Breakage
Hair snapping along its length rather than leaving the scalp. It looks and feels like hair loss, and it is a different problem with different solutions.
01 What it is
Breakage is damage to the hair shaft. The hair fractures somewhere along its length, so what you find is short pieces without a root bulb rather than full-length hairs. Density at the scalp may be unchanged while the hair looks and feels much thinner.
Telling breakage from shedding is one of the most useful distinctions available, and it is easy to check: look at the ends. Shed hairs have a small pale bulb at one end. Broken hairs do not.
02 Recognition
What people usually notice
- Short pieces of hair on surfaces, without a bulb at either end.
- A halo of short hairs around the crown or hairline.
- Ends that feel rough, split, or 'crunchy'.
- Length that never seems to increase.
- A ponytail that is thin at the ends but not at the base.
- Hair that stretches then snaps when wet.
03 Contributors
What may contribute
Grouped by how well supported each one is. That distinction matters more than the list itself.
Well established
- Heat styling, particularly at high temperatures or on wet hair.
- Chemical processing: bleaching, permanent colour, relaxing, perming, especially in combination.
- Mechanical stress: tight styles, extensions, aggressive brushing, rough towel drying.
- Sustained tension on the hairline, which can eventually cause traction hair loss rather than simple breakage.
Commonly associated
- New regrowth after a shedding episode, which is shorter and finer and breaks more easily.
- Very hard water.
- Nutritional inadequacy affecting the quality of hair being produced.
- Some medications and health conditions that change hair texture and strength.
Debated or unsupported
- Protein treatments as a universal answer. Used on hair that does not need them, they make breakage worse.
- Trimming as a way to make hair grow, which it does not, though it does remove damaged ends.
- Most “repair” claims. Damage to the shaft cannot be reversed, only compensated for.
04 Uncertainty
What we don’t know
- How much everyday practice is genuinely responsible in a given person, versus how much the hair being produced has changed in quality.
Worth doing first
When to bring a doctor in
- If hair is breaking very close to the scalp across whole areas.
- If breakage began suddenly without a change in routine.
- If it is accompanied by scalp symptoms or by hair loss with visible scalp change.
- If there is loss along the hairline from tight styling. Traction hair loss can become permanent and is worth assessing early.
If any of this applies, see a doctor first. It’s the quickest way to an answer. Bring what they tell you back to me and we’ll work out what it means for you.
05 Consultation
What a consultation can explore
- Whether this is breakage, shedding, or both.
- The full picture of heat, chemistry, tension and handling.
- Whether the hair being produced has changed, which points somewhere different entirely.
- Water, environment and how hair is treated when wet.
- A realistic plan. Most breakage improves substantially with changes people can actually keep to.
Breakage is the most fixable thing on this list, which is why it is worth identifying correctly before treating it as hair loss.
What happens next
Book
Online, wherever you are. You’ll receive a questionnaire and a prep sheet, and I read both before we meet.
We look at it properly
History, assessment, findings, and time for the questions you came with.
You get it in writing
A summary you can act on, sit with, or hand to your doctor.
This page describes what people commonly experience. Reading it isn’t the same as having someone look at your situation properly, and it can’t tell you which of these you have. That’s what the consultation is for.
