Why does hair get frizzy – and how to stop it (A comprehensive guide + FAQ)
In short: Frizz isn't about "bad luck," but about friction, moisture balance, and the hair cuticle . By reducing friction (especially at night) and keeping the cuticle smooth, you can achieve softer lengths, less "halo frizz," and a hairstyle that lasts longer. Here's a simple guide, a step-by-step routine, and nighttime solutions that make a noticeable difference.

What exactly is friss?
Frizz occurs when the hair cuticle lifts and becomes uneven. In healthy hair, the cuticles lie flat – like roof tiles – which locks in moisture and gives a shiny surface. When the cuticle opens, moisture escapes or is unevenly absorbed from the air. The hair fiber swells, the strands repel each other, and the surface becomes rough instead of smooth.
Common causes of chills
- Friction: Coarse textiles (especially cotton), terry towels, and harsh brushing lift the stratum corneum.
- Imbalanced moisture: Too frequent washing, harsh shampoos, and high heat deplete the hair; humid air causes the strands to swell.
- Porosity & damage: Bleaching, heat, and tight hairstyles increase porosity – the hair absorbs/loses moisture unevenly.
- Towel drying: Rubbing hard roughens the hair cuticle even before styling.
- Nighttime habits: 6–8 hours against a cotton pillow creates thousands of micro-frictions that cause frizz and wear and tear.
Why does the chill start at night?
Most people try to "rescue" their curls in the morning. But much is decided during the night . Cotton is absorbent and textured: it draws out moisture and creates friction as you turn over. You wake up with drier roots, "halo-frizz" around the crown, and a hairstyle that requires more work.
The routine that stops frizz (all hair types)
Small, consistent steps yield the best results. Adapt to your hair, but start with this:
- Wash gently: Use a mild, sulfate-free shampoo. Focus on the scalp, not the lengths. Fine/oily hair: every 2-3 days. Thick/curly/coily hair: wash less frequently; co-wash in between if needed.
- Balancing conditioner: Seal the cuticle with conditioner. Detangle with a wide-tooth comb after the conditioner has set. Balance humectants (e.g., glycerin), emollients (oils), and proteins (silk/keratin) according to porosity.
- Gentle drying: Squeeze out excess water and pat dry with a smooth T-shirt or soft microfiber cloth. Avoid harsh twisting and rubbing.
- Seal on damp hair: When hair is ~80% dry: leave-in + light seal. Fine hair: light serum/milk. Wavy/curly: cream + gelcast. Coily: cream + oil (LCO/LOC).
- Low heat, always heat protectant: Air dry or diffuse cool. When using tools: ~180–185 °C and heat protectant.
- Protect the night: Reduce friction and moisture loss while you sleep – this is where you make the biggest difference against the chill.
The Silk Solution – pillowcase & silk bonnet
Change the surface your hair rests against. Instead of cotton – which absorbs moisture and creates friction – silk allows your hair to glide smoothly and retain its natural oils.

The effect? Smoother skin, less friction, a more even moisture balance – and calmer mornings.
Common mistakes to avoid
- Solving the frizz in the morning: Without night protection, the problem will return every night.
- Overdose of protein/oil: Imbalance leads to brittleness or coating that still looks frizzy.
- Heat without protection: A single blow-dry without protection can lift the stratum corneum for weeks.
- Terry cloth and cotton everywhere: Switch to smooth textiles where you can – especially on the pillow.
- Brush dry curls/coils: Detangle in the shower with conditioner; refresh with water + leave-in.
FAQ – Frequently Asked Questions about frizz and silk
Yes. Silk reduces friction and helps the hair retain its natural moisture. The cuticle lies flatter and frizz is reduced. Many notice a difference within a few days.
A silk pillowcase is perfect as a simple starting point and for short/fine hair. A silk bonnet completely envelops the hair and is especially good for longer, curly or more textured hair types – as well as for blow-drying, braids and extensions. Many people use both.
Not when the size and fit are right and you tie it softly. Silk reduces friction, so curl patterns and root lift are better preserved than against cotton, which easily presses and frizzes.
No. Satin is a weaving technique and can be made from polyester or silk. Mulberry silk is a natural fiber that breathes and feels extra gentle on hair and skin.
Yes. Frizz and damage are caused by friction and moisture loss – not gender. Short hairstyles are softer and easier to style, and the hairline looks neater in the morning.
Yes. Silk reduces tension at the hair roots, prevents frizz along the edges, and helps protective hairstyles stay neat longer.
Hand wash or machine wash in a laundry bag on a gentle cycle and cold water with a silk-friendly detergent. Avoid bleach and high heat. Air dry flat or lightly draped.
