📦 Bottle & Set Layout📦 套装结构与瓶身使用顺序
⭐ Which bottle is the "main" one? Is there a foundation or tonic?⭐ 套装里哪一瓶是主瓶？有「foundation 打底乳」或「tonic 爽肤水」吗？
There is no foundation, no tonic, no toner in the set — every bottle contains the same Bird's Nest SAO scalp serum. The PROSAO Flagship Set comes in 5 pieces / 3 boxes. Use them in order:
1️⃣ Box 1 · Main Bottle (high-concentration, 25 mL) — open this first
2️⃣ Box 2 · Continuation Bottle (25 mL) — switch to this when Box 1 finishes
3️⃣ Box 3 · 3 Travel Minis — your portable on-the-go kit
👉 See the visual use-order diagram.套装里没有「foundation 打底乳」、没有「tonic 爽肤水」、也没有「化妆水」 —— 每一瓶都是同款燕窝 SAO 头皮精华。PROSAO 旗舰套装共 5 件 / 3 个外盒。使用顺序：
1️⃣ 1 号盒 · 主瓶（高浓度 25 mL）—— 先用这一瓶
2️⃣ 2 号盒 · 续用瓶（25 mL）—— 1 号瓶用完后切换到这一瓶
3️⃣ 3 号盒 · 3 支便携小装 —— 出门随身携带
👉 查看完整使用顺序图。 How many pumps does each bottle hold? How long does it last?每瓶能按多少下？能用多久？
Anchor: 5 mL = 700 pumps (1 pump ≈ 0.0071 mL · 1 mL ≈ 140 pumps).
Pumps per pack:
· 5 mL → 700 pumps
· 10 mL → 1,400 pumps
· 25 mL → 3,500 pumps
· 35 mL → 4,900 pumps
How long? At the recommended 40 pumps/day (10 pumps × 2 sides × 2 sessions): 25 mL ≈ 87 days (~3 months). At lighter 20 pumps/day (once daily): 25 mL ≈ 175 days (~6 months).
👉 Full pump calculator: how-to.html.基准：5 mL = 700 下（1 下 ≈ 0.0071 mL · 1 mL ≈ 140 下）。
各规格按压数：
· 5 mL → 700 下
· 10 mL → 1,400 下
· 25 mL → 3,500 下
· 35 mL → 4,900 下
能用多久？按推荐 40 下/天（双侧各 10 下、早晚各一次）：25 mL ≈ 87 天（约 3 个月）。按轻度 20 下/天（每天 1 次）：25 mL ≈ 175 天（约 6 个月）。
👉 完整按压计算器：how-to.html。 How many pumps per side, per session?每次每侧应该按几下？
· Maintenance: 5 pumps per side
· Best routine: 10 pumps per side (20 per session)
· Full-scalp coverage: up to 100 pumps — recommended only after the hairline test shows a result
Apply twice daily, morning + night, directly onto the scalp (not the hair strands).· 维稳：每侧 5 下
· 最佳：每侧 10 下（双侧共 20 下）
· 全头覆盖：最多 100 下 —— 建议先完成发际线测试、看到效果后再扩展
早晚各一次，直接点涂头皮（不是发丝）。
Wet hair or dry hair?湿发还是干发使用？
Always on a fully dry scalp. Wet hair dilutes the serum and washes away active ingredients. Correct order: wash → blow-dry completely → apply. This is the #1 reason a routine doesn't show results.一定在头皮完全干燥时使用。湿发会稀释精华、冲走有效成分。正确顺序：洗发 → 风筒吹至全干 → 涂抹。这是「routine 没效果」的第一大原因。
Can I use it only at night, once a day?只在晚上用、每天一次可以吗？
Yes — once-a-day works. Your bottle just lasts twice as long. But twice daily (AM + PM) gives the fastest visible change. Most users see change at Day 30 with twice-daily use; once-daily users typically see change between Day 45 and Day 60.可以——每天 1 次也有效，瓶子用得更久。但早晚各一次会更快看到变化。大多数用户在每天两次的频率下，30 天看到变化；每天一次的用户通常在第 45–60 天之间看到变化。
Do I need to take a Day 0 photo before starting?开始使用前要拍 Day 0 照片吗？
Strongly recommended — even if you're not enrolled in the Ambassador program. On Day 0, before your first application, take a hairline photo with: same lighting (window daylight), same angle (front-on, hairline visible), no filter, no editing. Re-take at Day 15, Day 30, Day 60. At Day 30 you can place them side by side — your own mirror tells the truth.强烈建议——即使不参加体验官计划。第一次使用前，拍 Day 0 发际线照片，注意：同光线（窗边自然光）、同角度（正面、发际线完全露出）、不修图、不滤镜。第 15、30、60 天再各拍一次。第 30 天并排对比 —— 你自己的镜子告诉你真相。
