The patents protect how the SAO raw material is made. They are not a certification, and they do not say what the product does.专利保护的是 SAO 原料的制造方法。它不是认证，也不代表产品功效。
Invention patents in China, the US and Japan, with extension registrations in Hong Kong and Macau. They do not extend to Singapore or Malaysia.中、美、日三国发明专利，港、澳两地区延伸登记；不覆盖新加坡与马来西亚。

Whether it is a single scalp treatment or a twenty-session package, you leave with no photos you can compare. We sell a documented 90 days: a baseline photo on day 0, then day 15, 30, 60 and 90 — same spot, same light. Your photos stay on your own phone, not with us. Women usually notice first changes around day 15–21.不管是一次头疗，还是二十次的疗程，离店时手上都没有一组能对比的照片。我们卖的是一个有记录的 90 天：第 0 天拍基线，之后第 15、30、60、90 天，同一位置、同一光线。照片在你自己手机里，不在我们手里。女性通常在第 15–21 天看到最初变化。
Day 0 Photo GuideDay 0 拍照指南Fast-absorbing, no greasy residue. Precision brush-tip applicator delivers serum directly to scalp. Built for Singapore's humid climate.极速吸收、不油不腻。钢笔式分缝刷头，将精华精准送达头皮，适合 SG 高湿度气候日常使用。
Drug-free · Hormone-free · Alcohol-free. Contains bird's nest extract, a known allergen — patch-test behind the ear for 24 hours before first use, and do not use if you are allergic to bird's nest or avian proteins.无药物 · 无激素 · 无酒精。含燕窝提取物，燕窝是已知致敏原——首次使用前请先在耳后小范围试用 24 小时；对燕窝或禽鸟蛋白过敏者请勿使用。

Read Full Trial阅读完整测评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. So we do not quote its figures. What we offer instead is the record you keep yourself.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。所以本站不引用它的数据。我们给你的是你自己留下的记录。
Studies & Records研究与记录说明For women whose hairline, temples or parting look thinner — through stressful periods, and with sensitive scalps. Men respond more slowly and need 90 days or more before a record can be read.适合发际线、鬓角或发缝看起来变稀的女性——高压时期与敏感头皮人群。男士反应较慢，需持续 90 天以上才能判读。
Two sizes, no bundles — 5 mL to try, 80 mL for the long run. No hidden packages, no countdown timers. Ask on WhatsApp for prices and delivery; Hong Kong sells the same two sizes.两个规格，不做套餐——5 mL 先试，80 mL 长期用。没有隐藏套餐、没有限时倒数。价钱与送货请 WhatsApp 查询；香港站卖的是同样两个规格。
What we promise is a record you can check — not a result we guarantee. The method is simple: 我们承诺的是一份你自己能核对的记录，不是一个保证的结果。方法很简单：
Baseline photo before the first application. Use a natural mole, scar or whorl as your marker (don't draw one); same lamp and time; eyebrows just in frame; no beauty mode, HDR, filter or flash.第一次使用前拍基线。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。
Photo #2 — the first comparison. Women usually notice first changes around day 15–21; some earlier, some later, and some see none.第 2 张——第一次对比。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。
Keep the record going. Put your photos side by side with day 0. Men respond more slowly — read a man's record at 90 days or later.把记录继续下去。每次与第 0 天并排看。男士反应较慢——男士的记录请在 90 天或之后判读。
Every photo is yours, on your phone, in your camera roll. We don't ask customers to send them — we want you to see the record for yourself. (Participants in our Tester Programme choose to share theirs publicly, as part of that programme.) 所有照片都在你自己的手机、自己的相册里。我们不要求顾客发给我们——我们希望你自己看到这份记录。（参加测评计划的人，是自愿把照片公开分享作为计划的一部分。）

We don't quote lab figures, mechanism studies or clinical numbers for MY SAO. The study we hold was run on the mainland China version, and findings on cells in a dish are not results on a living scalp. What we do publish: where the SAO raw material comes from, what the patents cover, and a plain account of which studies exist and which version they used. 我们不把实验数字、机理研究或临床数字当作 MY SAO 的效果来引用。我们手上的研究用的是中国内地版；离体细胞上的结果也不是活人头皮上的结果。我们公开的是：SAO 原料来自哪里、专利保护什么，以及一份写清楚「有哪些研究、用的是哪个版本」的说明。
