                        Embora n\u00e3o cause preju\u00edzos f\u00edsicos graves, a alopecia\u00a0areata\u00a0pode ter grande\u00a0<\/span>impacto psicol\u00f3gico<\/span><\/b>:<\/span>\u00a0<\/span><\/p>\n

                              Perucas, len\u00e7os, maquiagem corretiva e acompanhamento psicol\u00f3gico podem ajudar a reduzir esse impacto.<\/span>\u00a0<\/span><\/p>\n

                              A alopecia\u00a0areata\u00a0pode estar associada a outras doen\u00e7as autoimunes, como:<\/span>\u00a0<\/span><\/p>\n
