Some people want smooth hair, others dream of natural curls. But why is that so? The answer lies primarily in our genes and the shape of the hair root.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Genes determine the hair structure<\/h2>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-04162196\">The most important factor for our hair structure is heredity. Which genes we receive from our parents determines whether our hair grows straight, wavy, or curly. Therefore, within a family, the hair often looks similar, even though there may be differences.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">The shape of the hair root makes the difference<\/h2>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-0de4a33c\">Not only the hair itself is crucial, but also the hair root, also called a hair follicle.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Round hair follicles usually produce smooth hair.<\/li>\n\n\n\n<li>Oval hair follicles often lead to wavy hair.<\/li>\n\n\n\n<li>Starkly oval or curved hair follicles lead to frizzy or curly hair.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">The more curved the hair follicle is, the tighter the hair curls.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Why do hair sometimes change color?<\/h2>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-59178df4\">Many people notice that their hair structure changes over the course of their lives. There are various reasons for this:<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Hormonal changes<\/h2>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-6fd61c48\">During puberty, pregnancy, or in the menopausal years, hormones can affect the hair structure. Some people suddenly get more waves or lose their natural curls.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Age<\/h2>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-5ba3dd56\">As we age, the hair follicles change. This can cause hair to become finer or slightly change its original structure.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Medications and diseases<\/h2>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-69a9cef1\">Certain medications or illnesses can also affect hair growth and hair structure. The changes are sometimes only temporary.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Can straight hair become curly?<\/h2>\n\n\n\n<figure class=\"wp-block-image size-full is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"113\" height=\"500\" src=\"https:\/\/www.haartick-extensions.de\/wp-content\/themes\/woodmart\/images\/lazy.svg\" data-src=\"https:\/\/www.haartick-extensions.de\/wp-content\/uploads\/2026\/09\/stark-gewellt-naturblond.jpg\" alt=\"Stark gewellte Echthaar-Str\u00e4hne in Naturblond\" class=\"wd-lazy-fade wp-image-25699\" style=\"aspect-ratio:0.22598958333333333;width:120px;height:auto\" srcset=\"\" data-srcset=\"https:\/\/www.haartick-extensions.de\/wp-content\/uploads\/2026\/09\/stark-gewellt-naturblond.jpg 113w, https:\/\/www.haartick-extensions.de\/wp-content\/uploads\/2026\/09\/stark-gewellt-naturblond-3x12.jpg 3w, https:\/\/www.haartick-extensions.de\/wp-content\/uploads\/2026\/09\/stark-gewellt-naturblond-68x300.jpg 68w\" sizes=\"auto, (max-width: 113px) 100vw, 113px\" \/><\/figure>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-ccbff8dd\">Yes, that is possible. Especially hormonal changes can cause hair to grow looser or more wavy than before. Conversely, strong curls can also become smoother over the years.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Why do curls react differently to care?<\/h2>\n\n\n\n<figure class=\"wp-block-image size-full is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"343\" height=\"688\" src=\"https:\/\/www.haartick-extensions.de\/wp-content\/themes\/woodmart\/images\/lazy.svg\" data-src=\"https:\/\/www.haartick-extensions.de\/wp-content\/uploads\/2026\/09\/Echosline-Curl-Fluid.jpg\" alt=\"Echosline Curl Fluid f\u00fcr Locken\" class=\"wd-lazy-fade wp-image-25700\" style=\"aspect-ratio:0.49854166666666666;width:248px;height:auto\" srcset=\"\" data-srcset=\"https:\/\/www.haartick-extensions.de\/wp-content\/uploads\/2026\/09\/Echosline-Curl-Fluid.jpg 343w, https:\/\/www.haartick-extensions.de\/wp-content\/uploads\/2026\/09\/Echosline-Curl-Fluid-150x300-1.jpg 150w, https:\/\/www.haartick-extensions.de\/wp-content\/uploads\/2026\/09\/Echosline-Curl-Fluid-6x12.jpg 6w\" sizes=\"auto, (max-width: 343px) 100vw, 343px\" \/><\/figure>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-0289d362\">Curly hair has a harder time transporting the natural oils from the scalp to the tips. Therefore, curls often feel drier than straight hair and usually require more moisture and care.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Can one permanently change the structure of one's hair?<\/h2>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-66503669\">Using a flat iron or curling iron, the hair structure can only be temporarily changed. Permanent changes are, for example, possible through chemical treatments such as a permanent wave or hair straightening. However,<br>Such treatments can be harmful to the hair and should therefore only be performed by professionals.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Conclusion<\/h2>\n\n\n\n<figure class=\"wp-block-image size-full is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"1126\" height=\"1000\" src=\"https:\/\/www.haartick-extensions.de\/wp-content\/themes\/woodmart\/images\/lazy.svg\" data-src=\"https:\/\/www.haartick-extensions.de\/wp-content\/uploads\/2026\/09\/IMG_5993_6002.jpg\" alt=\"Vorher-Nachher: glatte braune Haare und gewellte kupferrote Extensions\" class=\"wd-lazy-fade wp-image-25701\" style=\"aspect-ratio:1.1259895833333333;width:452px;height:auto\" srcset=\"\" data-srcset=\"https:\/\/www.haartick-extensions.de\/wp-content\/uploads\/2026\/09\/IMG_5993_6002.jpg 1126w, https:\/\/www.haartick-extensions.de\/wp-content\/uploads\/2026\/09\/IMG_5993_6002-338x300.jpg 338w, https:\/\/www.haartick-extensions.de\/wp-content\/uploads\/2026\/09\/IMG_5993_6002-599x532.jpg 599w, https:\/\/www.haartick-extensions.de\/wp-content\/uploads\/2026\/09\/IMG_5993_6002-768x682.jpg 768w, https:\/\/www.haartick-extensions.de\/wp-content\/uploads\/2026\/09\/IMG_5993_6002-13x12.jpg 13w, https:\/\/www.haartick-extensions.de\/wp-content\/uploads\/2026\/09\/IMG_5993_6002-150x133.jpg 150w\" sizes=\"auto, (max-width: 1126px) 100vw, 1126px\" \/><\/figure>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-627edb90\">Whether curly, wavy or straight \u2013 the hair structure is mainly determined by our genes and the shape of the hair follicles. Throughout life, hormones, age or certain diseases can change the hair. Each hair structure has its own characteristics, and with the right care, any hair type can look healthy and beautiful.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>","protected":false},"excerpt":{"rendered":"<p>Genes determine the hair structure.
