’t force follicles to grow faster, you can avoid making things worse. Heat styling, tight ponytails, braids, and chemical treatments all put mechanical stress on fragile, recovering hair. Switch to a wide-tooth comb, let your hair air-dry when possible, and use a silk or satin pillowcase to reduce friction overnight.
Washing your hair does not cause telogen effluvium or make it worse. The hairs that come out in the shower were already in the resting phase and ready to fall. Avoiding washing just delays when those hairs shed, making it look like more comes out at once when you finally do wash. Keeping a regular washing schedule gives you a more accurate picture of how much shedding is actually occurring.
