Trichologists Salford: Swimming, Chlorine and Dry Hair
Swimming a few times a week and hair feels like straw? Here is what the pool does, and what helps.
If you are searching for trichologists Salford because swimming has left your hair dry, tangly or tinged green, the pool is usually the cause, not your follicles. Chlorine and friction wear away the protective cuticle, and copper in pool water can stain light or bleached hair green. Wetting and conditioning hair before a swim, a snug cap and a thorough rinse afterwards help most. See a pharmacist or GP for a sore, rashy scalp, and a trichologist for shedding you cannot explain.
Key takeaways
- In a study of 67 Japanese national team swimmers, 61% had discoloured hair against none of 54 non-swimmers, and their golden hair had lost its cuticle completely.
- Green hair is usually copper rather than chlorine: in one French case the pool water carried 9.94 ppm of copper from algaecide, and the swimmer's green hair held 3,900 ppm.
- Bleached, permed or already weathered hair picks up copper more readily, which is why blondes and colour-treated hair go green first.
- Soak hair with clean water and conditioner before you swim, wear a snug cap, and rinse and condition straight after.
- A red, itchy or blistered scalp after swimming may be contact dermatitis: the NHS says speak to a pharmacist, and see a GP if it is persistent, recurrent or severe, before you contact any of the trichologists Salford searches bring up.
What does pool chlorine actually do to your hair?
Pool chlorine forms hypochlorous acid in the water, and that oxidising chemical, together with the friction of hair moving through water stroke after stroke, wears away the overlapping cuticle scales that protect each strand, so hair loses moisture, feels rough and straw-like, tangles easily and can fade or turn brassy with regular swimming.
The clearest evidence comes from a 2000 Journal of Dermatology study of 67 swimmers from the Japan National Swimming Team and 54 non-swimmers of the same age. Hair discolouration turned up in 61% of the swimmers and in none of the comparison group. Under scanning and transmission electron microscopes, the swimmers' golden, discoloured hairs had lost their cuticle entirely and carried chlorine inside the pigment granules of the cortex. The authors put the damage down mainly to friction with water, with hypochlorous acid then getting through to the cortex and oxidising the pigment.
Those were elite athletes training most days, so a couple of lane sessions a week is a far smaller dose. The effect still adds up over months, which is why regular swimmers notice the ends first: they are the oldest part of each hair.
Pool water is not a fixed quantity either. UK pools are run to standards set by PWTAG, the industry advisory group for pool water, whose guidance on common pool problems tells operators to check free chlorine and pH levels and, where algae appears, to raise free chlorine to 5mg/l overnight. So the chemistry your hair meets varies from pool to pool.
Sea swimming is a different problem, covered in our Portsmouth guide to sea, sun and salt water hair.
Why does blonde or bleached hair turn green in the pool?
Blonde or bleached hair turns green in the pool mainly because of copper rather than chlorine: copper dissolved in the water, often from algaecides or corroding pipework, binds to the weathered keratin of light, porous hair and shows up as a green tint that darker hair simply hides.
Doctors call it chlorotrichosis. A 1988 French study describes A 36-year-old blonde woman whose hair suddenly turned green after years of swimming. Her green hair contained 3,900 ppm of copper, and the pool water held 9.94 ppm because algaecide had been added without enough of the water being replaced. Once the water was renewed, the copper level fell to 107 ppb. The authors noted that repeated waving and bleaching make hair more likely to pick up copper, because the damage creates chemical sites in the keratin where copper binds.
Chlorine still plays a part, by roughening the cuticle so copper gets a better grip, but it is not the pigment. And the pool is not always the culprit: a 2014 US case report traced green hair, first blamed on the local pool, to copper that had leached from the plumbing of a rented house left empty for months. No recent swims? Check your tap water.
Green tint: what to try first
In a 2024 case report in Skin Appendage Disorders, a shampoo containing EDTA, an ingredient that binds metals, faded the green markedly within 8 weeks, and conditioner applied before swimming was the protective step. Look for EDTA on a clarifying or swimmer's shampoo. If several swimmers at one pool go green, tell the operator.
| What you notice | Most likely cause | What helps first |
|---|---|---|
| Dry, rough, straw-like ends | Cuticle worn by chlorine and friction | Conditioner before swimming, a cap, rinse and condition after |
| Green tint on light hair | Copper from pool water or household pipes | A clarifying shampoo with EDTA; tell the pool |
| Red, itchy or stinging scalp | Irritant or allergic contact dermatitis | Rinse well and speak to a pharmacist; GP if persistent, recurrent or severe |
| Far more whole hairs in the plughole | Shedding from a separate trigger | Think back around 3 months for a trigger; GP if heavy or sudden |
How do you protect your hair before and after swimming?
You protect your hair before and after swimming by soaking it with clean tap water and a layer of conditioner or light oil before you get in, wearing a snug cap, then rinsing straight away and conditioning the lengths, so the fibre takes up less pool water, less chlorine and less copper each session.
