Hair Shedding vs Hair Loss: How to Tell the Difference and Why It Matters

Finding hair on your pillow or in the shower drain doesn’t automatically mean you’re going bald. In most cases, it’s your hair doing exactly what it’s meant to do: shedding to make way for new growth. The real question is whether what you’re seeing is normal shedding or the early signs of genuine hair loss, and the two aren’t the same thing at all.

Getting this distinction right matters because the fixes are completely different. Normal shedding usually settles on its own, while true hair loss tends to progress if it’s left untreated. Here’s how to tell which one you’re dealing with.

What Is Hair Shedding?

Hair shedding is a normal, ongoing part of how your hair renews itself. Every strand on your head is cycling through growth and rest phases at any given time, and shedding is simply the tail end of that cycle.

The Normal Hair Growth Cycle (Anagen, Catagen, Telogen)

Each hair follicle moves through three phases:

Anagen (growth phase): Lasts two to seven years. Around 85 to 90% of your hair is in this phase at any time.
Catagen (transition phase): A short, two to three week phase where the follicle shrinks and growth stops.
Telogen (resting/shedding phase): Lasts around three months, after which the hair falls out and a new one begins growing in its place.

This cycle runs independently across thousands of follicles, which is why you don’t lose all your hair at once. It’s a constant, low-level turnover, not a single event.

How Many Hairs Is It Normal to Shed Per Day?

Losing between 50 and 100 hairs a day is considered normal. That might sound like a lot, but spread across roughly 100,000 follicles, it’s a small fraction of your total hair at any given time.

Shedding can look worse than it is, especially if you notice several days’ worth of hair at once (say, after washing your hair less frequently). What matters more than the daily number is whether the amount is increasing over time and whether your overall hair density is changing.

What Is Hair Loss?

Hair loss is a different process altogether. It happens when hair either isn’t regrowing after it falls out, or when the growth cycle itself is disrupted long-term, leading to visible thinning or bald patches.

Common Types of Hair Loss (Androgenetic Alopecia, Alopecia Areata, Telogen Effluvium)

Androgenetic alopecia (pattern hair loss): The most common form, driven by genetics and hormones. Shows up as a receding hairline or crown thinning in men, and diffuse thinning at the part line in women.
Alopecia areata: An autoimmune condition where the immune system attacks hair follicles, causing patchy hair loss.
Telogen effluvium: A temporary condition where a larger-than-usual number of hairs shift into the shedding phase at once, often triggered by stress, illness, or hormonal change. This one can actually resolve, which is why it sits somewhere between “shedding” and “loss.”

How Hair Loss Differs From Everyday Shedding

The key difference is regrowth. With normal shedding, every hair that falls out is replaced by a new one. With progressive hair loss, particularly androgenetic alopecia, follicles gradually shrink (a process called miniaturisation) and eventually stop producing visible hair altogether.

Hair Shedding vs Hair Loss: Key Differences

Timeline and Duration

Shedding is short-lived and tends to resolve within a few months, even when it’s triggered by something stressful. Hair loss, on the other hand, is typically gradual and ongoing, sometimes progressing over years if nothing is done about it.

Pattern (Diffuse vs Localised Thinning)

Shedding usually affects the whole scalp evenly. You lose more hair overall, but it’s spread out.
Hair loss often follows a pattern. Pattern hair loss shows up at the hairline, crown, or part line. Alopecia areata shows up as distinct round or oval patches.

Regrowth vs No Regrowth

This is the clearest test. Shed hair grows back on its own once the trigger resolves. Hair lost to conditions like androgenetic alopecia doesn’t grow back without intervention, because the follicles themselves are changing, not just resting.

How to Tell If You’re Shedding or Losing Hair

The Pull Test and Other At-Home Checks

A simple pull test can give you a rough idea of what’s going on:

Take a small section of unwashed hair (about 60 strands) between your fingers.
Gently pull from root to tip.
Count how many hairs come away.

Losing fewer than 5 to 6 hairs is generally within the normal range. Consistently pulling out more than that, especially over several tests across different parts of the scalp, can point to excessive shedding or active hair loss.

You can also track your hair over a few weeks with photos taken in the same lighting and position. This makes gradual density changes much easier to spot than they are day to day.

Signs That Point to Normal Shedding

Hair loss is spread evenly across the scalp
Overall hair volume feels roughly the same
There’s an obvious trigger (illness, stress, a new diet, recent birth)
It’s been going on for a few months, not years

Signs That Point to Hair Loss

A receding hairline, widening part, or thinning crown
Distinct bald patches
Visible scalp through the hair in certain areas
Thinning that’s been getting worse for six months or more
No obvious recent trigger

If you’re noticing the early signs of male pattern baldness or a widening part line, it’s worth paying closer attention rather than assuming it will pass.

Common Causes of Excessive Shedding

Stress and Telogen Effluvium

Significant physical or emotional stress can push a large number of follicles into the resting phase simultaneously. The shedding usually shows up two to three months after the stressful event, which can make the cause hard to pin down at first.

