Curls usually drop for one of four reasons: moisture left in the hair, sections that were too big, curls touched before they cooled, or humidity. Fix those and your curls hold far longer — on any curling tool.

Why do curls fall out?
| Problem | What's happening | Fix |
|---|---|---|
| Curls drop within an hour | Hair wasn't fully dry, or curls were brushed while warm | Dry completely; let every curl cool before touching |
| Curls are loose from the start | Sections too big for the tool | Use smaller sections — split thick ones |
| Curls go frizzy, not flat | Humidity is swelling the hair | Smoothing prep and a humidity-resistant finishing spray |
| Only the ends hold | Heavy conditioner or oil near the roots | Keep heavier products to the ends; use a lighter prep |
| Fine hair won't hold at all | Hair is too soft and slippery | Light texturising prep, small sections, cool-pin method |
The prep-curl-cool-set routine
1. Prep
Start with completely dry hair. If you wash in the morning, dry it fully — even slight dampness at the roots stops curls setting. Apply heat protectant; if your hair is fine or freshly washed and silky, a light texturising spray gives curls something to hold on to.
2. Curl in small sections
This is the single biggest factor. Small sections heat through evenly and set into tighter shapes that relax into soft curls, rather than loose curls that relax into nothing. On an automatic curler, if a section feels thick between your fingers, split it.

Hair sets as it cools. Let each curl drop into your palm and leave it, or roll it back up and hold it with a clip until it is completely cool (the 'cool-pin' method). This is the professional trick most at-home routines skip.
4. Set
Once everything is cool, separate curls gently with your fingers — not a brush — then mist with a flexible-hold hairspray from a distance. Flip your head and spray underneath for volume that lasts.
How to keep curls in humidity
- Smooth the hair cuticle first: a light smoothing product on the mid-lengths and ends before heat.
- Use slightly smaller sections than usual.
- Finish with a humidity-resistant spray.
- Pack a mini straightener to smooth frizzy front pieces later in the day — see our touch-up method.
- Accept a softer wave by evening — and plan your look around it.
Curls for fine hair
Fine hair holds curls less easily because each strand has less structure. The fixes: lower heat with smaller sections (rather than higher heat), a light texture spray, the cool-pin method, and refreshing only the front sections midday rather than redoing everything.

Frequently asked questions
Why won't my hair hold a curl?
The most common causes are damp hair, sections that are too big, touching curls before they cool, and heavy products. Fine hair also needs smaller sections and a light texture spray.
Does hairspray before curling help?
A light, heat-safe setting or texture spray can help some hair types. Use products designed for use before heat styling and follow their instructions.
Should I curl clean or dirty hair?
Second-day hair often holds curls better than freshly washed, silky hair. If you curl on wash day, a texture spray helps.