Hair soaked in clean water and coated in conditioner has less room, and less exposed surface, for pool water. The 2024 green-hair case report used exactly this logic, with conditioner applied before exposure as the protective step. Whether or not you end up seeing one of the trichologists Salford has, run this routine for a few weeks first:
- Shower before you swim. Most pools ask for it anyway, and PWTAG lists pre-swim hygiene among its actions for pools struggling with combined chlorine. Wet your hair right through while you are there.
- Coat the lengths. Smooth a little conditioner or a few drops of oil through the mid-lengths and ends.
- Wear a snug cap. Silicone caps sit closer to the head than fabric ones. No cap keeps hair fully dry, but a well-fitted one cuts how much water reaches it; tuck long hair in loosely, not in a tight bun.
- Rinse before you leave the poolside. Use the poolside shower before hair dries.
- Shampoo the scalp, condition the lengths. Lather at the roots in lukewarm water and condition from the mid-lengths down.
- Detangle last, and gently. Work a wide-tooth comb through conditioned hair from the ends upwards. Dragging a brush through wet knots is where most swimmer's breakage happens.
Camellia & Black Castor Hair & Body Oil
A multi-use oil with black castor oil, camellia oil and omega 3, 6 and 9. Smooth a few drops through damp lengths before your cap goes on for a light coating and extra slip.
A simple rhythm for swimming three times a week
Every swim: wet, condition, cap, rinse, then shampoo the scalp and condition the lengths. Once a week: a deep-conditioning mask on the mid-lengths and ends. Every few weeks, or at the first hint of green: a clarifying shampoo with EDTA, followed by conditioner.
An 8-in-1 deep conditioning mask with hydrolysed lupine protein, provitamin B5 and argan oil. Use it weekly on the lengths to help pool-weathered hair feel softer and reduce breakage.

Is it breakage, shedding or real hair loss after swimming?
Hair you lose after swimming is usually breakage, meaning short snapped pieces from tangled, weathered lengths, rather than shedding, which releases whole hairs with a tiny pale bulb at the root, or genuine hair loss, where follicles make finer, shorter hairs over time; the evidence points to pool water acting on the fibre rather than the follicle.
In the Japanese swimming team study, the swimmers' hair bulbs showed no difference from the non-swimmers' in a test of their pigment-making activity, even though the hair shafts themselves were badly weathered. Separate the three problems people lump together:
- Hair loss. The follicle makes finer, shorter hairs over time, or hair falls out in patches. Swimming is not a recognised cause.
- Hair shedding. The growth cycle releases more whole hairs than usual, often around 3 months after a trigger such as illness or stress.
- Hair breakage. The fibre snaps along its length. A 2024 case report described a volleyball player and recreational swimmer with years of chlorine exposure whose hair developed white knots along the shaft that fractured like two brushes pushed together, a pattern called trichorrhexis nodosa.
| Clue | Breakage | Shedding | Hair loss |
|---|---|---|---|
| What you find | Short pieces of different lengths | Full-length hairs | Finer, shorter hairs; a wider parting or patches |
| Root end | Blunt or frayed, no bulb | Small white or pale bulb | Often nothing obvious in the brush |
| Link to swimming | Common: weathered cuticle plus rough detangling | Not a known effect of pool water | Not a known effect of pool water |
| First step | Gentler routine, conditioner, wide-tooth comb | Look back for a trigger; GP if heavy | Speak to your GP |
The NHS says losing 50 to 100 hairs a day is normal. The British Association of Dermatologists notes that telogen effluvium, the medical name for heavy shedding, can start around 3 months after a trigger and is most noticeable after washing or brushing.
A conditioner with cholesterol, shea butter and hydrolysed lupine protein. Use it after every swim, and as a thin layer before, for slip that helps a comb glide through and reduces breakage.
Why does your scalp itch or sting after swimming?
Your scalp can itch or sting after swimming because chlorinated water can act as a skin irritant that strips away oils and natural moisturising factors, leaving the barrier dry and irritable, and in some people pool chemicals set off irritant or allergic contact dermatitis, with redness, dryness, cracking or blisters within hours or days.
DermNet explains that irritant contact dermatitis develops when chemical or physical agents damage the skin surface faster than it can repair, and that people with atopic dermatitis (eczema) are particularly susceptible. The NHS describes contact dermatitis as itchy, blistered, dry and cracked skin, red on lighter skin and dark brown, purple or grey on darker skin.
Rinse your scalp straight after every swim, wash with a gentle shampoo in lukewarm water and try not to scratch. If contact dermatitis is troubling you, the NHS suggests a pharmacist, who can recommend emollients. If you like to massage your scalp while you wash, our Oldham guide to scalp massage and thinning hair explains how to do it without causing breakage.
