Causes
People typically lose about 100 hairs a day. This usually doesn't cause noticeable thinning of scalp hair because new hair is growing in at the same time. Hair loss occurs when this cycle of hair growth and shedding is disrupted or when the hair follicle is destroyed and replaced with scar tissue.

Hair loss is typically related to one or more of the following factors:

Family history (heredity). The most common cause of hair loss is a hereditary condition called male-pattern baldness or female-pattern baldness. It usually occurs gradually with aging and in predictable patterns — a receding hairline and bald spots in men and thinning hair in women.
Hormonal changes and medical conditions. A variety of conditions can cause permanent or temporary hair loss, including hormonal changes due to pregnancy, childbirth, menopause and thyroid problems. Medical conditions include alopecia areata (al-o-PEE-she-uh ar-e-A-tuh), which causes patchy hair loss, scalp infections such as ringworm and a hair-pulling disorder called trichotillomania (trik-o-til-o-MAY-nee-uh).
Medications and supplements. Hair loss can be a side effect of certain drugs, such as those used for cancer, arthritis, depression, heart problems, gout and high blood pressure.
Radiation therapy to the head. The hair may not grow back the same as it was before.
A very stressful event. Many people experience a general thinning of hair several months after a physical or emotional shock. This type of hair loss is temporary.
Certain hairstyles and treatments. Excessive hairstyling or hairstyles that pull your hair tight, such as pigtails or cornrows, can cause a type of hair loss called traction alopecia. Hot oil hair treatments and permanents can cause inflammation of hair follicles that leads to hair loss. If scarring occurs, hair loss could be permanent.
Risk factors
A number of factors can increase your risk of hair loss, including:

Family history of balding, in either of your parent's families
Age
Significant weight loss
Certain medical conditions, such as diabetes and lupus
Stress

1.雄激素性脱发
为常染色体显性遗传,其遗传特征需在雄激素作用下才表现出来。
2.神经性脱发
精神压力过大时常常出现脱发增多。在精神压力的作用下，人体立毛肌收缩、头发直立，植物神经或中枢神经机能发生紊乱，毛囊毛乳头发生改变和营养不良，从而导致毛发生长功能抑制，毛发进入休止期而出现脱发。
3.内分泌脱发
毛发生长受多种内分泌激素的影响，所以当发生内分泌异常时多引起脱发疾病，如产后、更年期脱发。
4.营养性脱发
毛发是身体状况的外在表现，机体营养不良和新陈代谢异常可引起发质和发色的改变，严重营养不良甚至导致弥漫性脱发。
5.物理性脱发
常见的引起脱发的物理性因素包括机械性刺激和接触放射性物质。
6.化学性脱发
化学因素可以导致毛发颜色改变甚至脱发。
7.感染性脱发
各种病原体的感染是毛发疾病中一类重要因素，主要包括细菌、病毒、真菌、螺旋体、寄生虫等感染。
8.症状性脱发
某些系统性或局部疾病都可伴发脱发。
9.先天性脱发
发育缺陷所引起的头发完全缺失或稀疏，患者常见头发稀疏细小，或出生时头发正常，不久就脱落不再生，可分为孤立缺陷和其他畸形。
10.季节性脱发
一般夏季容易脱发，因为夏天温度高毛孔扩张导致脱发，秋冬之际不易脱发，因为这时期温度下降毛孔闭合。

用秃头证明自己智商高。。震惊
难道不是精神压力过大？

@h82258652 你这样直接返回数据当然可以，但是为什么能统一返回格式不统一？手机端强类型的话要多做一层判空，他们当然不会愿意，这个东西后端直接封装一下返回，又不是什么难事。
