Trichologist Twickenham: How to Read the Report You Were Given
A report from a trichologist Twickenham often runs to a page of terms nobody explained: anagen, telogen, diffuse, non-scarring, miniaturisation, calibre variation. Those words carry most of the meaning, and two of them decide whether the outlook is temporary or permanent. This guide translates each term into plain English, and separates the three different problems a report can be describing.

Key takeaways
- Anagen is growing, catagen is the short transition, telogen is resting. About 85 per cent of follicles are in anagen at any time.
- Non-scarring means the follicle is still there. Scarring means that patch will not produce hair again. This is the single most important word on the page.
- Diffuse means spread across the whole scalp. Patterned means concentrated at the parting, crown or temples.
- Miniaturisation and calibre variation describe follicles making finer hair, which is the signature of pattern hair loss.
- Telogen effluvium is temporary and eases over six to nine months. Pattern hair loss is gradual and continues.
- A report with no measurement and no review date has recorded nothing you can hold it to later.
What does a trichologist Twickenham actually write in a report?
A useful report records four things: what was seen on the scalp under magnification, which areas were examined, how the hair varies in thickness, and what is thought to be happening. Anything beyond that, including product suggestions, sits on top of those observations. The observations are what you can check again at a review, and they are the part worth reading closely.
Reports vary enormously in quality because trichology is not regulated the way medicine is. A trichologist Twickenham who names the areas examined, records a pattern reference and sets a review date has given you a document with a use. One that says "thinning noted, recommend the following products" has given you a receipt. Neither is medical advice, and neither should read as if it were.
The terms a trichologist Twickenham uses below are the ones that carry real information. Read them first, before the recommendations, because they determine whether the recommendations make any sense at all.
What do anagen, catagen and telogen mean on your report?
Anagen, catagen and telogen are the three stages every hair follicle moves through: anagen is active growth, catagen is a brief transition lasting one to two weeks, and telogen is the resting phase before a hair is released. DermNet records about 85 per cent of scalp follicles sitting in anagen and about 15 per cent in telogen at any one time.
Durations matter more than the names. The growing phase runs for years, described by DermNet as around four years on the scalp, while the resting phase lasts roughly three to four months. That asymmetry is why hair problems are slow to appear and slow to resolve, and why any review sooner than twelve weeks cannot show a cycle change.
When a report notes a raised telogen proportion, it is saying the ratio has shifted towards resting. DermNet explains that a shock to the system can push as many as 70 per cent of growing hairs into the resting phase, flipping the normal ratio and producing heavy, frightening shedding a couple of months later.
About 85 per cent growing, 15 per cent resting. A report describing a shift in that ratio is describing timing, not damage.
What is the difference between hair loss, hair shedding and hair breakage in a report?
Hair loss, hair shedding and hair breakage are three separate findings that a good report will never blur together: hair loss means follicles producing less hair or none at all, hair shedding means more hairs than usual completing the cycle and being released, and hair breakage means the fibre above the scalp snapping while the follicle underneath is unaffected.
| Report wording | What is happening | Where the problem sits | Typical outlook |
|---|---|---|---|
| Increased telogen hairs, diffuse shedding | More hairs released from the resting phase than usual | The hair cycle | Eases over six to nine months once the trigger passes |
| Calibre variation, miniaturisation, patterned thinning | Follicles making finer, shorter hairs | The follicle itself | Gradual and continues without intervention |
| Trichorrhexis, mid shaft breaks, weathered ends | The fibre snapping along its length | Above the scalp | Improves in weeks with less heat, tension and force |
| Non-scarring | Follicle structures still present | The follicle, but intact | New growth remains possible |
| Scarring, fibrosis, loss of follicular openings | Follicles replaced by fibrous tissue | The follicle, permanently | That area will not produce hair again |
The reason this matters commercially as well as medically is that the three findings have different answers. Masks and conditioners genuinely help breakage, because they work on the fibre. They do nothing for follicle density. Anyone whose report says calibre variation and who is sold a repair mask as the answer has been sold the right product for the wrong finding, a point the guide to telling breakage from real hair loss works through in detail.

What does telogen effluvium mean, and is it permanent?
Telogen effluvium means excessive shedding of resting hairs after a shock to the system, and DermNet classes it as a non-scarring diffuse hair loss with no evidence of inflammation. Not permanent is the short answer. The follicles are intact and the cycle has simply been disturbed, which is why the expected course is recovery rather than progression.
The timeline is well described. Increased hair fall is noticed two to four months after the triggering event, reaches a peak, then tapers back to normal over six to nine months in most cases. DermNet also notes it can affect up to half of the scalp hair, which explains why the shedding feels catastrophic even though the outlook is good.
There is a chronic form too. DermNet describes chronic telogen effluvium with no clear trigger presenting in otherwise healthy women aged 30 to 60, and notes it is often confused with pattern hair loss. A report that distinguishes the two has done something useful, because the expectations attached to each are completely different. The page on whether shedding will stop covers the waiting period.
The two words to look for first
Find "scarring" or "non-scarring" before you read anything else. Non-scarring keeps the door open. Scarring means that area is settled, and the conversation moves to covering and protecting what remains rather than to products.

