Is bleaching your hair in the sun dangerous? – GOOD SHAPE

When it comes to having clear strands, the discoloration process can be seen as a necessary evil, with all the damage. And not just for the wires, but for your pocket as well, since getting it done in a beauty salon can be expensive.

For these and other reasons, many people choose to look for more “natural” ways to lighten their hair: through the sun. “The sun’s rays burn the melanin in the strands, as hair is made up of cells that do not regenerate, and consequently the strands are lighter in color” explains Maria Eduarda Pires, dermatologist.

But how is this possible? According to the dermatologist, sunbathing for one to four hours a day, especially in the summer, with the necessary care for capillary health, lightens the hair naturally through exposure to the sun’s rays. In addition, chamomile-based products or whitening products available on the market can facilitate the process.

THE RISKS OF LIGHTENING YOUR HAIR IN THE SUN

Although it seems harmless, bleaching your hair in the sun can have an impact on the health of your hair and scalp. “Excessive ultra violet rays can cause skin cancer, including on the scalp. When associated with chemical products, they can lead to contact dermatitis” warns José Roberto Fraga Filho, dermatologist.

Additionally, you may experience drier, more brittle strands as UV rays break down the protein compounds (known as keratin) in your hair. A lack of keratin can lead to brittle and weak hair.

WHAT ABOUT THE BENEFITS?

According to Maria Eduarda, the sun’s rays help in the growth of the wires and in the maintenance of capillary health, therefore, the professional always recommends the use of sunscreen for the wires as it reduces the action of UVA and UVB rays on the hair cuticles, thus, it keeps the strands protected and intact, leaving the hair more nourished, hydrated and strong.

IS IT WORSE THAN BLEACHING THE WIRES IN THE SALON?

The answer is no. This is because discoloration is much more aggressive, after all, when applied to the hair, the bleach penetrates the cuticle of the strands, removing all the pigment and after this process the hair loses capillary mass, that is, it becomes very fragile and dry.

However, it is not recommended to lighten hair in the sun. “The truth is that this discoloration process should always be done in environments protected from sunlight and accompanied by a professional, after all, the hair strands can be damaged” concludes Maria Eduarda.