Diet, Nutrient Deficiencies, and Crash Dieting

Hair follicles are metabolically demanding and among the first things your body deprioritises when nutrition drops. Low iron, zinc, protein, or vitamin D are common culprits. Rapid weight loss or restrictive dieting is a well-known shedding trigger.

Postpartum Shedding

Pregnancy hormones keep more hairs than usual in the growth phase, so many women notice thicker hair while pregnant. After birth, hormone levels drop and those hairs shift into shedding all at once. This is completely normal and covered in more detail in our guide to postpartum hair loss.

Illness, Surgery, or Medication Changes

Fevers, infections, surgery, and starting or stopping certain medications can all trigger telogen effluvium. The shedding is usually temporary and resolves once the body recovers or adjusts.

Common Causes of Hair Loss

Genetics (Male and Female Pattern Baldness)

Androgenetic alopecia is largely inherited and linked to how hair follicles respond to hormones over time. It’s the most common cause of long-term hair thinning in both men and women, though the pattern differs between the sexes.

Hormonal Changes

Conditions like PCOS, thyroid disorders, and menopause can all disrupt hair growth cycles and contribute to thinning, particularly in women. Our article on why hair is thinning goes into more depth on female-specific causes.

Autoimmune and Medical Conditions

Alopecia areata, lupus, and some other autoimmune conditions can cause the immune system to attack hair follicles directly, leading to patchy or, in more severe cases, widespread hair loss.

Scalp Conditions

Chronic scalp inflammation, psoriasis, seborrheic dermatitis, and certain infections can all interfere with healthy follicle function and contribute to thinning if left untreated.

When to See a Doctor or Dermatologist

Warning Signs That Warrant a Professional Opinion

Book a consultation if you notice:

Thinning that’s clearly progressing over months, not settling
A specific pattern (receding hairline, widening part, patches)
Visible scalp or reduced density in specific areas
Scalp itching, redness, or scaling alongside hair loss
Hair loss alongside other symptoms (fatigue, weight changes, irregular cycles)

What to Expect at a Hair Loss Consultation

A proper consultation involves a health-practitioner-led review of your scalp, hair density, and medical history, and may include blood tests to rule out deficiencies or thyroid issues. This assessment is what determines whether you’re dealing with temporary shedding or a progressive condition, and it’s the only reliable way to know for certain.

Treatment and Prevention Options

Lifestyle and Diet Changes for Shedding

For shedding linked to diet or stress, the fix is usually addressing the underlying trigger:

Eating enough protein and iron-rich foods
Managing stress levels where possible
Avoiding crash diets
Being patient, since regrowth from telogen effluvium can take several months to become visible

Our list of best vitamins for hair growth is a good starting point if diet might be part of the picture.

Medical Treatments for Hair Loss

Ongoing or pattern-related hair loss usually needs a more targeted approach than diet alone. Treatment options can include topical and oral therapies, as well as procedures like PRP, which involves using a concentration of your own blood components to support follicle activity. Any medical or prescription-based treatment should only be considered following a consultation and clinical assessment with a qualified practitioner, who can advise on what’s appropriate for your specific pattern of loss. You can read more about the range of non-surgical regrowth options available.

Hair Care Tips to Minimise Damage

Regardless of the cause, gentler hair care habits help protect what you’ve got:

Avoid tight hairstyles that pull on the hairline
Limit heat styling and harsh chemical treatments
Use a wide-tooth comb on wet hair
Be gentle when towel-drying

The Bottom Line

Shedding 50 to 100 hairs a day, spread evenly across your scalp, with a clear trigger and a few months’ timeline, is almost always normal. Progressive thinning with a pattern, no obvious cause, and no sign of slowing down is worth having assessed properly.

If you’re not sure which category you fall into, that uncertainty itself is a good reason to get a professional opinion rather than guess. Left unaddressed, some causes of hair loss can continue to progress, so an early, accurate assessment gives you the most options.

Frequently Asked Questions

How can you tell if your hair is shedding or falling out?

Normal shedding is spread evenly across the scalp and usually has a clear trigger, like stress or illness, with hair regrowing within a few months. Hair loss tends to follow a pattern, such as a receding hairline or widening part, and doesn’t resolve on its own.

How long will hair shedding last?

Most shedding episodes, like telogen effluvium, resolve within three to six months once the underlying trigger (illness, stress, hormonal change) settles down. If it continues beyond six months or seems to be getting worse, it’s worth getting checked.

How do I know when I’m shedding?

You’ll typically notice more hair than usual in the shower, on your pillow, or in your brush, but your overall density stays fairly even and there’s no obvious bald patch or receding pattern forming. A simple pull test, losing fewer than 5 to 6 hairs per gentle pull, can help confirm it’s within a normal range.

What makes your hair fall out?

Common causes include genetics (pattern hair loss), hormonal changes, autoimmune conditions like alopecia areata, nutrient deficiencies, high stress, postpartum hormone shifts, illness, and certain medications. The right response depends on identifying which of these is actually driving the change, ideally with a professional assessment.
