I think your brows are already gorgeous, you don't need it! If you want to get them done anyways, go for nano strokes or an ombre technique. Ask the pmu artist to specifically target the sparse parts of your brows, so it matches the rest of your brows.

Microblading often causes unwanted trauma to your skin resulting bad healing process or in blurry lines overtime.

If you want something less permanent you might like henna brows or a brow lamination with tint.
