The Science of Sleep-Time Hair Growth: How Oserth's Night Routine Maximizes Your Hair's Natural Repair Cycle

Did you know your hair grows 70% faster at night than during the day? While you sleep, your body enters a state of deep repair—and your hair follicles are no exception.

At Oserth, we've engineered night-specific treatments that work in harmony with your body's circadian rhythm to:
✔ Boost growth during peak keratinocyte activity
✔ Repair damage while friction is minimal
✔ Lock in moisture for healthier morning hair

1. The Biology of Nighttime Hair Growth

Your Hair's "Night Shift" Schedule

• 10 PM - 2 AM: Peak cell division in hair follicles (Journal of Investigative Dermatology)
• 3 AM - 5 AM: Highest sebum production for natural conditioning
• Blood flow to scalp increases by 40% during deep sleep

Why Daytime Products Miss the Window

• Actives get washed out by sweat/pollution
• UV radiation breaks down beneficial ingredients
• Mechanical damage from brushing/styling

2. Oserth's Night Repair System
