Caring for your nano brows involves a few critical steps to ensure proper healing and longevity of the treatment. Here's a simple guide:

1. **Avoid Water and Sweat**: For the first week post-procedure, avoid getting your brows wet. This includes sweat, so try to avoid heavy workouts. This is to prevent the pigment from washing out of the skin.

2. **Avoid Sun Exposure**: The sun can cause the pigment to fade quickly. Wear a hat or sunglasses to protect your brows from direct sunlight, especially in the first two weeks.

3. **Don't Pick or Scratch**: As the skin heals, it may start to itch and flake. Resist the urge to pick or scratch as this can pull out the pigment and cause scarring.

4. **Use a Healing Balm**: Apply a thin layer of a healing balm or ointment recommended by your technician twice a day. This will help keep the area moisturized and promote healing.

5. **Avoid Makeup and Skincare Products**: For at least a week post-procedure, steer clear of makeup and skincare products on the brow area. These products can cause irritation and may interfere with the healing process.

6. **Touch-Up Appointment**: Schedule a touch-up appointment 4-6 weeks after the initial procedure. This allows your technician to fill in any areas where the pigment may not have taken as well.

Remember that everyone's skin is different, and healing times can vary. Always follow the advice of your brow technician, as they understand your skin type and the specific pigments used in your procedure.

It's also important to remember that nano brows, like any other semi-permanent makeup procedure, require maintenance. Regular touch-ups every 12-18 months will keep your brows looking their best.
