Hair Breakage vs Hair Shedding: How to Tell the Difference and Address Each Correctly

The Single Fastest Way to Tell Them Apart

Pick up a fallen hair from your brush, pillow or shower floor. Examine the root end.

If you see a white or pale bulb at the root end: The hair shed from the follicle naturally. This is a telogen hair (shed at the end of the growth cycle). It is normal shedding.

If the root end has no bulb and the end looks ragged, tapered or snapped: The hair broke at a point along the shaft. This is breakage. The actual root is still in the follicle.

This test provides the answer within 5 seconds and requires no product or tool.

Normal Shedding: What It Is and When It Becomes Abnormal

Every hair follicle cycles through anagen (growth), catagen (transition) and telogen (resting and shedding). During telogen, the resting hair sits in the follicle until a new anagen hair pushes it out.

Normal shedding rate: 50 to 100 hairs per day. This sounds like a lot, but the scalp has 100,000 follicles; 10% to 15% in telogen at any given time produces this daily rate.

Counting your shed: If you are not detangling daily, shed hairs accumulate and release during the next combing session. Finding 200 to 300 hairs after 3 days without detangling is consistent with normal shedding that accumulated; it is not 200 to 300 hairs per day.

When shedding becomes abnormal:

• Consistent shedding of more than 100 bulbed hairs per day for more than 4 consecutive weeks
• Noticeably reduced density at the scalp when parting
• Visible scalp through the hair in areas where it was not visible before
• Diffuse thinning across the entire scalp rather than concentrated in one pattern area

Causes of increased shedding (telogen effluvium):

• Physical stressor 2 to 4 months ago (surgery, high fever, childbirth, major illness)
• Nutritional deficiency (iron, vitamin D, protein, zinc)
• Thyroid dysfunction
• Starting or stopping hormonal medications (oral contraceptives, hormone therapy)
• Extreme psychological stress sustained over months
• Significant weight loss (more than 6 to 7kg in a short period)

The timeline: Telogen effluvium shedding typically peaks 3 to 4 months after the triggering event and resolves naturally over the following 6 to 9 months as follicles return to anagen. Hair density returns to pre-shedding levels once the follicles have completed the return cycle.

Hair Breakage: Causes and Identification

Breakage differs from shedding in that the hair shaft snaps at a point along its length rather than releasing from the root.

Signs of breakage rather than shedding:

• Short pieces of hair (2 to 10cm) rather than full-length hairs
• Hair falling that has no root bulb
• Frizzier-looking hair at the surface (broken short sections standing up through the longer hair)
• Split ends visible at the tip of the hair strands
• Length that is not increasing despite the hair growing

The Causes of Breakage by Location

Where on the hair shaft breakage occurs tells you the cause.

Breakage at the ends (tips):

Dry, split or damaged ends are the most fragile. End breakage produces the shortest pieces of fallen hair. Causes: insufficient moisture at the ends, mechanical friction (cotton pillowcase, rough towel drying), heat damage at the tips from poorly controlled flat irons.

Breakage at the mid-length:

Mid-length breakage produces medium-length pieces. Causes: over-processing (chemical damage from bleach or relaxer applied repeatedly to the same section), elastic band damage (tight bands applied at the same point repeatedly), heat damage from diffuser or flat iron overexposure.

Breakage at the roots:

Root breakage produces the shortest pieces and creates the appearance of new growth that is actually broken sections. Causes: traction damage from tight styles, mechanical damage from aggressive detangling at the scalp, chemical overlap (chemical relaxer applied to already-processed hair).

Addressing Breakage: The Specific Fixes

For End Breakage

1. Trim the split ends (the split progresses upward if not removed; the sooner you trim, the less you lose)
2. Apply a sealing oil or cream to the ends after every wash
3. Switch to a silk or satin pillowcase
4. Avoid rubbing hair with a cotton towel; press dry instead
5. Apply a heat protectant before any heat styling at the ends

For Mid-Length Breakage from Protein Damage

1. Stop applying heat or chemical products to the affected section
2. Apply a bond-building or protein treatment (Olaplex, K18) every 2 weeks for 2 months
3. Increase moisturising deep conditioning alongside protein treatment (alternate each week)
4. Consider trimming the most damaged sections rather than treating indefinitely

For Root Breakage from Traction

1. Immediately loosen or remove the hairstyle causing the traction
2. Allow the scalp to rest without tight styles for 4 to 6 weeks
3. Apply a soothing scalp oil (jojoba, peppermint-infused carrier) to the affected hairline area
4. Vary the placement of ponytails, buns and hair ties; never return to the same tension point repeatedly

Addressing Shedding: The Specific Fixes

For Telogen Effluvium from a Physical Stressor

Address the trigger if it is still active. If the trigger has already passed (illness that resolved, childbirth 3 months ago), the shedding will resolve on its own schedule. Patience is the primary management strategy; no product accelerates follicle return to anagen.

For Shedding from Nutritional Deficiency

Order a blood test for: serum ferritin, thyroid function (TSH, T3, T4), vitamin D (25-OH-D), zinc and B12. Supplement only confirmed deficiencies under the correct guidance. Ferritin is the most commonly identified deficiency behind excess shedding; aim for ferritin above 70 ng/mL for optimal follicle support according to some trichological protocols.

For Ongoing Shedding Without an Identified Cause

Consult a dermatologist or trichologist. Persistent shedding beyond 6 months without an obvious trigger warrants professional assessment. Conditions including androgenetic alopecia, alopecia areata, thyroid disorders and scarring alopecia require specific diagnoses and targeted treatments that general hair care products do not address.
