脱发，讲清楚。
植发，说实话。Hair loss, explained properly.
Hair transplant, explained honestly.

这些名字说的都是“种植”这一步用的工具，不是提取方式。提取仍然是 FUE 或 FUT，见第四章。These names all refer to the implanting step, not to how follicles are taken out. Extraction is still FUE or FUT, as in chapter four.

• 宝石刀，两步法。先用宝石刀打出微孔，再用镊子把毛囊放进去。方向和密度容易控制，适合较大面积。Sapphire blade, two steps. Tiny slits are opened with the blade first, then each follicle is placed with forceps. Direction and density are easy to control, which suits larger areas.
• 种植笔或微针，即插即种。毛囊装进笔头，打孔和种植一步完成。创口更小，适合头顶加密和细部修补。Implanter pen or DHI, one step. The follicle is loaded into the pen, and opening and placing happen in one motion. Smaller wounds, which suits adding density on the crown and fine touch-ups.

工具没有绝对的好坏。发际线和大面积覆盖，两步法成熟可控；头顶加密和二次修补，种植笔的优势更明显。用哪一种，由医生按你的供区、头皮和目标决定。Neither is better in every case. For the hairline and wide coverage the two-step method is mature and controllable; for crown density and second passes the pen has the edge. The doctor chooses based on your donor area, scalp and goal.

在局部麻醉下进行。过程中多数人感到的是压力而不是疼痛；术后几天可能有紧绷和不适，由医生指导处理。It is done under local anaesthetic. Most people feel pressure rather than pain; the first days after can bring tightness and discomfort, which the doctor guides you through.

取决于方向、角度，和前排是否用单根毛囊。这就是分离和种植这两步重要的原因。It depends on direction, angle, and single-hair units at the front edge. That is why the separation and implanting steps matter.

核心看两件事：后脑供区的毛囊够不够，脱发是不是已经稳定。Two things decide it: whether the donor area at the back has enough follicles, and whether the loss has settled.

通常适合：雄激素性脱发（男性发际线后移、头顶稀疏，女性头顶弥漫变薄）而且供区充足；脱发已经放缓；外伤、烧伤或手术留下、已经稳定的疤痕；眉毛、胡须、鬓角的加密和塑形。Usually suits: pattern hair loss (a receding hairline or thinning crown in men, diffuse thinning on top in women) with a good donor area; loss that has slowed; stable scars from injury, burns or surgery; adding density or shape to eyebrows, beard or sideburns.

需要等，或不适合：Wait, or not suitable:

• 斑秃。免疫系统在攻击毛囊，移植过去的毛囊同样可能被攻击。先由皮肤科医生控制病情。Alopecia areata. The immune system is attacking follicles, and moved follicles can be attacked too. A dermatologist controls the condition first.
• 脱发正在快速进展。周围的原生发继续掉，移植区会变成一座“孤岛”。先由医生把进程稳住，再评估。Loss that is progressing fast. The hair around the grafts keeps going and leaves an island. A doctor stabilises it first, then assesses.
• 供区太薄。没有足够的“种子”可以移。A thin donor area. Not enough seed to move.
• 瘢痕体质。术后的疤痕可能比脱发本身更明显。A tendency to keloid scars. The scars may show more than the loss did.
• 未控制的慢性病。严重心脏病、糖尿病、凝血问题等，会增加手术风险。Uncontrolled long-term illness. Serious heart disease, diabetes or clotting problems raise the surgical risk.

第一步是由医生做毛囊检测，看供区的密度和发径。The first step is a follicle check by a doctor, measuring donor density and hair thickness.

可以。女性的发际线和密度是常见的情况，前提同样是供区充足、脱发稳定。Yes. Women's hairline and density cases are common, with the same conditions: enough donor hair and stable loss.

没有固定年龄。但脱发还没稳定的年轻人，通常建议先观察，由医生判断。No fixed age. Young people whose loss has not settled are usually advised to wait, and a doctor makes that call.

活动期不可以。头癣是真菌感染。手术要在头皮上开几百个微小创口，真菌会扩散到移植区，毛囊在感染的头皮上也很难存活，术后感染的风险成倍增加。Not while it is active. Scalp ringworm is a fungal infection. Surgery opens hundreds of tiny wounds, the fungus can spread into the grafted area, follicles struggle to survive on infected skin, and the risk of infection afterwards multiplies.

1. 先看皮肤科医生确诊：是真菌性头癣，还是脂溢性皮炎或银屑病。处理方式完全不同。See a dermatologist to confirm what it is: fungal ringworm, seborrhoeic dermatitis or psoriasis. Each is handled differently.
2. 按医嘱完成抗真菌治疗，通常需要几周。Complete the antifungal treatment as prescribed, usually a few weeks.
3. 复查，确认没有活动性感染。Get rechecked to confirm there is no active infection.
4. 稳定观察几个月没有复发，再和植发医生谈时机。Stay clear for a few months, then discuss timing with the transplant doctor.

