Trichologists Hammersmith: What Can Wait, What Cannot
Some hair changes can wait three months. A few should not wait a week. Telling them apart is the whole skill.
The short answer. Urgency is decided by the scalp, not by the amount of hair. The trichologists Hammersmith residents search for are the right call for gradual thinning, breakage and routine review. A GP is the right call this week if you have a smooth bare patch, scalp pain or burning, sores, crusting or persistent scaling, or hair coming out in clumps over weeks. Scarring conditions destroy follicles permanently, so delay genuinely costs you.
Our hair growth conditioner
Condition Me® Hair Growth Conditioner, £13.95. Detangles and strengthens the hair fibre so lengths snap less on the brush and look thicker through the ends.
Key takeaways
- Scalp pain, sores, crusting or persistent scaling means a GP this week, not a hair consultation next month.
- A smooth, round, non-scaling bare patch is a medical matter with NHS pathways behind it.
- Scarring scalp conditions destroy follicles permanently, so early assessment changes the outcome in a way it does not for pattern thinning.
- A sudden all-over surge of shedding two to three months after illness, surgery or childbirth is usually self-limiting and settles within about six months.
- Gradual parting widening over years is real but rarely urgent, and it is what a trichology assessment is genuinely good for.
Which scalp symptoms should be seen this week rather than next month?
Five findings change the timetable: a smooth bare patch appearing over weeks, scalp pain or burning, sores or crusting, scaling that does not clear, and hair coming out in clumps rather than strands. Each of those points at the scalp as a medical problem, and each belongs with a GP before any private assessment. If you are comparing fees and qualifications, our guide to what a Bexley trichology appointment costs and who to see first goes through the options.
The reason is not caution for its own sake. Scarring scalp conditions, where inflammation replaces the follicle with fibrous tissue, cause permanent loss, and the window in which anything can be done is the early one. Redness at the hairline with a shiny, smooth band of skin where hair used to be is the pattern worth acting on quickly.
Pain is the symptom most often dismissed. Pattern thinning does not hurt. A scalp that burns, stings or feels tender to the touch is telling you something inflammatory is happening, and our page on scalp inflammation and what calms it covers the difference between soreness from tight styling and soreness that needs medical care.
What counts as urgent, and what genuinely does not?
Urgent means the scalp skin is abnormal or the loss is fast and localised. Not urgent means the hair is thinner but the scalp looks and feels normal. That single distinction sorts almost every case, and the table below is the version worth screenshotting before you phone anyone.
| What you are seeing | How soon | Who to see |
|---|---|---|
| Smooth round bare patch, skin normal, no scaling | This week | GP |
| Scalp pain, burning or tenderness | This week | GP |
| Sores, crusting, pus or spreading scaling | This week | GP |
| Shiny smooth band at the hairline where hair has gone | This week | GP, ask about dermatology referral |
| Scaling patches in a child, with broken-off hairs | This week | GP |
| Clumps over a few weeks with weight change, fatigue or heavy periods | Two weeks | GP, ask for blood tests |
| All-over surge starting 2 to 3 months after illness, surgery or childbirth | Watch for 3 months | GP if still climbing after 6 months |
| Parting slowly widening over a year or more, scalp normal | No urgency | Trichologist, for staging and routine review |
| Ends fraying, length stalled, short broken pieces at the parting | No urgency | Nobody; this is breakage, fix the handling |
Waiting is a legitimate decision for the bottom three rows. Paying 100 pounds to be told that a post-illness shedding phase will settle on its own is money spent on reassurance you could have had free, and the trichologists Hammersmith has to offer will usually tell you that themselves if you ask on the phone first.
How do you tell hair loss, hair shedding and hair breakage apart?
Hair loss means follicles producing progressively finer hair or none at all, which shows as scalp becoming visible through a widening parting. Hair shedding means whole hairs leaving a scalp whose growth cycle has been disturbed. Hair breakage means the fibre snapping mid-length while the follicle underneath is completely healthy.
Look at what comes out. Full-length hairs with a small pale bulb at the root end left the follicle naturally, which is shedding. Short fragments with no bulb at either end snapped, which is breakage. Hairs noticeably shorter and finer than the rest are the signature of follicular change, and that is the one a staging assessment is for.
None of the three, on its own, is an emergency. What makes something urgent is the state of the skin underneath, which is why the scalp check matters more than the hairbrush. Our guide to measuring terminal hair density at home will tell you whether density has genuinely changed or whether you are counting snapped fibre.
Why does a sudden surge of shedding usually not need urgency?
Disturbed-cycle shedding follows a predictable course: a trigger such as a high fever, surgery, childbirth, a crash diet or severe stress pushes a large number of follicles into their resting phase at once, and the hair falls two to three months later. The surge feels dramatic and is usually self-limiting, settling within about six months of the trigger passing.
That delay is the part people find hard to believe, because the hair falls long after they feel recovered. Working backwards three to four months from the day the shedding started usually finds the cause, and our guide to hair change after illness, surgery or a crash diet walks through that timeline in detail.
Two things do change the calculation. Shedding still climbing beyond six months deserves blood tests, and shedding alongside unexplained weight change, extreme fatigue or heavy periods deserves them sooner. Both are GP conversations rather than private ones.

What should you do about a smooth bare patch?
