How to Protect Your Hair This Summer: What Sun, Salt and Heat Actually Do

By Miriam, Founder of Miriam's Collection

Summer is one of our favourite times of year. But as much as we love long days, holidays and warm evenings, it is also one of the hardest seasons on your hair. 

UV exposure, salt water, chlorine and hot, dry air all take their toll, often gradually and without you noticing until the damage is already done. By the time September arrives, a lot of people are wondering why their hair feels so dry, brittle and dull compared to a few months ago. 

The good news is that protecting your hair through summer does not have to be complicated. A strong foundation going into the season makes all the difference. Here is exactly what summer does to your hair and how the right formula can help.

What Summer Actually Does to Your Hair

UV Exposure

Most people think about protecting their skin from the sun but forget their hair entirely. UV rays break down the proteins in the hair strand, weakening it from within and leaving it dry, brittle and prone to breakage. For colour treated hair, UV exposure accelerates fading significantly. For natural hair, prolonged sun exposure strips shine and elasticity in a way that can take months to repair.

Salt Water

Sea swimming is wonderful for the soul and genuinely difficult for your hair. Salt draws moisture out of the hair strand through osmosis, leaving it dehydrated and rough. It also roughens the cuticle, which is what causes that frizzy, straw-like texture so many people experience after a beach holiday. The longer salt water sits in your hair without being rinsed out, the more damage it does.

Chlorine

Chlorine is one of the most aggressive things your hair encounters. It strips the hair of its natural oils entirely, disrupts the scalp's oil balance and can cause significant dryness and breakage with repeated exposure. For curly hair in particular, chlorine is especially damaging because it causes significant loss of definition and moisture. Blonde and colour treated hair can even take on a green tint from copper oxidation in chlorinated water.

Hot, Dry Air and Increased Heat Styling

More occasions in summer often means more heat styling. Combined with hot, dry air that already dehydrates the hair strand, this creates the perfect conditions for heat damage to accumulate. Without proper protein support in your routine, the effects build up week by week and become increasingly difficult to repair.

How Our Formula Protects and Repairs

We did not choose our ingredients by accident. Every single one in our Rice Water Shampoo and Conditioner has a specific job to do, and several of them are particularly relevant in summer.

01. Rice Water (65%)

Rice water is the foundation of our formula and it makes up 65% of our shampoo. Not a trace amount and not a marketing claim. Real rice water is naturally rich in antioxidants, minerals like magnesium and zinc, and vitamins that repair the hair strand and restore natural shine. The antioxidants are particularly relevant in summer as they help counteract the oxidative stress that UV exposure causes on the hair. Think of it as the equivalent of antioxidants in skincare, but for your hair.

02. Hydrolyzed Keratin

Keratin is the protein your hair is made of. Heat, UV and chemical exposure all deplete it over time, which is why hair becomes brittle and prone to breakage through summer. Our hydrolyzed keratin fills in the gaps in the hair strand caused by this depletion, smoothing the cuticle and reducing the frizz that humidity and salt water create. It also makes the hair significantly more resilient to further damage.

03. Biotin

Biotin revitalises hair that has been damaged by heat and environmental stress. It works at the level of the hair strand to strengthen it from within and restore the shine that summer conditions strip away. If you have noticed your hair looking dull and lifeless by the end of summer, biotin is one of the most effective ingredients for bringing it back.

04. Ginger Root Oil

One of the most underrated ingredients in our formula. Ginger root oil is anti-inflammatory and acts as a sebum regulator, which is particularly important in summer when increased sweating and heat can throw your scalp's oil balance off completely. Whether your scalp runs oily or dry, ginger root helps bring it back to balance.

05. Amino Acid Cleansers

Our shampoo uses amino acid based cleansers rather than sulphates. This matters enormously in summer because your hair is already being stripped by sun, salt and chlorine. The last thing it needs is a shampoo that strips it further. Amino acid cleansers clean thoroughly without removing the moisture and natural oils your hair and scalp need to stay healthy through the season.

Miriam's Summer Tip: Use the Conditioner as a Pre-Swim Mask

This is one of my favourite summer hair tricks and it genuinely works. 

Before swimming in the sea or a pool, apply a generous amount of our conditioner to dry hair. Leave it for five to ten minutes and then get in the water. The conditioner creates a physical barrier that reduces how much salt water or chlorine can penetrate the hair strand. Because your hair can only absorb so much liquid at once, if it is already coated with conditioner it takes in far less of the damaging water.

The aloe in our conditioner forms a light film over the hair shaft, and the rice water and coconut oil help seal the cuticle beforehand so there is much less opportunity for chlorine to get in and strip your natural oils. It is a well known trick among regular swimmers and it is especially effective for curly and colour treated hair which is more porous and vulnerable.

Rinse out thoroughly after swimming and follow with a normal wash. You will notice a significant difference in how your hair feels.

The Bottom Line

The best time to protect your hair from summer damage is before it happens, not after. A shampoo and conditioner with the right ingredients does far more than clean your hair. It actively repairs, strengthens and shields it through every wash. If you have been thinking about switching your routine before summer properly hits, now is the perfect moment. Your hair will thank you by September.
