Hair treatment: what are the harmful effects of the sun?
Sun exposure is often associated with the joy of holidays, time spent at the beach and by the pool, but behind these pleasures, its UV rays have harmful effects on our skin and hair health . To maintain your beauty and hair health , specific care is therefore essential, whether it's applying sunscreen oil, using a protective shampoo, or even simply wearing a hat. In short, simple measures can help you preserve the health of your hair fibers.
On this page, we will explore in detail these sun-related problems and offer you some tips and solutions to ensure the protection and hydration of your hair during your holidays.
The harmful effects of the sun on the skin (and therefore the scalp)
Sun exposure, while beneficial for vitamin D, can have harmful effects on the skin and, by extension, on the hair. But to understand the impact on your hair, it's essential to know what the sun can do to your skin .
The sun's UV rays are divided into UVA and UVB. UVA rays penetrate deep into the skin and can cause premature aging, diminishing the natural beauty of the face and body. UVB rays, on the other hand, are primarily responsible for sunburn. Excessive exposure can therefore increase the risk of skin cancer.
Skincare to combat these harmful effects encompasses a range of products such as sunscreens, protective oils, and moisturizing sprays . Effective protection against direct sun exposure, especially during beach holidays or by the pool where the sun's reflection is amplified by water and salt, is obviously crucial. Similarly, wearing a hat or using a parasol offers additional protection.
Generally speaking, keep in mind that skin health is closely linked to scalp health. Damaged skin can therefore affect hair health and lead to dry and brittle hair.
The harmful effects of the sun on hair
Hair, like skin, suffers the harmful effects of the sun, especially during prolonged exposure without adequate protection. The beauty of the hair can then be compromised by several factors.
To begin with, the sun's UVA rays can alter hair color , especially in hair that has been dyed or is lighter in color. They penetrate deep into the hair fiber and break down the color molecules.
UVB rays are also particularly damaging to hair. They degrade proteins, such as keratin, which are essential for hair health and strength. Excessive sun exposure can even reduce its protein content by up to 10%.
Repeated sun exposure, combined with sea salt and pool chlorine, also strips hair of its natural oils and moisture . Dry, brittle hair is often the result of these unsuitable conditions.
But that's not all, since the sun can also damage the cuticle, the outer layer of the hair, making the hair more porous and vulnerable to other environmental aggressors. In other words, your natural shine is diminished.
Finally, let's not forget that a sunburned scalp causes itching and flaking, similar to sunburn on the skin .
Protecting yourself against sun damage
Protecting and treating hair from sun damage is essential for maintaining its beauty and health, since, as we've seen, prolonged sun exposure can cause considerable damage. Fortunately, there are effective ways to protect and treat your hair.
On the one hand, using a protective spray containing sunscreens can reduce the effects of UVA and UVB rays on hair. These hair products form a barrier that helps maintain color, shine, and hydration. Combined with a hat, they offer effective protection against heat and the sun's rays.
Dry and damaged hair can also benefit from regular hydration . Hair masks made with natural oils restore moisture lost due to sun, salt, and chlorine exposure. Organic products are still recommended for a more natural approach to hair care.
Of course, using a shampoo and conditioner specifically designed for sun-exposed hair helps remove salt and chlorine residue and restore the scalp's natural balance. Products containing nourishing ingredients like coconut or argan oil are particularly effective for treating sun-damaged hair.
Naturally, adopting a hair care routine during the summer months can make a significant difference. Applying sunscreen to the scalp, using a heat protectant before blow-drying, and protecting yourself from direct sun exposure during the hottest hours are all measures that can preserve the health of your hair.
