💡 Device Selection
For scalp use, you need 1.5mm depth. Dermapens (electric) are easier to use than manual rollers. Replace cartridges/needles every 10-15 uses. Always sterilize with alcohol before use.
⚠️ Important Considerations
- • Use 1.5mm depth for hair loss (not shorter lengths)
- • Sterilize device with isopropyl alcohol before each use
- • Replace roller every 3-6 months or pen cartridges regularly
- • Avoid microneedling within 24 hours of applying minoxidil
