🌍 Why Sleep Matters for Hair Health

Sleep isn’t just about rest—it’s about repair. During deep sleep:

• 🧬 Cell regeneration occurs, including hair follicle cells.
• 💉 Growth hormones peak, stimulating hair growth.
• 🩸 Blood circulation improves, delivering nutrients to the scalp.
• 🌱 Stress hormones decrease, reducing hair shedding.

👉 Poor sleep = poor hair health.

🧳 Pillowcase Fabrics and Their Impact

Not all pillowcases are created equal. Here’s how different fabrics affect your hair:

Fabric 🛏️	Impact on Hair 💇	Pros ✅	Cons ❌
Cotton	Absorbs moisture	Affordable, breathable	Causes friction, frizz, dryness
Silk	Smooth surface	Reduces breakage, luxurious	Expensive, delicate care
Satin	Similar to silk	Affordable, hair-friendly	Less breathable
Polyester blends	Rough texture	Cheap, durable	Static, tangles
Bamboo fabric	Soft & eco-friendly	Moisture-wicking, gentle	Less common, pricier
