Exosome Hair Before and After: How to Read the Photos

Why we show no photos

We have no photos of our own and we do not borrow clinic photos. We will publish a photo only with the clinic's written permission and the patient's consent. That rule protects patients and keeps us from presenting a clinic's best case as typical.

What makes two photos comparable

A paper from 2025 proposed standard photography protocols for hair loss because none were agreed (PMID 39152787). Imaging tools now guide clinicians to capture standard views of the scalp (PMID 37611291), which only helps if the setup is the same each time. Use this as a checklist. It is our own list, not a quotation from those papers.

• Same lighting, same angle and same distance in both photos
• Hair in the same state: dry or wet, same styling, same length and parting
• A stated time between the photos, and the number of sessions in between
• No filters, retouching or different cameras
• Any other treatment used at the same time is named
• A statement that the patient agreed to the photo being shown

Why a photo can mislead

Parting, hair length, damp hair and shadows all change how much scalp shows. Hair also thins and thickens with the seasons and with stress. The microneedling step alone may change how hair looks: in the 2026 randomized trial, the group that got microneedling with saline improved too, so a "before and after" of the whole procedure cannot show what the exosomes did (reported in PMID 42756864).

What studies measure instead

Trials use a scalp camera to count hairs per square centimetre and measure shaft width in a marked spot, then compare with a baseline or a placebo. In the 2026 randomized trial, hair density, count and shaft thickness did not differ between the exosome group and the saline group at 12 weeks (PMID 42756864). A gain of about 25 hairs per square centimetre in one retrospective study came from a starting point of about 122 and had no comparison group (via PMID 42756864).

Questions to ask a clinic about its photos

• Were these photos taken the same way, and when?
• Did the person also use another treatment?
• Do you have written consent to show them?
• What share of your patients look like this, and how do you measure that?
