The thickness of the hair mainly depends on the number and health of the hair follicles, and the number of hair follicles is determined by congenital, and shaving heads will not increase the number of hair follicles. When the hair is shaved, the new stage of hair growth will make the short hair look thicker and harder, giving a "stronger" illusion. In fact, the growth of hair is not affected by shaving, and the thickness and density of hair are still the same as before. In addition, the denseness of the hair is also closely related to factors such as heredity, hormones, diet, and pressure. Shavering heads cannot change these internal factors. If you want to improve the amount of hair or hair quality, you can help grow your hair healthy through a healthy diet, regular work and rest, and reduce stress. In short, shaving heads will not really make hair stronger. This misunderstanding is only caused by visual short -term changes and is not supported by scientific basis.
头发的浓密程度主要取决于毛囊的数量和健康状况，而毛囊的数量是先天决定的，剃光头并不会增加毛囊数量。当头发剃光后，头发生长的新阶段会让短发看起来较粗较硬，给人一种“更浓密”的错觉。实际上，头发的生长过程并未受到剃光的影响，毛发的粗细和密度依然和剃光前一样。而且头发的浓密程度还与遗传、荷尔蒙水平、饮食、压力等因素密切相关，剃光头并不能改变这些内在因素。要想改善发量或发质，可以通过健康饮食、规律作息、减少压力等方式来帮助头发健康生长。总之，剃光头并不会真正让头发变得更浓密。这一误解只是由视觉上的短暂变化引起的，并没有科学依据来支持。