Product & Ritual产品与仪式
What is the texture and how does it feel?质地如何？使用感如何？
Water-light, transparent, almost mist-like. It absorbs in roughly 60 seconds and leaves no residue. Compatible with normal styling.如水般清透、近乎雾感，约 60 秒吸收，零残留，不影响日常造型。
Does it smell?有香味吗？
A whisper-soft, neutral scent. We tuned the formula not to compete with your perfume.微风般淡香、中性气息，刻意不抢你日常用香的存在感。
When and how should I apply it?什么时候、怎么用？
On a clean, towel-dried scalp, twice daily. About 30 presses each time, distributed along hairline and crown. Massage 60 seconds with fingertips, then style as usual.洗后毛巾擦干、早晚各一次，每次 30 下，分布在发际线与头顶；指腹按摩 60 秒，照常造型。
Will it weigh hair down?会让头发塌吗？
No. The texture is too light to interfere with styling. Many users layer it under blow-dry or styling product without issue.不会。质地过轻，不干扰造型，多数用户在吹整或造型品之前使用都无影响。
Is it suitable for men?男士可以用吗？
The product was primarily designed with female scalps in mind. We are happy to advise male customers via Contact Us; please reach out before buying.本品主要面向女性头皮设计。男士请先联系我们，由顾问评估再下单。 Suitable during pregnancy / breastfeeding?孕期 / 哺乳期可以用吗？
Our composition is hormone- and drug-free, but we recommend you check with your obstetrician/healthcare provider before introducing any new topical product during pregnancy or breastfeeding. We will not advise medically.配方无激素、无药物成分，但孕期/哺乳期是否引入新外用产品请先咨询妇产科医师/医疗专业人士。我们不提供医学建议。
Refund & Service退款与服务
How does the 35-day promise actually work?35 天承诺具体如何运作？
From day of receipt, you have 35 days. If the texture, scent, finish, or ritual experience does not meet your standards, contact us with order ID and product photos. We arrange a full refund or one-for-one replacement, your choice. Open and used bottles accepted.收货起 35 天内，若质地、香气、收尾感或仪式体验未达预期，凭订单号与产品照片联系我们，可选全额退款或一对一换货；已开封并使用的瓶身可受理。
⭐ Can I get a refund if I don't see results after using the full cycle?⭐ 用完一个完整周期后没看到效果，能退款吗？
Yes — under the Ambassador program (Tier 1, 2, or 3). If you have a clear Day 0 baseline photo and no visible change after the full cycle, we will arrange a refund. Two conditions:
1️⃣ You're enrolled in one of the Ambassador tiers (Tier 1 Ultimate / Tier 2 Tracker / Tier 3 Reviewer)
2️⃣ You sent us your Day 0 photo BEFORE the first application
For direct Shopee purchases (40% off public code), Shopee's standard return policy applies. Cosmetic — individual results may vary.可以——参加体验官计划（Tier 1、2 或 3）的客户。如有清晰的 Day 0 基线照片，使用满整个周期仍未看到变化，我们会安排退款。两个条件：
1️⃣ 已加入体验官某一级别（Tier 1 终极 / Tier 2 追踪者 / Tier 3 测评者）
2️⃣ 已在第一次使用前发送了 Day 0 照片
非体验官（Shopee 公开 40% off 直购）适用 Shopee 标准退货政策。化妆品类，效果因人而异。
Can you guarantee my hair will look fuller?能保证我头发会显得更丰盈吗？
No. Hair behaviour is shaped by hormones, age, sleep, stress, genetics, and many factors a cosmetic cannot address. Under SG HSA cosmetic regulations, we may not — and so will not — promise a specific biological outcome. We promise the experience we can deliver: texture, ritual, finish, service. The refund is tied to that experience.
