How important is Zinc? How can it affect Hair Loss? Dr. Yu's Explaination is Here I 锌到底有多重要？对脱发有
Zinc is one of the most important minerals in the human body. Although only a small amount is needed (only 100mg per day), it is vital to sustain function of our body. It can also facilitate our metabolism, immune function, and cell function.
Zinc is also essential to the reproductive and sexual function. The men’s semen contains zinc and the lack of zinc will drop the sexual desire, the quality of sperm, the level of testosterone, and weaken the immune system. For women, the lack of zinc will decrease the blood flow to the uterus, resulting in infertility, and cause the skin, nail, and hair become dull and lose elasticity.
Many years ago I read a study report. According to the report, hair loss patients’ soft and thin hair has less than normal zinc, but their blood contains normal level of zinc. Does this suggest zinc has something to do with hair loss?
The answer is yes. 90% of the zinc in the human body stay in the muscle and the bone and the rest 10% is in the blood. The zinc level in the blood cannot be lowered as it is essential to support the body’s function. Therefore, if the zinc in the blood is not enough, the muscle and bone will supply the blood zinc. Hair is not essential to support the body’s function, therefore the zinc hair will also be drawn to support the blood when there is not enough zinc in the blood. Once the zinc level in the hair drops, the hair will become thin and soft.
Meanwhile, excessive zinc level can also be harmful. It will cause human body to loose the equilibrium, affecting the level of cholesterol, and increase the chance of getting Cerebrovascular (the brain’s blood vessel) problems.
So, what is a best solution? Rebuilding a balanced system is the answer. If ones system is balanced, then he absorb enough Zinc from food, while extract excessive zinc. This is also TCM’s fundamental idea----the balancing of Yin and Yang. The zinc’s balancing depends first on the kidneys, then the liver. According to TCM theory, the liver is essential to the bone, the reproduction, urination, and defecation. Therefore, if the kidney is weakened, the bone and the reproduction will be affected. The result is the insufficient intake of zinc, and worsening of the overall health including the hair. Liver, on the other hand, is also important organ for the body to intake nutrients. Stress, depression, anxiety, insomnia, etc., would all affect the liver’s function, and cause the loss of balance, degrading the overall health.
In the traditional theory of TCM, the kidney and livers plays essential role in the growth of hair. In my practice, many hair loss patients also suffer from renal deficiency -- this may prove something.
Therefore, when we design the hair loss healing product, we consider the different types of hair loss of the different clients. The idea of balancing is practiced throughout the process by adding zinc to the formula, and adjusting the body’s function to stop hair loss and facilitate hair growth, restoring the health of hair. At the same time, our product can also help with overall health. Maybe that is why our products are effective.
锌（Zinc）是体内极重要的微量元素之一。虽然人体需要的锌极少，但是却是不可或缺的重要矿物质。我们每天锌的需要量在100mg左右，它能维持人体正常的生命功能，并且对新陈代谢，免疫功能和细胞功能都有调节作用。
同时，锌对维持男女的性功能也有很大作用。男性的精液里含有大量的锌，体内的锌不足会影响性欲，降低精子数量和品质，降低睾丸酮，削弱免疫力。女性缺锌，则会引起子宫的血流量下降，生育能力下降。同时，皮肤，头发，指甲的弹性，光泽等都会变差。
多年前我曾经看过一个研究报告。这份报告说，脱发者发质细软，稀疏的头发中，含锌量较正常人头发中的低，但是绝大多数脱发者的血液里，含锌量确是正常的。这是否说明锌与脱发有关系呢？
人体中90%的锌在肌肉和骨骼中，剩下10%在血液中维持生命功能。因此，血液中的锌是不能降低的，如果摄入的锌不够，肌肉、骨骼和其他次要部位就要减少锌的用量，把多余的锌供应给血液使用。头发属于最不影响生命功能的结构，因此血液中锌不够的时候，头发中的锌也会被抽取。因此，头发就会变得细软和稀疏。
此外，锌过多也不行。锌过多会导致人体状态失衡，如影响胆固醇水平，或增加脑血管病的机会等。
什么是最佳解决方案？就是平衡机制。这样既可以从食物中摄取足够的锌，又可以排出过多的锌。这种机制就是中医最基本的观念——“阴阳平衡”。锌的平衡机制主要取决于肾，其次是肝。中医认为：肾主骨，主生殖，主大小便。如果肾功能减弱就会影响骨骼健康，生殖功能不足，导致的结果就包括锌元素的吸收不平衡，从而影响头发健康和身体其他部分健康。 肝也是影响人体吸收营养物质的关键脏器。中医认为压力、抑郁、焦虑、失眠等均会影响肝功能，使身体失去平衡，进而影响身体各部分的健康。
从中医传统观念来讲，肝、肾都是影响头发最大的因素。我临床遇到过多个治疗脱发的病人，都有不同程度的肾功能减弱，或许能够说明一些问题。
因此，我们在设计脱发治疗产品时，根据不同病人的不同脱发类型，都采取平衡策略，给予微量锌元素，并着重平衡身体的功能达到停止掉发，促进头发生长，回复头发健康的目的。同时还能让身体更加康健。这也许就是我们的产品有效的原因。