See a GP this week. A smooth, round, non-scaling bare patch, often the size of a coin and appearing over a few weeks, is the classic presentation of patchy autoimmune hair loss, and the British Association of Dermatologists publishes a public information leaflet on it. There are NHS pathways for this, and no cosmetic product has anything to offer. For hair that is snapping rather than shedding from the root, see the Chelsea guide to colour, extensions and breakage.
Do not buy anything for it. That is the single most useful sentence on this page, because the patchy-loss market is full of products aimed at people who are frightened and in a hurry. A shampoo cannot influence an immune process, and saying otherwise would be both wrong and illegal for us to claim.
If there is scaling in the patch
Scaling with broken-off hairs, particularly in a child, can indicate a fungal scalp infection, which is a medical matter requiring a GP. Do not share brushes, hats or pillows in the meantime, and do not try to manage it with cosmetics.
When is a trichologist the better choice than a GP?
The trichologists Hammersmith locals recommend are the better choice once the scalp is confirmed normal and the question is about pattern, staging, styling damage or routine. Half an hour on magnification, parting measurement, hair-type specific handling and a written plan is genuinely not what a ten-minute GP appointment is for, and the NHS does not usually cover pattern hair loss because it classes it as cosmetic.
Verification is yours to do, because trichologist is not a protected title in the UK and no statutory register exists. The Institute of Trichologists and The Trichological Society both publish searchable member listings; check the name on the register rather than the badge on the website. Then ask for the fee in writing and whether a written summary is included.
If a magnified scalp camera is part of the offer, understand what it does and does not show first. Our explainer on the trichogram and its limits covers why a single snapshot cannot tell you a direction of travel, and why your own dated photographs can.
What everyday care is safe while you are waiting?
Gentle handling, and nothing that stings, is what the trichologists Hammersmith readers see will advise anyway. Detangle from the ends upward with a wide-tooth comb, avoid brushing hair while it is soaking wet and heavy, lower the heat on dryers and straighteners, and loosen any style that pulls at the hairline all day. That removes breakage from the picture without touching the scalp question.
If the scalp is sore, broken or scaling, leave it alone and let a GP look at it. Active ingredients, exfoliating scrubs and scalp brushes on inflamed skin make the appointment harder, not easier. Cosmetics belong on a calm scalp.
Condition Me® Hair Growth Conditioner £13.95
£13.95. Cholesterol, shea butter, glycerin, silica and hydrolysed lupine protein, in a conditioner whose job is slip so the comb passes through rather than snapping fibres. A gentle everyday option for a calm scalp.
Sulphate free, so it cleans without stripping. Biotin, caffeine, rosemary and niacinamide support a healthy scalp environment and reduce breakage for fuller looking hair.
Tension is the habit worth changing today whatever the outcome. Styles worn tight daily cause a slow recession at the hairline that mimics pattern loss and has a completely different cause, and it is the most preventable hair change there is.
Frequently asked questions
Should I see a GP or a trichologist first?
See a GP first if the scalp itself is abnormal: bare patches, pain, sores, crusting or persistent scaling, or clumps over weeks. See one of the trichologists Hammersmith offers once the scalp is confirmed normal and the question is about pattern, staging or styling.
How quickly should a smooth bare patch be seen?
This week. A smooth, round, non-scaling patch appearing over a few weeks is the classic presentation of patchy autoimmune loss, which has NHS pathways behind it. Buying products for it wastes money, because cosmetics cannot influence an immune process.
Is scalp pain ever normal?
Tenderness after a very tight ponytail or braids is common and eases within a day. Pain, burning or stinging that persists is not normal and deserves a GP appointment, because inflammatory and scarring scalp conditions can cause permanent loss if left.
Can hair loss be an emergency?
Hair loss itself almost never is, but the scalp conditions that cause some of it can be time-sensitive. Scarring conditions replace the follicle with fibrous tissue permanently, so the early window is the one that matters.
My hair started falling out three months after surgery. Is that urgent?
Usually not. That delay is the signature of disturbed-cycle shedding, which typically starts two to three months after a trigger and settles within about six months. Ask for blood tests if it is still climbing beyond six months.
Do I need to stop using shampoo?
No, unless the scalp is broken, sore or scaling, in which case leave it alone and let a GP look. On a calm scalp, gentle cleansing and a conditioner with good slip reduce breakage and change nothing about the medical question.
What about scaling patches on my child's scalp?
Take a child with scaling patches and broken-off hairs to a GP this week, because a fungal scalp infection needs medical care. Avoid sharing brushes, hats and pillows meanwhile, and do not use adult hair products to manage it.
Is a widening parting urgent?
No. A parting widening slowly over a year or more with a normal-looking scalp is the classic gradual pattern, and there is no clock on it. It is exactly the case where a staging assessment and a routine review are worth paying for.
What is the bottom line on trichologists Hammersmith?
Let the scalp decide the timetable. The trichologists Hammersmith residents can reach are the right call for gradual thinning, breakage and routine review, and there is no rush on any of those. A GP is the right call this week for a smooth bare patch, scalp pain, sores, crusting, persistent scaling, scaling in a child, or clumps coming out over weeks, because scarring conditions cause permanent loss and the early window is the one that counts. When in doubt about which you have, the scalp skin, not the hairbrush, is the thing to look at.
If your scalp is calm and the real problem is snapped fibre rather than lost follicles, gentler handling and a hair growth conditioner with genuine slip will reduce breakage while you decide what else to do. If your scalp is sore or broken, see a GP first and leave the cosmetics until afterwards.