What does androgenetic alopecia mean, and what does miniaturisation add?
Androgenetic alopecia is the formal name for pattern hair loss, the gradual patterned change most commonly seen at the parting and crown in women and at the temples and crown in men. Miniaturisation is the mechanism behind it: follicles produce progressively finer, shorter and lighter hairs instead of stopping abruptly.
DermNet explains that DHT, a hormone derived from testosterone, is believed to shorten the growing phase from its usual three to six years down to weeks or months, which is why affected hairs never reach full length or thickness. It also records how common the pattern is: up to half of male Caucasians experience some degree of hair loss by age 50 and possibly as many as 80 per cent by 70, with other population groups affected far less.
Calibre variation in a report is the visible fingerprint of that process. A scalp where hairs are all a similar thickness reads differently from one where fine, medium and coarse hairs sit side by side. Where on the scalp it appears is the other half of the picture, which the guide to hairline and crown changes takes further.

What do scarring and non-scarring mean, and why does it change the urgency?
Scarring means fibrous tissue has replaced the follicle, so that patch of scalp has permanently finished producing hair, while non-scarring means the follicle is still structurally present even if it is currently producing very little. Urgency follows directly from that distinction, because a scarring process closes a window and a non-scarring one usually rewards patience.
Traction is the everyday example of a process that crosses from one to the other. DermNet describes traction alopecia as caused by prolonged pulling on the hair, reversible in its early stages, and capable of becoming permanent once scarring sets in. That is why a report noting early traction at the hairline is genuinely time sensitive in a way that a report noting diffuse shedding is not. Related reading: our guide to diffuse thinning.
If your report uses the word scarring anywhere, that is the point to involve a GP rather than to buy anything. Scalp conditions that scar are medical, and the useful cosmetic conversation afterwards is about covering and protecting, not about density.
Which report words mean you should see a GP rather than buy a product?
Four groups of words point at your GP: anything about scarring or fibrosis, anything describing inflammation, scaling, pustules or weeping, any mention of defined patches of complete loss, and any suggestion that thyroid function or iron status should be checked. None of those are cosmetic findings and none are helped by a shampoo.
NHS blood tests cost nothing and cover the common general causes, including thyroid function and iron deficiency anaemia, both of which can show up as diffuse shedding. A trichologist Twickenham who writes that a GP should check those is giving you the cheapest useful next step, not passing you along.

Frequently asked questions
What does a trichologist Twickenham mean by anagen and telogen?
Anagen is the growing phase and telogen is the resting phase of the hair cycle. DermNet puts about 85 per cent of scalp follicles in anagen and about 15 per cent in telogen at any time, with anagen lasting around four years and the resting phase around four months. A report noting a raised telogen proportion is saying more hairs than usual are sitting in the resting phase.
Does non-scarring mean my hair can come back?
Non-scarring means the follicle structure is still present, which keeps the possibility of new growth open. Scarring means the follicle has been replaced by fibrous tissue and that area will not produce hair again. DermNet classes telogen effluvium as a non-scarring diffuse hair loss, which is why it is expected to settle rather than persist.
What does miniaturisation mean on a report?
Miniaturisation describes follicles producing progressively finer, shorter, lighter hairs rather than stopping outright. A report noting variation in hair calibre across the top of the scalp is describing that process. DermNet explains that DHT is believed to shorten the growing phase from a usual three to six years down to weeks or months, which is what produces the finer hair.
Is telogen effluvium the same as pattern hair loss?
No, and the distinction changes what happens next. Telogen effluvium is a temporary shift in the cycle following a shock, affecting the whole scalp diffusely and easing over six to nine months. Pattern hair loss is a gradual, patterned change in follicle output that continues without intervention. DermNet notes the two are often confused, and chronic shedding can sit alongside pattern hair loss.
What is a pull test and what does the result mean?
A pull test involves gently drawing a small bundle of hairs and counting how many come away. Several full length hairs with a pale bulb at one end point to active shedding from the cycle. Hairs that snap partway along point to a fibre problem rather than the follicle. The value is in repeating it at a review under the same conditions.
Should a trichologist Twickenham use the Ludwig or Norwood scale?
Those scales are simply patterns on a chart used to record how far a patterned change has progressed, one for female and one for male presentations. A scale reference in a report is useful because it gives the review something specific to compare against. A report with no pattern reference and no photograph has recorded nothing measurable.
What does a report mean if it says my scalp is inflamed?
Inflammation noted on a report is about the skin, not the hair cycle, and it belongs with your GP if it persists. A sore, scaly, weeping or spreading scalp should be looked at medically before any colour, bleach or strong product goes near it. Hair sitting on inflamed skin often improves once the skin does.
How much should I trust a report with no measurements in it?
Not much. Expect at minimum magnified examination of named areas, a photograph or parting measurement, a note of hair calibre variation, and a stated review date. The Institute of Trichologists runs a Level 5 course over two and a half years including 126 hours of hands-on clinical work, so this level of recording is well within the training.
What is the bottom line on trichologist Twickenham?
Read the observations in your report before you read any of the recommendations, because the observations are the only part you can check again at a review, and they are what determine whether the recommendations underneath them make any sense at all. Find the word scarring or non-scarring first, since non-scarring keeps new growth possible and scarring does not. Work out which of three findings you actually have: a shifted telogen proportion means timing and eases over six to nine months, calibre variation and miniaturisation mean follicle output and progress gradually, and mid shaft breaks mean the fibre and improve within weeks. A report from a trichologist Twickenham that names the areas examined, records a pattern reference or photograph and sets a review date is worth keeping. Any mention of scarring, inflammation, defined patches or blood tests is a signal to see your GP, where the tests cost nothing. If your question is about products or a routine rather than a medical one, you can talk to Gail Waterman, our co-founder, as an AI avatar on the Watermans homepage.
