Penjelasan Ilmiah Soal Rambut Beruban R ambut beruban umumnya muncul saat seseorang memasuki usia lanjut.
Namun, kini banyak kita jumpai laki-laki maupun perempuan yang memiliki rambut beruban meski usianya tergolong muda. Kira-kira apa ya alasannya?
Disampaikan asisten profesor dermatologi di Icahn School of Medicine di Mount Sinai, Gary Goldenberg, rambut beruban muncul pada usia muda karena kurangnya pigmen melanin pada folikel rambut.
Pigmen melanin sendiri bertanggung jawab untuk menampilkan rambut hitam berkilau. Pada mereka yang lanjut usia, jumlahnya berkurang sehingga rambut putih mulai muncul.
Berkurangnya pigmen melanin pada usia muda diyakini Goldenberg terjadi karena faktor genetik.
"Jika ibu atau ayah Anda mengembangkan rambut beruban pada saat muda, kemungkinan Anda juga akan mengalaminya," katanya.
Namun, jika keluarga Anda tak memiliki riwayat beruban di usia muda, Goldenberg menduga bahwa Anda kekurangan vitamin B12 yang bertanggung jawab terhadap munculnya risiko rambut beruban hadir lebih awal.
Kebiasaan merokok dan gaya hidup tak sehat lainnya juga berperan dalam memicu rambut beruban.
"Ada kemungkinan juga bahwa radikal bebas yang meningkat dapat mengurangi oksigen sehingga memicu kerusakan folikel rambut dan menyebabkan rambut beruban secara prematur," tambah dia.
Dan tentu saja pastikan bahwa Anda terlindungi dari risiko stres. Goldenberg mengatakan bahwa kadar hormon kortisol penyebab stres yang tinggi dapat mengurangi kadar pigmen melanin sehingga memicu rambut beruban lebih awal.
"Mengurangi tingkat stres bisa membantu menjaga kesehatan rambut Anda," tambah dia. (Menshealth).
