What PRP is
PRP 是什么
PRP stands for platelet-rich plasma. A small amount of your blood is drawn, spun in a centrifuge to separate its components, and the platelet-concentrated portion is injected into the scalp.
PRP 是富血小板血浆的缩写。抽取少量你自己的血液,用离心机分离成分,取出血小板浓缩的部分注射到头皮。
Platelets carry growth factors — signalling proteins the body uses in tissue repair. The theory is that concentrating them around hair follicles improves local blood supply and prolongs the growth phase of the hair cycle.
血小板携带生长因子——身体在组织修复时使用的信号蛋白。理论上,把它们浓缩到毛囊周围可以改善局部血供,并延长毛发周期中的生长期。
Because it comes from your own blood, there is no risk of an allergic reaction to a foreign substance. The risks that do exist relate to the procedure itself — sterility, technique and handling.
因为来自你自己的血液,不存在对外来物质过敏的风险。真正存在的风险来自操作本身——无菌、技术和处理流程。
The honest answer about who it helps
关于「对谁有用」的实话
This is where most of the disagreement comes from. PRP is not a single treatment with a single success rate — it is a treatment whose outcome depends almost entirely on what stage you start at.
分歧主要出在这里。PRP 不是一个有固定成功率的项目——它的结果几乎完全取决于你开始时处在哪个阶段。
- Early thinning, follicles still active — this is where PRP does its best work. Hair is getting finer, the part line is widening, but hair is still growing. There is something to support.
- 早期稀疏、毛囊仍活跃——这是 PRP 效果最好的阶段。头发变细、发缝变宽,但还在生长,有可以支持的对象。
- Moderate thinning — results are more variable. Some people see useful density improvement, others see stabilisation without much regrowth. Stabilisation is still a result worth having.
- 中度稀疏——效果差异较大。有人密度改善明显,有人只是稳住不再退,没有明显新生。能稳住其实也是有价值的结果。
- Established bald areas — PRP cannot help. Where follicles are no longer present, growth factors have nothing to act on.
- 已形成的光秃区域——PRP 帮不上忙。毛囊已经不存在的地方,生长因子没有作用对象。
A rough self-check: in good light, look at the thinning area closely. If you can see fine, short, wispy hairs, there are follicles still working and PRP has something to build on. If the skin looks completely smooth, that area is unlikely to respond.
一个粗略的自查:在明亮光线下仔细看稀疏区域。如果能看到细软的短毛,说明毛囊还在工作,PRP 有发挥空间。如果皮肤看起来完全光滑,那个区域大概不会有反应。
What the session involves
治疗过程
Blood is drawn, much like a standard blood test. It is spun in a centrifuge for several minutes to separate the plasma. The scalp is cleaned and numbed, and the plasma is injected across the thinning area in a grid of small injections. Start to finish, usually under an hour.
先抽血,跟普通验血差不多。放入离心机旋转数分钟分离血浆。头皮清洁并麻醉后,把血浆以网格状分布注射到稀疏区域。从头到尾通常不到一小时。
Afterwards the scalp is tender and may look slightly pink for a day. Hair can be washed the next day. Vigorous exercise and swimming are usually left for 48 hours.
结束后头皮会有压痛,可能泛红一天。第二天可以洗头。剧烈运动和游泳一般建议隔 48 小时。
Why the blood handling matters
为什么血液处理环节至关重要
This is the part of PRP that gets least attention and deserves the most. Drawing blood, handling it, and re-injecting it is not a cosmetic skill — it is a clinical one. Sterile technique, correct centrifuge parameters and safe sharps handling all sit outside standard beauty therapy training.
这是 PRP 中最少被讨论、却最值得关注的环节。抽血、处理、再注射不是美容技能,而是临床技能。无菌操作、正确的离心参数、锐器安全处理,这些都超出常规美容课程的范围。
Ask the question before you book. A clinic that handles blood properly will have no problem telling you exactly who does it and what they are qualified in.
预约前就问清楚。规范处理血液的诊所不会回避这个问题,会明确告诉你由谁操作、持有什么资质。
Setting expectations
建立合理预期
PRP is maintenance, not a cure. If the underlying cause of the hair loss is still active — and in pattern hair loss it usually is — stopping treatment means the process resumes. Anyone framing it as a permanent fix is overstating it.
PRP 属于维持性方案,不是根治。如果脱发的根本原因仍在持续——雄激素性脱发通常如此——停止治疗后过程会继续。把它说成一劳永逸的解决方案是夸大。
It also works best alongside the basics: iron and thyroid levels checked by your GP, adequate protein, managed stress. PRP into a body that is deficient in something fundamental will underperform.
它也需要基础条件配合:让全科医生查一下铁和甲状腺水平、蛋白质摄入充足、压力有所管理。身体本身缺乏某些基础要素时,PRP 的表现会打折扣。