不能。头发受激素、年龄、睡眠、压力、基因等多因素影响，远超化妆品介入范围。新加坡 HSA 化妆品法规也不允许我们承诺特定生物学结果，我们因此不会作此承诺。我们承诺的是可控的体验——质地、仪式、收尾感、服务，退款也据此而定。
Where can I buy authentic MYSAO?在哪里能买到正品？
Our official Shopee Singapore storefront and authorised partners. Avoid third-party listings without our authorisation badge.官方 Shopee 新加坡旗舰店与授权合作伙伴。请避开未授权第三方店铺。
Do you ship outside Singapore?是否海外发货？
Cross-border shipping varies by region. Please contact us with your destination so we can confirm the right channel.跨境发货因地区而异，请联系我们并告知目的地，我们将确认渠道。 Science & Compliance科学与合规
What's the active ingredient?关键成分是什么？
The hero ingredient is Hydrolyzed Bird's Nest Extract — a heritage East Asian ingredient, refined into a clear cosmetic-grade fluid. Full ingredient science is on our Research Hub.核心成分是水解燕窝精萃——东方传统成分，提炼为清透的化妆品级精华。完整科学请见研究中枢。 Why is the science on a separate page?为什么把科学放在另一页？
SG HSA cosmetic rules forbid medical or therapeutic claims on product pages, even when the underlying ingredient has published research. Rather than bury our research, we built a clearly labelled Research Hub for it. Product pages stay product pages; science stays science.新加坡 HSA 化妆品法规禁止产品页作出医疗/治疗主张——即便原料拥有已发表研究。我们没有把研究藏起来，而是另建了一座明确标示的研究中枢：产品页面保持产品的本分，科学保持科学的本分。 Does the product contain growth factors (FGF, IGF, etc.)?产品本身含生长因子吗？
No. The product does not contain FGF-7, HGF, IGF-1, EGF or any other growth factor. Published cellular research describes the ingredient supporting endogenous expression in vitro — but the finished cosmetic does not contain or supply growth factors.不含。产品不含 FGF-7、HGF、IGF-1、EGF 或任何生长因子。已发表细胞研究描述的是该成分在体外支持内源表达——但成品化妆品本身既不含、也不补充生长因子。
Is the product approved by SG HSA?已通过新加坡 HSA 审批吗？
Cosmetics in Singapore are notified, not "approved" in the medicinal sense. The product is notified as a cosmetic and is sold strictly as such. The product is not a medicinal product and makes no therapeutic claims.新加坡化妆品采取「备案」制，并非医药意义上的「审批」。本品按化妆品备案，亦严格作为化妆品销售；不属于药品，不作任何治疗主张。
Are there clinical trials?有临床试验吗？
There are observational records and in vitro mechanism studies for the ingredient, conducted outside Singapore. Records are listed on the Clinical & Compliance Archive for educational reading. Those records do not constitute a SG-market efficacy claim for the MYSAO finished product.该成分在新加坡境外有观察性记录与体外机理研究，详见临床与合规档案，仅作教育阅读。它们不构成 MYSAO 成品在新加坡市场的功效主张。 Daily Vanity & PricingDaily Vanity 与价格

Under SG SCAP / ASAS rules, we are required to state — and we agree — that there is no scientific proof that any product (except certain registered medicinal products) or service can retard hair loss or promote hair growth. MY SAO is a cosmetic. We describe what we can: the appearance of hair density, scalp condition, the feel of the texture, and DV reader-reported experience. Individual results may vary.
根据新加坡 SCAP / ASAS 法规，我们须声明（也认同）：没有科学证明任何产品（某些注册药品除外）或服务可以延缓脱发或促进毛发生长。MY SAO 为化妆品。我们能描述的是：毛发密度的外观、头皮状态、质地的肤感，以及 DV 读者反馈的体验。实际效果因人而异。
