We're one of the very few scalp serums where female users can see the change with their own eyes. The method is simple — and brutally honest: 我们是极少数能让女性用户亲眼看到变化的头皮精华产品。方法很简单，也很诚实：
Take a hairline photo. Same light, same angle, no filter. This is your honest baseline.拍下发际线第一张照片。同光线、同角度、不修图。这是你诚实的起点。
Photo #2. You may not see a big change yet — that's normal. Hair has a 2-week growth cycle.第 2 张照片。这时未必有明显变化——这是正常的。头发有约 2 周的生长周期。
The difference is usually visible. Side-by-side with Day 0 — your own mirror tells the truth.通常已经能看到差别。与 Day 0 并排对比——你自己的镜子会告诉你真相。
Take a photo every 15 days. Every photo is yours, on your phone, in your camera roll. We don't ask you to send them — we just want you to see the truth for yourself. 每 15 天拍一张。所有照片都在你自己的手机、自己的相册里。我们不要求你发给我们——我们只希望让你自己看到事实。

Singapore HSA / ACD Appendix III / SCAP rules forbid cosmetic products from making medical or therapeutic claims, even when the underlying ingredient has a published research record. We respect that line. This product page describes only what MY SAO is — its texture, ritual, ingredients, and Daily Vanity's reader trial. The science of SAO biology, hydrolysis chemistry, lab data, and the patent record lives on a clearly labelled Research Hub, presented strictly as education. 新加坡 HSA / ACD 附录 III / SCAP 规定禁止化妆品作出医疗或治疗主张——即便其成分拥有已发表研究。本品尊重这条边界：本页只描述 MY SAO「是什么」——质地、仪式、成分、Daily Vanity 读者测评。SAO 生物学、水解化学、实验室数据、专利记录等科学内容都集中在标示明确的研究中枢，严格作为教育资料呈现。