分辨一下：真菌性头癣有环形红斑、脱屑、断发。脂溢性皮炎是油腻、黄色鳞屑、间歇性痒，发作期同样不能做。银屑病是银白色鳞屑斑块，属于免疫疾病，要非常谨慎评估。Telling them apart: ringworm shows ring-shaped red patches, scaling and broken hairs. Seborrhoeic dermatitis is greasy with yellow scales and itching that comes and goes, and also rules out surgery while flaring. Psoriasis shows silvery plaques and is an immune condition that needs very careful assessment.

先分清是哪一种头皮屑。First work out which kind of dandruff it is.

• 普通干性头屑。白色、细碎、干燥，没有红斑和油腻感。多数是头皮干燥或换季，不影响植发。Ordinary dry dandruff. White, fine, dry flakes with no redness or greasiness. Usually a dry scalp or a change of season, and no barrier to a transplant.
• 脂溢性皮炎。油腻、黄色鳞屑、间歇性痒，可能有红斑。这是炎症。发作期不能植发：炎症环境会明显降低毛囊存活率，创口会加重炎症，术后复发也会让原生发继续掉。Seborrhoeic dermatitis. Greasy, yellow scales, itching that comes and goes, sometimes red patches. This is inflammation. No surgery while it is flaring: inflamed skin lowers follicle survival, the wounds can worsen the flare, and a later flare keeps thinning the original hair.

经过规范治疗、炎症完全消退后可以做。标准很简单：头皮不红、不痒、不油、没有明显鳞屑，并且稳定了一段时间。术前多久要停用药用洗剂或含激素的药，由医生告诉你。术后皮炎还是要长期控制，否则会影响效果。Once it has been treated and has fully settled, surgery is possible. The test is simple: no redness, no itch, no grease, no obvious scaling, and stable for a while. The doctor tells you how long before surgery to pause medicated shampoos or steroid products. Afterwards the dermatitis still needs long-term control, or it will affect the result.

成活的毛囊基本不会再掉。它们来自后脑，天生对 DHT 不敏感，移到新位置后保留原来的性格。Follicles that take are expected to keep growing. They come from the back, are insensitive to DHT by nature, and keep that behaviour in their new place.

但你仍然会经历看起来“在掉”的阶段：术后第 2 到 8 周，移植的头发陆续脱落，这是正常的休止期脱发，毛囊还在。第 2 到 3 个月新发长出，逐渐变粗；第 6 个月看得见密度；12 到 18 个月是最终效果。You still go through a phase that looks like loss: in weeks 2 to 8 the transplanted hairs shed. That is normal resting-phase shedding, and the follicles stay. From months 2 to 3 new hair grows and thickens, density shows by month 6, and the final result arrives at 12 to 18 months.

真正会继续掉的是原生发。植发只处理移植的区域；周围没有移植的头发，如果脱发的原因没有控制，还会继续变少。医生在设计时会考虑这一点，也会和你谈要不要长期维持。没有人能保证每一个毛囊都存活，成活率因人而异；术后护理、作息和头皮状况都有影响。What does keep thinning is the original hair. A transplant only treats the grafted area; the untreated hair around it goes on thinning if the cause is not controlled. The doctor plans for this and discusses whether long-term maintenance is needed. No one can promise every follicle will survive. Survival varies from person to person, and aftercare, sleep and scalp health all play a part.

不是每个人都要，但如果你是雄激素性脱发，很可能需要长期维持。原因一句话：植发只管已经秃的地方，不管你未来还会秃的地方。Not everyone, but with pattern hair loss you will most likely need long-term maintenance. In one line: a transplant covers where you have already lost hair, not where you will lose it next.

移植的毛囊不受 DHT 影响，种上去不会掉。头顶那些没被移植的原生发，仍然每天受 DHT 影响。放着不管，几年后会出现“孤岛”：移植区完好，周围退了，比植之前更尴尬。The moved follicles are DHT-insensitive and stay. The original hair on top that was not moved is still under DHT every day. Left alone, an island forms within a few years: the grafted area intact and the hair around it gone, which looks worse than before.

• 通常不需要：本身没有雄激素性脱发、只做发际线微调；外伤或烧伤的疤痕修复；脱发已经稳定多年、原生发没有继续变细。Usually not needed: a hairline refinement with no pattern loss; scar repair after injury or burns; loss that settled years ago with no further thinning.
• 通常需要：年轻男性的雄激素性脱发，发际线还在后移、头顶还在变稀；大面积的头顶稀疏；拿不准是天生发际线还是在后退的，由医生判断。Usually needed: pattern loss in younger men whose hairline is still receding or crown still thinning; wide crown thinning; and anyone unsure whether a hairline is natural or receding, which a doctor decides.

