What diseases are blondes prone to: research and observations by scientists reveal numerous potential aspects associated with blond hair and its impact on health.
This information was reported by Healthdigest, reports URA-Inform.
< p>Stanford University geneticist David Kingsley notes that the presence of blond hair is determined by a mutation in DNA, more specifically, a signaling gene that regulates the activity of other genes responsible for melanin synthesis.
The idea is that people with blonde hair have a mutation that reduces the production of melanin and, as a result, leads to a light shade of hair. Next, blonde hair is unfortunately associated with some hefty problems:
Hair loss and breakage
According to Unilever research scientist Diana Minar, people with naturally blonde hair experience increased natural hair loss. Moreover, such hair is more susceptible to ultraviolet rays from the sun. Prolonged sun exposure can cause dry, brittle hair and split ends.
Age-related macular degeneration (AMD)
A 2014 study published in the journal Investigative Ophthalmology & Visual Science indicates that people with blond hair who spent more than two hours outdoors during the hot summer months as teenagers are more at risk of developing AMD than those who spent less time in the sun during the summer. However, this risk was not observed in people with darker hair. Similar results were obtained in earlier studies published in the journal «Ophthalmology».
Increased risk of developing melanoma
A 2024 study published in the journal Gene found that skin melanoma appears to be more dangerous in people with red, blond, and light brown hair. While people with black hair do not have this risk. Similar findings are confirmed by earlier studies published in the International Journal of Cancer.
Thus, blonde hair, in addition to its aesthetic appeal, may be associated with various hefty risks and problems that require special attention and care. However, the above was the answer to the question of what diseases blondes are prone to.
