Hair after sea and sun: how to protect and restore it in Phuket

Hair turns dry and straw-like in Phuket because UV light, salt water, chlorinated pools and constant humidity work on it at the same time: the cuticle lifts and the hair loses the lipids that keep it smooth. A simple routine prevents most of the damage — fresh water and a leave-in conditioner before swimming, a hat in the midday sun, a rinse and conditioner after every swim — and a professional treatment helps when home care is no longer enough. At ERA in Bang Tao, Deep Hydration & Nutrition and Care For Curly Hair cost ฿1,000 each and take about 30 minutes.

Why hair feels like straw after the sea: four causes

• UV light. Strong tropical sun breaks down keratin and the hair’s natural pigment. Hair loses its shine, dark hair turns reddish, blonde turns brassy and dyed colour fades faster.
• Salt water. As sea water evaporates, the salt stays on the hair and draws moisture out of it. Add sand and wind, and the cuticle turns rough.
• Chlorine. Pool water strips away the natural oils that protect the hair. Light and bleached hair can also pick up a greenish tint from copper in pool water.
• Humidity. Hair absorbs moisture from the air and swells, then dries out in the sun or under air-conditioning. Repeated every day, this wears out the cuticle and causes frizz — especially in curly and coloured hair.

The result is the same in every case: a lifted cuticle. Hair feels rough, tangles easily, splits at the ends and stops reflecting light.

How to protect hair from sun and salt water: a daily routine

Before you swim

1. Wet your hair with fresh water. Hair that is already saturated absorbs less salt and chlorine.
2. Apply a leave-in conditioner or a few drops of hair oil to the lengths and ends.
3. Tie long hair in a loose braid or bun to reduce tangling. In the midday sun, wear a hat: sprays with UV filters help, but they do not replace shade.

After you swim

4. Rinse with fresh water as soon as you can — do not let salt dry on your hair in the sun.
5. Wash gently: a mild, sulphate-free shampoo, conditioner every time you shampoo, and a mask once or twice a week.
6. Detangle with a wide-tooth comb while the conditioner is still in, starting from the ends.
7. Dry in the shade or with cool air, and keep hot tools on a low setting.

Do you need to shampoo after every swim? Not necessarily. Rinse with fresh water after every swim, but shampoo once a day — or whenever sunscreen and oil build up — and always follow with conditioner. Over-washing dries hair out as much as salt does.

What to avoid on a beach holiday

• Letting salt water dry on your hair in direct sun.
• Using strong clarifying shampoos every day.
• Rubbing hair with a towel — press the water out instead.
• Tight elastics on wet hair: strands break where they are weakest.
• Brushing wet hair with a dense brush.
• Lightening your hair right before a beach week, or swimming the day after colouring: fresh colour needs 48–72 hours.

Blonde and coloured hair: extra rules

Does salt water ruin dyed hair? Not in one swim — but sun, salt and chlorine together make colour fade and turn brassy much faster.

• Use a colour-safe, sulphate-free shampoo. A purple shampoo once a week neutralises yellow tones; used more often, it can dry the hair.
• In the pool, always wet your hair and apply a leave-in first. For platinum blonde, a swim cap is the safest option.
• If you are planning colour in Phuket, tell the colourist how much sun, sea and pool time lies ahead: it affects the shade and the care plan.
• Can you colour hair after the sea? Usually yes, but very dry, porous hair takes colour unevenly, and a colourist may suggest a hydration treatment first.

At ERA, colourist-curators from Russia with experience in complex colour techniques joined the team in October 2026. Women’s colouring costs from ฿3,500; the final price depends on hair length and technique.

When to book a professional treatment

Home care is usually enough for a short trip. Book a salon treatment when:

• hair still feels rough after a week or two of conditioner and masks;
• it tangles every time you wash it;
• your colour has faded within days;
• curls have lost their definition and frizz whatever you apply.

Hair loss on holiday: what salon care can and cannot do

Many people notice more hair on the brush after a move or a long trip, and sun, sweat and chlorine add stress to the scalp. Salon rituals — including Kydra anti hair-loss care for men at ERA — are cosmetic care for the scalp and hair; they do not treat medical conditions. If hair loss is sudden, patchy or lasts more than a few weeks, see a dermatologist or trichologist.
