Sea and sun: taking care of your hair during the summer
Written on July 20, 2025, by Pauline de Santarome
During the summer, our hair is put to the test. Whether it's wind or sun, natural elements that dry out and damage hair, or chlorine, which can also dry it out considerably, there are many possible causes of dry hair.
In this context, it is essential to be particularly vigilant about hair care during the summer months.
Discover our tips for taking care of your hair and keeping it healthy despite external aggressions.
What are the effects of sea water and sun on hair?
Seawater contains minerals such as salt, magnesium, and calcium, which can add volume and texture to hair, giving it a naturally wavy appearance. However, salt can also dry out the hair and scalp, making it more prone to breakage and dehydration.
Exposure to the sun can damage hair. Ultraviolet (UV) rays can break down keratin, a protein that makes up hair, making it weaker, more brittle, and more prone to split ends. In addition, the sun can also alter hair color, especially for dyed hair, lightening or bleaching it.
Which shampoo should you choose for summer?
For summer, it is recommended to choose a shampoo tailored to the specific needs of your hair. If you have dry hair damaged by the sun, look for a moisturizing and repairing shampoo. If you have oily hair, opt for a balancing shampoo that controls sebum production.
Also, make sure the shampoo contains sunscreen to protect your hair from UV rays. Don't forget to moisturize your hair thoroughly after each wash and use a leave-in conditioner for extra protection.
Here are a few criteria to consider when choosing your summer shampoo:
Protect hair from sun damage: Choose a shampoo that contains UV filters.
Intense hydration: Choose a moisturizing shampoo to compensate for dehydration.
Anti-frizz: Choose an anti-frizz shampoo to keep your hair smooth and manageable.
Deep cleansing: Choose a clarifying shampoo that removes buildup from hair products and residue.
Light formula: Choose light shampoos that won't weigh your hair down.
Color protection: If you have colored hair, choose a shampoo specially formulated to protect your color.
Choose natural ingredients: Opt for shampoos made with natural ingredients such as aloe vera, chamomile, or coconut oil.
Adapting to your hair type: Consider your hair type when choosing a shampoo that suits your specific needs.
By following these tips, you can choose a shampoo that protects, moisturizes, and keeps your hair healthy during the summer.
6 tips for taking care of your hair during the summer
Moisturize your hair
In summer, hair is exposed to the sun's UV rays, which dry it out and damage it. That's why it's essential to moisturize it with specific products. Be careful, however, as excessive moisturizing can lead to hydration fatigue, i.e., hair exhaustion.
To moisturize your hair, it's up to you to determine which products are best suited to your needs.
Hair masks
Moisturizing shampoos
Conditioners
Oils
You should also know that some natural remedies can be very effective. Here are a few examples:
Raw egg yolk whipped and applied for ten minutes
A small amount of shea butter on the ends
Coconut oil applied for twenty minutes, rinse thoroughly after application.
Protect your hair from the sun and chlorine ☀ 💧
Sunlight and chlorine are aggressors that have a considerable impact on hair in summer.
That's why it's essential to cover them every day: with a hat, cap, or even a light scarf. It's up to you to decide what you think is most practical and stylish!
In addition to covering your head, it is recommended that you use hair products specially designed to protect your hair from the sun and chlorine. Here are a few tips to help you protect your hair:
- Use a hair sunscreen,
- Rinse your hair before swimming.
- Use a protective conditioner,
- Avoid exposure to the sun during the hottest hours of the day.
- Deeply moisturize your hair.
By taking care of your hair and adopting good protective habits, you can enjoy summer to the fullest while keeping your hair healthy and beautiful.
Washing frequency 🛀
Contrary to what one might think, washing your hair too often tends to damage it.
When hair is dry, the sebaceous glands do not produce much sebum. However, washing hair too regularly affects the production of this substance and causes the hair to produce even less or even more, which can make the hair look greasy.
It is therefore advisable to avoid daily shampooing and to wash your hair every three days if possible.
Some shampoos are more suitable for dry hair: choose "low poo" shampoos, which contain fewer harsh ingredients and active agents. More natural than traditional shampoos, they are gentler on dry hair.
Do not blow dry your hair 💇
Be careful, blow-drying your hair too often can make it even drier. Hot air removes water from the hair fibers and dries out the scalp.
However, hair dryers should not be banned entirely. Certain precautions should be taken when using them: Avoid excessive heat: to find out what temperature is safe for your hair, simply hold your hand under the hot air stream. If the temperature is tolerable, you can use your hair dryer, but avoid using it for more than ten minutes.
Repair your hair with plant oils 🌿
Vegetable oils are an excellent ally for maintaining and rehydrating hair. Contrary to what one might think, oils do not make hair particularly greasy and naturally regulate sebum production.
Here are a few examples of oils that can be used without moderation.
- Castor oil: known for its effectiveness on dry and damaged hair. Be aware that its texture is quite oily, which can make it difficult to apply. We recommend mixing it with another vegetable oil for optimal results and easy application.
- Coconut oil: this is one of the best known and most popular natural vegetable oils. It solidifies at low temperatures, so it is advisable to heat it in the microwave to make it easier to apply.
- Argan oil: It should be applied to the entire length of the hair, paying particular attention to the ends. The results are generally very positive: hair regains strength and shine, and dry hair loses its dry and brittle appearance.
Hair supplements 🌱
For healthy hair, natural solutions make all the difference!
- Dietary supplements: Dietary supplements are an excellent way to support hair health. They provide the body with the nutrients it needs to produce strong, healthy hair. Santarome Bio's Keratin Sublimes Cheveux Force & Croissance tablets contain a combination of amino acids (L-cysteine, L-methionine), vitamins and minerals (B6, B8, zinc, and selenium), plants ( horsetail, rocket, blueberry ), and geranium essential oil, which naturally strengthens and boosts hair growth and vitality.
Rinse your hair after every swim.
An essential tip for protecting your hair and preventingit from drying out: rinse your hair after every swim.
Seawater contains salt and iodine, which are rich in highly alkaline pH levels.
For dry hair, regular contact with sea water is therefore not recommended.
Don't forget to rinse them thoroughly as soon as you get out of the water.
With a little care and well-chosen dietary supplements, you can enjoy the sea and sun without fear, as they will not have too harmful an effect on your hair.
