<h4>¡Hola, Steemians!. Un hecho obvio para todos es que cada día que pasa nos ponemos más viejos. Y con cada año que pasa, suceden cambios interesantes.</h4> ------------------- <center>Pero... ¿Por que nuestro cabello se pone gris cuando envejecemos? ¿Por que aparecen las canas?</center>  <h4><center>Averigüemos primero como adquiere el cabello cualquier tipo de color.</center></h4> El cabello, al igual que la piel, adquiere su color de un pigmento llamado melanina. >¿Sabías que la formación de la **melanina** ocurre incluso antes de que nazcas? >¿Sabías que todo tu cabello era **blanco** antes de que nacieras? >Bueno, ahora ya lo sabes. Los pigmentos oscuros se llaman **"eumelaninas"** y los claros se llaman **"feomelaninas"**, los cuales se mezclan para formar una amplia gama de colores de cabello.  <h4>Estos pigmentos están compuestos de células llamadas "melanocitos", las cuales están en la superficie de la piel. Los folículos de cabello crecen a través de las mismas mientras que los melanocitos inyectan melanina en las células que contienen keratina, la cual es la proteína de la que está hecho el cabello. </h4> Hay muchos factores, tanto externos como internos, que pueden cambiar la pigmentación de tu cabello: - Genética - Hormonas - Edad - El clima en donde vives - Toxinas - Exposición a sustancias químicas >Yo les preguntaría a tus padres y a tus abuelos cuando fue que les aparecieron las canas. Probablemente a esa edad a ti también te saldrán.  <h4>Para responder la pregunta inicial: tu cabello se pone gris a causa de un mantenimiento fallido por parte de las células de melanocitos. Puede que sea porque mueren o porque funcionan inadecuadamente. Mientras menos melanina tengas, más gris se pone tu cabello.</h4> >Cada folículo de cabello crece de forma individual su propia cantidad de melanina. Por esa razón, ciertas áreas del cabello se ponen grises en distintos momentos en relación a las otras. No hay una razón en concreto de por qué pasa esto. Estudios recientes afirmaron que los folículos de cabello producen pequeñas cantidades de peróxido de hidrógeno, lo que a larga puede conllevar a una pérdida del color.  <h3>Y tu, Steemian ¿que prefieres? ¿una larga y cómoda cabellera gris o simplemente nada de cabello para aparentar menos edad? Déjame saber en los comentarios.</h3> ------------------------------------ >Fuentes >http://www.loc.gov/rr/scitech/mysteries/grayhair.html https://www.patreon.com/LifeNogginStudios >http://www.livescience.com/14643-scientists-uncover-secrets-hair-turns-gray.html >Imágenes sacadas de www.pixabay.com
