婴儿大多都头发稀疏，这是什么原因？

阿的

大家好，本人抗秃至今已经快要4年了，雄性秃3级。昨天一个人躺在床上，忽然想到一个问题，不知道大家有没有发现，很多婴儿出生的时候头上毛发都非常细，还有些甚至是光头。如果我们能够找出，婴儿头发稀疏的原因，我们是不是也就能够找到我们脱发的原因了。不知道这个是不是脱发研究的突破口呢？大家有没有想过这个问题？

不一样的，婴儿的那个头发是还没有长好的，等正在长出永久性的头发，就不会在稀疏了

楼主，可以看看这个，国外介绍婴儿头发稀疏是如何形成的  
I'm sure someone can easily answer this, but it has been on my mind the past few days. When a baby is born a lot of them have very fine thin hair, then as they get older they start to grow hair and it becomes thicker. Well what is the baby missing when it is first born that causes the hair to be so thin? Whatever the baby is lacking could be the same that is causing mpb. I know its a pretty silly question but I was curious to see if there was any connection.

求翻译啊，鸟语早还给老师了

infants have at birth shed and are eventually replaced with terminal hairs. I do not think that the thin hairs get thicker.
婴儿的头发在出生时脱落，并最终被长出的永久性毛发所取代。我不认为其毛发是由薄变厚。