用什么、用多久，是注册医生的处方决定，我们不卖药。一个简单的信号：如果没有植发的区域掉发明显比平时多、持续两周以上，告诉医生。What to use and for how long is a registered doctor's prescription; we do not sell medicines. One simple signal: if the untreated areas shed noticeably more than usual for over two weeks, tell the doctor.

有，而且两大类药的副作用很不一样，这正是它们要由医生处方和跟进的原因。Yes, and the two main kinds behave very differently, which is why a doctor prescribes and follows them.

• 口服药从源头减少 DHT。多数人没有感觉；少数人会出现性欲或性功能方面的变化、情绪变化，通常停药后可逆。用药前后医生会安排基础检查。The oral kind lowers DHT at its source. Most people notice nothing; a minority report changes in libido or sexual function, or in mood, usually reversible after stopping. The doctor arranges basic checks before and during use.
• 外用药涂在头皮，促进局部生长。常见的是头皮痒、发红、脱屑、出油。用药头几周可能先多掉一阵，那是旧发被新发顶出来，不是在变差。它只管“长”，不管“防”，停用后新生的头发会在几个月内回落。The topical kind goes on the scalp to encourage local growth. Common effects are itching, redness, flaking and oiliness. In the first weeks shedding can increase as old hairs are pushed out by new ones, which is not the treatment failing. It helps hair grow but does not block DHT, so new growth recedes within months of stopping.

该不该用、用哪一种、剂型怎么选，由注册医生根据你的情况决定。出现任何不舒服，及时告诉医生，不要自己停药或加量。Whether to use either, which one and in what form is a registered doctor's decision for your case. Report anything that feels wrong to the doctor rather than stopping or increasing on your own.

效果差别很大，证据的等级也差别很大。They differ a lot, in effect and in evidence.

• 外泌体。研究还在早期，不是公认的标准治疗。任何注射用的产品都必须是在马来西亚注册的产品。对任何“数据”保持谨慎。Exosomes. Still early research, not an established treatment. Anything injected must be a product registered in Malaysia. Treat any claimed data with care.
• PRP，自体富血小板血浆。抽自己的血，分离后注射到头皮。证据不一：部分人掉发减少、绒毛变粗，部分人没有明显变化。需要多次疗程并定期巩固，适合作为辅助，不能替代对仍在变细毛囊的医学治疗。PRP, platelet-rich plasma from your own blood. Drawn, spun and injected into the scalp. Evidence is mixed: some people shed less and see fine hairs thicken, others see no clear change. It takes several sessions plus top-ups, and works as a supplement, not a replacement for medical treatment of follicles that are still thinning.
• 草本护发、中药洗头。能改善头皮环境、减少断发，是日常养护的加分项。没有证据能让已经闭合的毛囊重新长发。Herbal care and herbal washes. Improve the scalp and reduce breakage, a fair addition to daily care. No evidence that they reopen a closed follicle.
• 生发水、头皮精华（Tonic）。看成分。含注册药物成分的就是药，去药房、问药剂师。含咖啡因、多肽之类的属于养护，可能让发根结实一点，对闭合的毛囊无能为力。Tonics and scalp serums. It depends on the ingredient. One containing a registered medicine is a medicine, bought at a pharmacy with a pharmacist's advice. Caffeine, peptide and similar blends are care products that may firm the root a little and do nothing for a closed follicle.

这些方法只对还活着的毛囊起作用。毛囊已经没了，只有把毛囊移过去，也就是植发。All of these act only on living follicles. Where the follicle is gone, the only way to put hair there is to move follicles in, which is what a transplant does.

不能。头发只从毛囊长出来。毛囊还在、只是变细变短（萎缩），药物、PRP 之类可以让它粗回来一些。毛囊已经闭合、被疤痕取代，或者那块头皮光滑发亮多年，涂什么、打什么都长不出头发。No. Hair only grows from a follicle. If the follicle is still there but shrunken, producing finer and shorter hair, medication or PRP can thicken it again. If it has closed, been replaced by scar, or the skin has been smooth and shiny for years, nothing applied or injected will grow hair there.

怎么知道毛囊还在不在？医生用皮肤镜看头皮：还有细软的绒毛，就是毛囊还在；看不到毛孔开口，多半已经没了。这一步决定你该先治疗，还是该考虑植发。How to tell: a doctor looks at the scalp under a dermatoscope. Fine, soft vellus hairs mean the follicle is still there; no visible pore openings usually mean it is gone. That check decides whether to treat first or to consider a transplant.

不会。生长发生在皮肤里的毛囊，剪刀碰不到。No. Growth happens in the follicle under the skin, where scissors never reach.
