A hat left on the coat rack, the spring breeze tousling the hair, and that sun starting to sting a little closer to the crown. As winter passes and we prepare for the gradual rise in temperatures, the skincare routine tends to renew itself right away, but hair is often relegated to the same old place: forgotten.
However, the ultraviolet radiation, combined with urban pollution, the wind, and the first outdoor excursions, directly impacts hair health long before the peak vacation season begins. Understanding how this assault works and how to prevent it is the first step to arriving at the warmer months with a strong and healthy fiber.
The Impact of Oxidative Stress on the Scalp and Hair Fiber
As the sun’s rays begin to strike with greater intensity, exposure to ultraviolet radiation increases, triggering what cosmetics call oxidative stress. This process speeds up premature aging not only of the skin but also of the hair structure.
“Hair, like the skin on the rest of the body, also suffers from the day-to-day external aggressions. Whether from cold, wind, sun, or pollution, these factors directly affect both the hair fiber and the scalp,” explains Ana Martínez, a specialist in hair care.
The UV radiation degrades essential proteins of the strand, such as keratin, causing a progressive loss of hydration, shine, and elasticity. If not protected in advance, the consequences become evident weeks later: dry, dull, rough strands with more frizz and a tendency to break easily.
In addition, the specialist emphasizes that the secret to dazzling hair lies in nourishing the origin from which each strand draws its sustenance. “Therefore, in addition to caring for and protecting the hair, we must also pay close attention to the scalp, sometimes with even greater vigilance, since any damage it suffers will be reflected directly in the health and appearance of the hair. A healthy scalp is the foundation for strong, shiny, and healthy hair,” Martínez states.
Which Hair Sunscreen to Choose According to Hair Type
The hair-care market offers different textures to incorporate sun protection without altering the visual finish. The key is to choose the right formula that meets the specific needs of each hair type without sacrificing volume or bounce.
- Thick, dry, or curly hair: It tolerates better formulas with oil-based textures or richer creams, which help to lock in moisture inside the fiber while blocking sun damage.
- Fine or oily hair: Requires protectors in spray format or ultralight mists to prevent strands from clumping or feeling heavy.
As for how to use it, consistency is key. The expert notes that the hair sunscreen should be applied from root to tip and reapplied throughout the day, especially if there is prolonged direct exposure or if we swim in a pool or the sea.
Key Ingredients and Simple Preventive Habits
When looking for a product on the beauty shelf, it is worthwhile to check the formulas. The actives most recommended by the specialist include UV filters, protective oils, vitamin E, antioxidants, panthenol, and keratin, ideal for protecting and repairing the fiber against environmental aggression.
Beyond the cosmetic product, incorporating small daily gestures makes a difference to prevent burns and extreme dryness:
- Add accessories: Wearing caps, hats, or scarves provides an indispensable physical shield during the sun’s most intense hours.
- Rinse after saltwater or chlorine: Rinsing the hair with fresh water after the pool or the sea helps remove chemical and saline residues that amplify sun damage.
- Move your hair part: Avoid keeping a very defined part in the same position for many hours, as this helps prevent painful sunburns on the scalp.
