In Caucasian men, hair thinning may begin at a relatively young age, with symptoms becoming more pronounced in the late 20s and 30s.<\/li>\n\n\n\n<li><strong>Asians<\/strong>: The incidence of <a href=\"https:\/\/www.hiro-clinic.or.jp\/aga\/\">AGA<\/a> is lower among Asians, including Japanese, than among Caucasians. In Japan, about 30% <strong>to 40% of<\/strong> men over age 50 experience symptoms of <a href=\"https:\/\/www.hiro-clinic.or.jp\/aga\/\">AGA<\/a>. The onset of the disease is often somewhat late, with thinning hair progressing into the 40s and 50s in many cases.<\/li>\n\n\n\n<li><strong>People of African descent<\/strong>: People of African descent tend to have an even lower incidence of <a href=\"https:\/\/www.hiro-clinic.or.jp\/aga\/\">AGA<\/a> than Caucasians and Asians, but a certain percentage still have <a href=\"https:\/\/www.hiro-clinic.or.jp\/aga\/\">AGA<\/a>.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">2. <strong>Why <a href=\"https:\/\/www.hiro-clinic.or.jp\/aga\/\">AGA<\/a> is more common in Westerners<\/strong><\/h3>\n\n\n\n<p><strong>Genetic factors and hormones<\/strong> (especially dihydrotestosterone: DHT) play a major role in the development of <a href=\"https:\/\/www.hiro-clinic.or.jp\/aga\/\">AGA<\/a>. Differences in incidence by race are thought to be related primarily to genetic factors.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Genetic Factors<\/strong>: Westerners, especially Caucasian men, have a higher percentage of genetic mutations associated with <a href=\"https:\/\/www.hiro-clinic.or.jp\/aga\/\">AGA<\/a>. This makes them more susceptible to the effects of hormones and the damage DHT can cause to hair follicles, which leads to hair thinning.<\/li>\n\n\n\n<li><strong>Hormonal effects<\/strong>: DHT, a hormone converted from testosterone, is the primary cause of <a href=\"https:\/\/www.hiro-clinic.or.jp\/aga\/\">AGA<\/a>; when DHT binds to hair follicles, they shrink and hair growth is inhibited. Westerners are considered genetically more susceptible to DHT.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">3. <strong>Differences in age of onset of <a href=\"https:\/\/www.hiro-clinic.or.jp\/aga\/\">AGA<\/a><\/strong><\/h3>\n\n\n\n<p>Westerners generally tend to develop <a href=\"https:\/\/www.hiro-clinic.or.jp\/aga\/\">AGA<\/a> at a <strong>younger age<\/strong>, often in their late 20s or 30s, with more than half of men experiencing <a href=\"https:\/\/www.hiro-clinic.or.jp\/aga\/\">AGA<\/a> by their 50s.On the other hand, Asians and people of African descent tend to have a later age of onset, with symptoms typically appearing in their 40s or later.<\/p>\n\n\n\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img decoding=\"async\" width=\"640\" height=\"478\" src=\"\/aga\/wp-content\/uploads\/2024\/09\/race-specific-aga-rates-2.webp\" alt=\"\u5730\u7403\u3068\u4eba\u3005\" class=\"wp-image-3495\" srcset=\"https:\/\/www.hiro-clinic.or.jp\/aga\/wp-content\/uploads\/2024\/09\/race-specific-aga-rates-2.webp 640w, https:\/\/www.hiro-clinic.or.jp\/aga\/wp-content\/uploads\/2024\/09\/race-specific-aga-rates-2-300x224.webp 300w, https:\/\/www.hiro-clinic.or.jp\/aga\/wp-content\/uploads\/2024\/09\/race-specific-aga-rates-2-485x362.webp 485w\" sizes=\"(max-width: 640px) 100vw, 640px\" \/><\/figure><\/div>\n\n\n<h3 class=\"wp-block-heading\">4. <strong>Diffusion of <a href=\"https:\/\/www.hiro-clinic.or.jp\/aga\/\">AGA<\/a> treatment<\/strong><\/h3>\n\n\n\n<p>Treatment for <a href=\"https:\/\/www.hiro-clinic.or.jp\/aga\/\">AGA<\/a> is widespread regardless of race or region. Treatments such as finasteride and minoxidil are effective not only for Westerners, but also for Asians and people of African descent, and are used to slow the progression of <a href=\"https:\/\/www.hiro-clinic.or.jp\/aga\/\">AGA<\/a>.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">5. <strong>Summary<\/strong><\/h3>\n\n\n\n<p>The <strong>prevalence of <a href=\"https:\/\/www.hiro-clinic.or.jp\/aga\/\">AGA<\/a> among Westerners (especially Caucasian men)<\/strong> is strongly related to genetic factors and hormonal influences. Westerners have a higher incidence of <a href=\"https:\/\/www.hiro-clinic.or.jp\/aga\/\">AGA<\/a> and are more likely to develop thinning hair at a relatively young age, but not only do they have a higher incidence of <a href=\"https:\/\/www.hiro-clinic.or.jp\/aga\/\">AGA<\/a> than Asians and people of African descent, but they also tend to progress more rapidly. All races share the same treatment for <a href=\"https:\/\/www.hiro-clinic.or.jp\/aga\/\">AGA<\/a>, and with proper care and treatment, the progression of thinning hair can be reduced.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>1.
