Since you want to hear my opinion so much, I'll make it simple.
First of all, Rooney's hair transplant has been destroyed by domestic hair transplant hospitals. In fact, most hospitals don't care about Xiaopang's effect, but are willing to use Xiaopang's hair transplant as a gimmick and then use various tricks.
Many people may be attracted by the summary of Zhihu Daily, and Zhihu is quite good at playing the title party.
1. Why do some people say that Rooney is bald and dense for a while?
This is because there will be a shedding period after hair transplantation, which is a normal phenomenon after hair transplantation. That is to say, in the next 1-4 months after hair transplantation, the planted hair will not grow for the time being. At this time, some people will think that it is surgery, but it is not, but the nature and growth law of the hair follicle itself. Generally, after half a year (5-6 months) of hair transplantation, it will enter a large number of growth stages, so it is necessary to maintain a good attitude after hair transplantation and not to fall off. This is also a necessary stage after hair transplantation. Just go to our forum and have a look more. Don't tell me you can't find the forum website. If you are too lazy to look for it, I still suggest that you don't transplant your hair, because the probability of you falling into the pit is really great.
2. Why did Rooney do hair transplant twice?
Others will say that Rooney's hair transplant failed or the first time he did it was not very successful. Otherwise, why did he do it again? Want to know the truth, the bold text below, please fineness.
Hair transplantation has some limitations. In theory, a hair transplant operation can only make your hair density reach about 70% of normal people. If you are not bad at math, it should be easy to understand. For example, your forehead has lost light (initial hair follicle density is 0/cm2). If you want to achieve normal hair density (hair follicle density is about 70), it is possible to rely on 1 operation, and a single operation can only increase your hair follicle density by about 50%.
Because the scalp has a certain tension, it is impossible to plant hair follicles in a certain area without restriction in one operation. Once the density is too high, your scalp can't bear it, leading to the waste of hair follicles.
Interested students can test it with a needle and a piece of A4 paper to see how dense holes you can make. Once the distance between the two holes is too close and the connection is too tight, the hair follicle will be damaged and the effect will be meaningless. Therefore, if you want to achieve very good results (achieve normal hair density) from 0, you have to go through at least two operations. The first time, you will achieve 70% of the effect of normal people. After the scalp is fully recovered, on this basis, you will be encrypted for the second time. Seeing this, you should understand why Rooney did it twice.
Of course, for people with large hair loss and limited resources. Personally, it is not necessary to achieve normal hair density, as long as the hair follicle can cover the hair loss area, and the hair can cover the scalp when it grows out, and basically no hair loss image can be seen.
