Where to Apply — and How Much涂在哪里、涂多少
Press point by point over the area you want to work on — hairline, parting or crown — and cover it evenly. You don't need to count sections.
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。
Full-scalp use is about 25–30 mL a month; a smaller area, such as the hairline alone, uses less. Whatever area you choose, start your photo record on day 0 in that same area.
全头使用每月约 25–30 mL；只涂发际线等较小面积会少一些。不管选哪个位置，第 0 天就在同一位置开始拍照记录。
Take Your Day 0 Photo — Before You Apply Anything第一次涂之前，先拍一张 Day 0 照片
The Day 0 photo is the single most important step of the whole routine. Without it, you have nothing to compare against — and four weeks later, you will not be able to tell yourself whether anything actually changed.
Day 0 照片是整个仪式中最重要的一步。如果没有它，你就没有任何「对照基线」——四周之后，你自己也无法判断到底有没有变化。
Five rules that make Day 0 a real baseline:
让 Day 0 真正成为基线的五条规则：
- Same light. The same lamp in the same spot, at the same time of day. Turn off beauty mode, HDR and filters; no flash.同光线。同一盏灯、同一位置、同一时段。关掉美颜、HDR 与滤镜，不用闪光灯。
- Same spot. Use a natural mole, scar or whorl as your marker — don't draw one, it fades. Let your eyebrows just enter the frame: that fixes both angle and distance.同位置。用天生的痣、疤或发旋定位——不要另外画记号，记号会褪。让眉毛刚好入镜：角度和距离一起固定了。
- Same time of day. Morning, before any styling product. Hair behaves differently at 8am vs 8pm.同时段。建议晨起、未上任何造型品。早 8 点和晚 8 点的发型状态是不一样的。
- Dry, parted hair. Towel-dry; part the hair to expose the hairline. Wet hair flatters everything and makes comparison meaningless.干发、分缝。毛巾擦干；分缝露出发际线。湿发会让一切看起来更顺，导致后续对比失效。
- No filter, no editing. Original camera image only. Save the file unchanged. If you ever want a refund under our promise, this honest photo is the proof you'll need.不修图、不滤镜。仅原相机原图。文件不要修改保存。如果将来需要按我们的承诺退款，这张诚实的照片正是你需要的凭据。
After day 0, repeat the same photo on day 15 · 30 · 60 · 90 and put them side by side. Women usually notice first changes around day 15–21 — some earlier, some later, some none. Men respond more slowly and need 90 days or more. Your photos stay on your own phone.
第 0 天之后，在第 15 / 30 / 60 / 90 天各拍一次同样的照片，并排来看。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 90 天以上。照片留在你自己手机里。
Quick check: Have you taken your Day 0 photo yet? If not — stop, take it now, and then start the routine.
检查一下：你拍 Day 0 照片了吗？没有的话——先停下，现在就拍，然后再开始仪式。
