How to protect your hair in the summer – the hairdresser's best tips for less frizz, dryness, and damage

Så skyddar du håret på sommaren – frisörens bästa tips för mindre friss, torrhet och slitage

Summer is often the period when hair is most exposed. Sun, UV radiation, saltwater, chlorine, heat, and drier air can quickly make hair feel:

  • drier
  • more frizzy
  • dull
  • more tangled
  • more brittle at the ends

Hair that felt soft and shiny at the beginning of summer suddenly feels rough, dry, and difficult to keep looking good after a few weeks of vacation. As a hairdresser, I often see that hair after summer is significantly more dehydrated than many realize, especially at the ends where the hair is already more delicate to begin with.

But with the right routine, it is absolutely possible to help your hair through the summer and maintain both shine, softness, and better hair health. Because we do have a little more time for that during vacation, don't we?!

Sun and UV radiation affect hair more than many realize

We are often very careful with SPF for our skin but forget that hair is also affected by the sun. The hair shaft is made of protein and surrounded by a protective layer that helps the hair retain moisture, strength, and shine. When hair is exposed to a lot of UV radiation, this protective surface is gradually affected, making the hair lose moisture more easily.

The result is often:

  • a drier feel
  • more frizz
  • less shine
  • hair that feels dull and "tired"

Colored hair is often affected even faster because UV radiation also breaks down the color pigments in the hair. This is why color often feels paler or less shiny after a lot of sun and swimming.

Does your hair look like this during the summer?

Why does hair get frizzy in the summer?

When hair loses a lot of moisture, the surface of the hair shaft becomes drier and rougher. This makes the hair react more quickly to:

  • heat
  • humidity
  • sun
  • drier air

This causes the hair to swell more easily, lose color, and become frizzy. That's why many people find their hair much harder to style during the summer, even if they use the same products as usual.

Is saltwater bad for hair?

Saltwater and chlorine affect the hair's moisture balance more than many realize. Hair works a bit like a sponge. When hair gets wet, it absorbs the water it comes into contact with, and when it then dries, a lot of moisture leaves the hair shaft again.

Saltwater and chlorine often make hair feel:

  • rougher
  • drier
  • more tangled
  • harder to detangle

When the surface of the hair shaft becomes drier, less light is reflected, causing the hair to lose its shine and feel frizzier. This is why many people experience that their hair feels completely different after a few days at the beach.

That's why you should always rinse your hair before swimming

One of my best tips as a hairdresser is actually very simple:
Rinse your hair with plain water before jumping into the pool or ocean.

Why?

If your hair is already saturated with plain water, it will have a harder time absorbing as much saltwater or chlorine. This helps your hair stay:

  • softer
  • less dry
  • less tangled
  • shinier after swimming
  • helps the color stay vibrant longer

Small things like this often make a much bigger difference than you might think over an entire summer.

How to protect your hair from the sun?

Just like skin, hair needs protection during the day. UV radiation causes hair to lose moisture more easily, which can make hair drier, frizzier, and less shiny over time. Therefore, I always recommend UV protection for hair during the summer.

UV protection helps protect hair from:

  • dehydration
  • frizz
  • fading from the sun
  • hair feeling rough and lifeless

And a tip many miss:
reapply UV protection throughout the day.

Especially after swimming or many hours in the sun. Then brush through your hair with Your Hair Brush to distribute the product evenly through the lengths and help your hair feel softer and less frizzy.

Moisture is often what hair needs most during the summer

Many believe that dry hair automatically needs more oil. But during the summer, it's often moisture that hair lacks most. During the summer, hair loses a lot of water from heat, sun, and swimming, which means hair needs help to retain moisture in the hair shaft.

That's why I always recommend:

  • hydrating hair care
  • leave-in products
  • UV protection for hair
  • products that help hair retain moisture during the day

Many hair types benefit more from light leave-ins during the summer instead of too many oils on top of an already dehydrated hair shaft.

That's why hair breaks more easily in the summer

A common sign that hair has become dehydrated during the summer is that the ends start to feel thinner, drier, or break more easily than usual. When hair loses a lot of moisture, the hair shaft becomes more sensitive and less elastic, which makes the hair break more easily during brushing, styling, and everyday wear and tear.

This is also why hair often feels more tangled in the summer. The drier the hair becomes, the more delicate the lengths become.

That's why the right hairbrush makes such a big difference in the summer

Many don't consider how much difference brushing itself makes to the hair's feel and quality over time. During the summer, hair often becomes drier and more sensitive, which means it breaks more easily when tangled or dehydrated.

Your Hair Brush helps to:

  • detangle hair gently
  • reduce frizz
  • help hair feel shinier
  • stimulate the scalp
  • distribute the hair's natural oils from the scalp to the ends

And that last point is so important.

The hair's natural oils actually act as a natural protector for the lengths. The problem is that the oils often stay near the scalp while the ends become drier and drier, especially during the summer.

When you brush your hair, you help distribute the oils through the hair, which helps the lengths feel:

  • softer
  • less dry
  • shinier
  • less frizzy

At the same time, the scalp is stimulated, which helps keep the scalp in better balance during the summer.
