Hello Capilli AI Community,

We often focus on hair products and routines, but how well you sleep may be just as important. Your hair follicles are deeply connected to your body’s internal rhythms, and the quality of your rest directly affects how your hair grows, repairs, and thrives.

In this edition of Foundations of Healthy Hair, we explore the science behind sleep and hair regeneration, the hidden damage caused by sleep deprivation, and practical ways to protect and nourish your hair overnight.

Why Sleep Matters for Hair

Sleep is when your body shifts into deep cellular repair mode, and that includes your hair. During deep sleep, your system restores balance to the hormones and nutrients responsible for healthy follicle activity and new hair growth.

• Growth hormones increase

• Cortisol (stress hormone) decreases

• Blood flow to the scalp improves

• Nutrients are delivered more efficiently to hair roots

When sleep is disrupted, this balance breaks down, and so does your hair’s support system.

The Effects of Poor Sleep on Hair

Chronic lack of sleep doesn’t just affect your skin and mood. It can directly lead to:

• Hair thinning due to imbalanced hormones

• Increased shedding and slowed growth

• Weakening of follicles over time

• Higher risk of scalp inflammation and dryness

If you’re doing all the “right” things but still struggling with hair issues, your sleep habits might be the missing link.

Nighttime Tips to Support Hair Recovery

• 🌿 Silk or satin pillowcases – Minimise friction and reduce overnight breakage

• 🛁 Don’t sleep with wet hair – Hair is more fragile when damp

• 🧴 Overnight hair masks or oils – Restore hydration and support the cuticle

• 🧘‍♀️ Evening wind-down routines – Lower cortisol and support hormonal balance

• 🪮 Gentle nighttime detangling – Prevent tension and knots while you sleep

Practical Takeaways:

• Prioritise deep, consistent sleep to support hair growth and strength

• Protect your hair physically with better fabrics and gentle styling

• Consider overnight care as part of your long-term hair strategy

What’s Next?

In our next edition of Foundations of Radiant Skin, we’ll explore how your environment, like pollution and air quality, impacts your skin’s long-term health and what you can do about it.