Speak to a pharmacist or your GP if
Your scalp is blistered, weeping, cracked or sore; the rash spreads to your face or body; symptoms are persistent, recurrent or severe, when the NHS says to see a GP; or you notice bald patches or sudden, heavy shedding. A GP can refer you to a dermatologist for further tests if the substance causing it cannot be identified.
When is a trichologist worth it for swimmer's hair?
A trichologist is worth it for swimmer's hair when a protective routine has had a couple of months to work and you still see shedding, thinning or breakage you cannot explain, or when you want an independent look at your scalp and hair shafts under magnification before buying more products.
The NHS advises seeing a GP to get an idea of what is causing hair loss before thinking about a commercial hair clinic, and that order makes sense here too. Most people searching trichologists Salford for straw-like pool hair need a routine change rather than an assessment. The people who gain most are those whose hair problem did not start with the pool, or did not settle when the routine changed.
- What a trichologist can do. Take a history of your swimming, products and colouring, examine scalp and hair shafts under magnification, where breakage patterns such as trichorrhexis nodosa show up, and track change over months.
- What they cannot do. Give you medicines. Most trichologists are not doctors, so anything needing medicines or blood tests goes back to your GP.
How do you check the trichologists Salford searches bring up?
The trichologists Salford searches bring up are private practitioners rather than NHS services, so check membership of a recognised body first: the Institute of Trichologists keeps a public Find a Trichologist register, and the Trichological Society is the other main UK professional body, so confirm which one before you pay.
The Institute of Trichologists says its UK register is accredited under the Accredited Registers programme of the Professional Standards Authority, an independent statutory body accountable to Parliament. For a swimmer's hair problem, ask three questions:
- Will you look at my hair shafts under magnification to tell breakage from shedding?
- If my scalp looks like contact dermatitis, will you send me back to a pharmacist or my GP?
- Are you recommending products you sell, and can I keep using my own?
We sell hair care, so weigh our view accordingly. Watermans hair care is vegan apart from Condition Me conditioner, made in the UK, with over 6.5 million bottles sold since 2012. They are cosmetic: they help hair look and feel healthier and reduce breakage, but they do not change pool chemistry or how your follicles behave.
What are the most frequently asked questions about swimming and hair?
Should I see one of the trichologists Salford searches list for chlorine-damaged hair?
Usually not at first. Dry, tangly or green-tinged pool hair is a hair-fibre problem that responds to a routine: wet and condition before swimming, wear a cap, then rinse and condition after. See a pharmacist or GP for a sore or rashy scalp, and a registered trichologist for shedding or thinning you cannot explain.
Does chlorine make your hair fall out?
Pool chlorine is not a recognised cause of hair loss. It weathers the hair shaft, so strands snap and tangle. In a study of Japanese national team swimmers, hair bulbs behaved normally despite badly weathered shafts. Heavy shedding of whole hairs, or thinning patches, point to another cause worth raising with your GP.
Why has my blonde hair gone green after swimming?
Copper, not chlorine, is the usual cause. Copper in pool water, from algaecides or pipework, binds to light, porous or bleached hair. One French case found 3,900 ppm of copper in a swimmer's green hair. A clarifying shampoo containing EDTA, which binds metals, and conditioner before swimming are the usual first steps.
Should I wet my hair before swimming?
Yes. Hair soaked with clean tap water, then coated with a thin layer of conditioner or oil, has less room and less exposed surface to take up pool water. Most pools ask swimmers to shower first anyway, and PWTAG counts pre-swim hygiene among the ways pools keep combined chlorine down.
How do I get chlorine out of my hair after swimming?
Rinse under the poolside shower before your hair dries, then shampoo gently at the scalp with lukewarm water and condition the mid-lengths and ends. Detangle with a wide-tooth comb from the ends up. Add a weekly mask and an occasional clarifying wash.
Why is my scalp itchy after swimming?
Chlorinated water can dry and irritate the scalp, and some people react to pool chemicals with contact dermatitis, which the NHS describes as itchy, dry, cracked or blistered skin. Rinse well after every swim and use a gentle shampoo. Speak to a pharmacist, and see a GP if symptoms are persistent, recurrent or severe.

What is the bottom line on trichologists Salford?
Straw-like, tangly or green-tinged hair after swimming is almost always a hair-fibre problem: chlorine and friction wear the cuticle, and copper stains light or bleached hair. Wet and condition before you swim, wear a snug cap, rinse and condition straight after, and use a mask weekly. A sore or rashy scalp needs a pharmacist or GP. Save the trichologists Salford searches bring up for shedding or thinning that is still unexplained once the routine has had time to work.
For the weekly reset that pool-weathered lengths need, a deep conditioning hair mask such as Masque Me adds softness and slip, with hydrolysed lupine protein, provitamin B5 and argan oil, to help rough ends feel smoother and reduce breakage when you comb.
