Eyebrow Hair Growth Cycle: How Long Until Regrowth?

Eyebrow hairs have a three-phase growth cycle:

• Anagen (Active Growth): ~4–6 weeks; new hair produced.
• Catagen (Transition): ~2 weeks; growth stops, follicle shrinks.
• Telogen (Resting): 3–4 months; hair remains before shedding.

After shedding, a new hair begins the cycle again.

Regrowth After Shaving

Shaving cuts hairs during anagen. Follicles must complete catagen and telogen before new growth starts.

• Noticeable regrowth: ~4–6 weeks
• Full original fullness: ~8–12 weeks

Rates vary by individual; age, genetics, hormones, health influence growth speed.
