⭐ Is there a foundation or a tonic? Which one do I start with?⭐ 有「foundation 打底乳」或「tonic 爽肤水」吗？先用哪一支？
There is no foundation, no tonic, no toner — both sizes contain the same Bird's Nest SAO scalp serum. MY SAO comes in two sizes: 5 mL to try, and 80 mL, made in Japan for the long run. Start with the 5 mL — about fifteen days on a hairline or parting, which lands on your first comparison.没有「foundation 打底乳」、没有「tonic 爽肤水」、也没有「化妆水」 —— 两个规格装的都是同款燕窝 SAO 头皮精华。MY SAO 只有两个规格：5 mL 先试，80 mL · 日本制造 长期用。先由 5 mL 开始——搽发际线或分界约十五天，正好到你第一次对比那天。
How long does one bottle last?一支能用多久？
It depends on the area you cover — about 10 mL a month on a hairline or parting, about 25–30 mL on a whole scalp. One 5 mL lasts about fifteen days on a hairline, about six days on a whole scalp. One 80 mL lasts about three months on a whole scalp, about eight months on a hairline.取决于涂抹面积——发际线或分界每月约 10 mL，全头每月约 25–30 mL。一支 5 mL 搽发际线约十五天，全头约六天。一支 80 mL 全头约三个月，发际线约八个月。
How much should I apply?每次涂多少？
Press point by point over the area you want to work on — hairline, parting or crown — covering it evenly. You don't need to count sections. About 25–30 mL a month, varying with the area. Apply to the scalp, not the hair.沿需要改善的位置（发际线、发缝或头顶）逐点按压，均匀覆盖，不必分区计数。每月约 25–30 mL，视面积而定。涂在头皮上，不是头发上。
Wet hair or dry hair?湿发还是干发使用？
On a dry scalp. Wash, dry, then apply — wet hair dilutes the essence.头皮干爽时使用。洗头、吹干，再涂——湿发会稀释精华。
How often, and when will I notice anything?多久用一次？什么时候会看到变化？
Once a day at a fixed time. Women usually notice first changes around day 15–21 — some earlier, some later, and some see none. Men respond more slowly and need to keep going for 90 days or more before a record can be read. Individual results vary.每天固定一个时间使用一次。女性通常在第 15–21 天看到最初变化——有人更早、有人更晚，也有人看不到。男士反应较慢，需持续 90 天以上才能判读。个人效果因人而异。
Do I need to take a Day 0 photo before starting?开始使用前要拍 Day 0 照片吗？
Yes — it's what makes the record worth keeping. Before your first application: use a natural mole, scar or whorl as your marker (don't draw one); same lamp, same time of day; eyebrows just in frame; no beauty mode, HDR, filter or flash. Retake on day 15, 30, 60 and 90. The photos stay on your own phone.要——有了它，这份记录才有意义。第一次使用前：用天生的痣、疤或发旋定位（不要另外画记号）；同一盏灯、同一时段；眉毛刚好入镜；关掉美颜、HDR、滤镜，不用闪光灯。第 15、30、60、90 天再各拍一次。照片留在你自己手机里。
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？
Once a day, on a dry scalp after washing and drying. Press point by point over the area, covering it evenly; press in gently with your fingertips. No rinsing — style as usual.每天一次，洗头吹干、头皮干爽时使用。逐点按压、均匀覆盖需要的位置，用指腹轻按至吸收。免冲洗，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？
Yes. Men respond more slowly than women and need to keep going for 90 days or more before a record can be read. Message us if you'd like help deciding where to apply.可以。男士反应较女士慢，需持续 90 天以上才能判读。如需建议涂在哪里，请联系我们。 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 WhatsApp purchases (public code), WhatsApp'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（WhatsApp 公开 直购）适用 WhatsApp 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。

What's the active ingredient?关键成分是什么？
SAO (sialo-oligosaccharide) from swiftlet nest — on the ingredient list as Hydrolyzed Swiftlet Nest Extract. The raw material is made by a patented manufacturing method; the patent covers how it is made, not what the product does. Contains bird's nest extract, a known allergen. More on Ingredient & Patent.取自金丝燕窝的 SAO（唾液酸寡糖），成分表名称为「水解小雨燕窝提取物」。原料以专利制法生产；专利保护的是怎么做，不代表产品功效。含燕窝提取物（已知致敏原）。详见成分与专利。 Why don't you quote clinical figures?为什么不引用临床数字？
Because the randomised, double-blind study we hold was run on the mainland China version of MY SAO — with Thuja orientalis leaf extract added, using a pilot batch at a dose above everyday use. Its figures don't transfer to the version sold here, so we don't quote them. See Studies & Records.因为我们手上的随机双盲研究，对象是 MY SAO 中国内地版——另加侧柏叶提取物，用的是中试批次、用量高于日常零售用量。它的数字不能套到本站所售的版本上，所以我们不引用。详见研究与记录说明。 Does the product contain growth factors (FGF, IGF, etc.)?产品本身含生长因子吗？
No. The product contains no growth factors.不含。产品不含任何生长因子。
Is the product approved by SG HSA?已通过新加坡 HSA 审批吗？
Cosmetics in Singapore are notified, not approved. Notification is not an approval or an endorsement by HSA. The product is sold as a cosmetic and is not a medicinal product.新加坡化妆品采取通报制，不是审批。通报并不代表 HSA 批准或认可。本品作为化妆品销售，不属于药品。
Which studies exist, and which version did they use?有哪些研究？用的是哪个版本？
The studies we hold were all run on the mainland China version of MY SAO (with Thuja orientalis leaf extract added), so we don't quote their figures. What we can show for the Singapore version is the Daily Vanity reader trial (sponsored, self-assessed) and individual records. The full account is on Studies & Records.我们手上的研究，对象都是 MY SAO 中国内地版（另加侧柏叶提取物），所以本站不引用其数据。能给新加坡版看的，是 Daily Vanity 读者试用（合作内容、受试者自评）与个人记录。完整说明见研究与记录说明。 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。
