Your hair, on the record.

Hair changes over months, and a mirror can't show you much from one day to the next. Three photos, taken the same way, can.

No app. No uploads. Your photos stay on your phone.

How to take the photo.

1

Same place.

Stand by the same window, in daylight, at the same time of day.

2

Same part.

Comb your dry hair and part it in the same place, straight back from your forehead.

3

Same angle.

Hold your phone above your head, camera facing down, about a foot away. Use the timer, or ask someone to help.

4

Same settings.

No filter, no flash, no zoom. Take three and keep the sharpest.

Week 0, week 6, week 12.

Week 0.

Take a photo of your part from above, in daylight. Then use your first drops.

Week 6.

Take the same photo in the same spot at the same time of day. Notice how your hair looks and feels.

Week 12.

Put the three photos side by side. Then choose: a refill, or the guarantee.

What to look at.

Put the photos side by side at the same size. Look at the width of your part, how much scalp shows under the same light, and how your hair feels between your fingers. Results vary, and slow change is normal.
