A practical pool-hair routine is simple: consider a swim cap or a small amount of oil/leave-in conditioner before swimming, rinse hair promptly afterward, then use a swimmers’ shampoo and conditioner. These are AAD’s dermatologist-authored swim-season suggestions, not a guarantee that any product blocks chlorine or prevents every kind of damage.
The American Academy of Dermatology explains that pool chlorine can affect hair lipids and proteins and may contribute to dryness, breakage or split ends. Its guidance below was last updated on 31 August 2021; no product, pool-water sample or hair strand was tested for this article.
Before, during and after the pool
| When | A practical step | Evidence boundary |
|---|---|---|
| Before swimming | Use a swim cap if comfortable. AAD also suggests applying oil or leave-in conditioner before entering the pool. | This is a precaution; it does not certify a product as chlorine-proof. |
| After leaving the water | Rinse hair promptly with fresh water. | Rinsing is a care step, not a measurement of chlorine removal. |
| After rinsing | AAD recommends a shampoo formulated for swimmers, followed by a deep conditioner. | Follow the chosen product’s label; no brand or formula was compared. |
| If hair is lightened or blonde | Use the same rinse-and-care steps; note any colour change and ask a colourist before corrective treatment. | AAD notes chlorine can interact with copper in water and contribute to a green tint; the cause of a specific colour change needs assessment. |
A checklist for a pool-day kit
- A comfortable swim cap, if you choose to wear one.
- Your usual oil or leave-in conditioner, used according to its own label; AAD presents these as optional pre-swim steps.
- Clean water for rinsing and a swimmers’ shampoo for after the swim.
- A conditioner suited to your hair and service history.
- A note of any recent lightening, colour service or unusual scalp reaction to discuss with a qualified professional.
AAD’s article also discusses sun exposure, which is a separate issue from pool chlorine. For a particular swimming pool, product, colour service or scalp concern, follow pool rules and product directions and consult a qualified stylist or clinician where appropriate. This checklist is a reading aid, not a salon treatment plan.
