Introduction
If you've ever stared at hair in your brush or on the shower floor and felt a wave of panic — you're not alone. Seeing hair come out is alarming. But before you spiral, it's important to know the difference between shedding and breakage, because they have completely different causes and completely different solutions.
What Is Hair Shedding?
Hair shedding is a normal, biological process. Every single hair on your head has a growth cycle that ends in shedding. On average, people shed between 50 to 100 hairs per day. Shedding hairs always have a small white or dark bulb at the root — that's the hair follicle. This means the hair completed its cycle and released naturally from the scalp.
What Is Hair Breakage?
Hair breakage is damage. It occurs when the hair shaft snaps somewhere along its length — not from the root. Broken hairs will not have a bulb at the end. Instead, they'll have a blunt, uneven, or frayed end. Breakage is caused by factors like heat damage, chemical overprocessing, excessive manipulation, dryness, and protein/moisture imbalance.
How to Tell Them Apart
Grab a few strands from your brush or shower drain and examine the ends. Bulb present = shed hair. No bulb, short piece of hair = breakage. If most of the hair you're losing is short pieces of varying lengths with no bulbs, you're experiencing breakage, not normal shedding. If you're seeing longer hairs with bulbs but in larger quantities than usual, you may be experiencing excessive shedding, which warrants attention.
What Causes Excessive Shedding?
Shedding can become excessive (more than 100 strands per day consistently) due to hormonal changes (postpartum hair loss is very common), nutritional deficiencies especially iron and biotin, high stress, illness or surgery, thyroid conditions, and certain medications. Excessive shedding often resolves once the underlying cause is addressed.
What Causes Breakage?
Breakage is almost always a hair care issue: too much heat, too much color, too much tension, not enough moisture, not enough protein, or rough handling. The good news is that most breakage is preventable and, in many cases, reversible with consistent care.
What to Do About Each
-
For shedding: Focus on overall health, diet, stress management, and scalp health. Consult a doctor if shedding is excessive or sudden.
-
For breakage: Audit your heat usage, reduce chemical processing, deep condition regularly, balance protein and moisture, and handle your hair more gently.
