Use with caution
You may turn less minoxidil into its active form, so it may regrow less hair. It can still help. If results are poor, ask your doctor about other options.
The genes behind this label
The guidelines read one gene for minoxidil. Each card shows the two copies this person inherited and what they mean.

- In plain words
- You may turn less minoxidil into its active form, so it may regrow less hair. It can still help. If results are poor, ask your doctor about other options.
- What it means
- Your SULT1A1 result suggests reduced enzyme function. This enzyme helps activate topical minoxidil (Rogaine). Reduced activation may limit hair regrowth, even with consistent use. This result does not rule out benefit from treatment.
- What the research suggests
- If hair growth is limited despite consistent use, discuss additional or alternative treatments with your clinician.
