Survive Summer: prevent hair damage and maintain energy with smart strategies!

(5-minute read)

Introduction

Feeling like your hair is dry and your energy is depleted on hot days is more common than it seems. The sun, beach salt, and pool chlorine come into play... and there go your shine, strength, and even your mood. Based on scientific evidence, discover how to protect your hair from the sun, salt, and chlorine, and how to stay hydrated and full of energy on hot days with simple, effective, creative, and hassle-free tips.

Combined Summer Effects: Strong Sun, Saltwater, Chlorine, and Sweat

Ultraviolet (UVB and UVA) radiation severely damages hair: it breaks down proteins (keratin), oxidizes amino acids like cystine, methionine, and tryptophan, altering the hair's color, shine, and strength. Prolonged sun exposure leads to protein loss and changes in tone, especially in light-colored hair.

Sea salt strips natural oils, causing a porous, dry appearance and making hair more prone to breakage. Sand, on the other hand, causes micro-abrasions to the hair cuticle. In the pool, chlorine opens these cuticles and accelerates dehydration.

Finally, intense sweating and heat increase body and energy fluid loss, compromising physical and mental performance.

 Integrated Strategy: Preventing Hair Damage and Maintaining Energy

1. What you can (and should) do daily

• Protect your hair from the sun: hair offers some sun protection (up to about 50-80% UVA/UVB, depending on density), but this does not negate the use of wide-brimmed hats and accessories that cover the scalp directly.
• Avoid maximum sun exposure: between 11 am and 4 pm, UV impact is most aggressive; limit your time in the sun or seek shade whenever possible.
• Conscious diving: before entering the pool, wet your hair with fresh water to reduce chlorine absorption; after swimming, rinse immediately with cool water.

2. Protective and Repairing Hair Care

• Spray or leave-in with UV filters and antioxidants help shield hair from free radicals and reduce protein oxidation. Recommended product: René Furterer Solar Summer Protective Fluid KPF 50+ 100 ml
• Weekly intensive masks with natural extracts and/or extremely moisturizing ingredients that reduce degradation and preserve shine and color. Recommended product: Klorane Indian Fig Filler Mask for Shine and Hydration 250ml
• Nourishing oils on the ends, such as jojoba oil with vegetable keratin, seal cuticles and prevent friction that causes breakage. Recommended product: Apivita Keratin Repair Nourishing & Repairing Oil 100ml
• Wide-tooth comb and careful detangling, first with damp and then dry strands; reduces split ends caused by sand and salt.

3. Internal Hydration and Energy

Maintaining body hydration is crucial: a loss of just 2% of body weight due to fluid depletion reduces physical performance, concentration, and causes premature fatigue. Studies show that behaviors like "drinking only when thirsty" are already too late.

• Drink water regularly, about 200-250 ml every 20 minutes on hot days, especially if you are active.
• Include foods rich in water and electrolytes: watermelon (±92% water), cucumber (±96%), natural yogurt, and coconut water help replenish sodium, potassium, and magnesium.
• Avoid diuretic beverages like strong coffee or alcohol, which increase fluid loss. Moderation is suggested in these cases.

To prevent cardiovascular fatigue during prolonged exercise in the heat (a phenomenon known as cardiovascular drift), it is essential to replenish fluids and electrolytes during and after activity.

What is the relationship between hair protection and energy maintenance?

When you protect your hair from oxidative stress and hair dehydration, you are automatically taking care of your body: less protein loss, less internal effort, less feeling of tiredness. Good body hydration is reflected in hair strength and skin elasticity. By combining hair care (UV, leave-in, masks) with adequate hydration and nutrition, you strengthen both appearance and physical and mental performance.

Did you know:

• Sun exposure damages the superficial cuticle layer more (mainly UVB), but UVA penetrates deeper and degrades internal proteins like S100A3, causing structural fragility.
• A day of beach sun exposure can trigger oxidation similar to peroxide coloring, altering hair pigments and structure.
• People with less hair density (e.g., fine or thinning hair) receive up to 20-30% more UV radiation on the scalp compared to those with dense hair.

Makes you think, right? However, despite the necessary precautions, daily sun exposure – with adequate protection – brings numerous health benefits. Controlled sun exposure stimulates vitamin D production, essential for bone health, immunity, muscle function, and even in preventing chronic diseases like type 2 diabetes, cardiovascular diseases, and some types of cancer. Furthermore, sunlight regulates the circadian rhythm, improves mood, and reduces the risk of seasonal depression. Studies indicate that populations with greater controlled sun exposure have a lower incidence of autoimmune and metabolic diseases. In other words, as long as it's with sun protection, a hat, and exposure outside of peak intensity hours, the sun is a true ally for physical and mental well-being.
