Curly hair has a reputation for being difficult, but most of the difficulty comes from treating it like straight hair. The routine that works on straight hair — wash every day, brush it dry, rub it with a towel — will leave curls dry, frizzy and shapeless.
Curls are not a problem to fix — just a different structure with different needs. The routine is simple: wash less, moisturise more, handle gently, and apply products while the hair is still wet.
Why curly hair needs a different routine
It starts with the shape of the strand. On straight hair, scalp oils slide easily down the shaft and keep the whole length moisturised. On curly hair, they must travel down a twisting, corkscrew-shaped strand — and much of them never reach the ends. As a Cleveland Clinic dermatologist puts it, the oils struggle to travel down the curl, so the ends tend to be drier.
The American Academy of Dermatology (AAD) describes curly hair as drier than other hair types for the same reason. That dryness is why curls frizz, tangle and break more easily — and why washing them like straight hair makes things worse.
Know your curl type — but do not overthink it
Curls are usually described on a scale from 2A to 4C: type 2 is wavy, type 3 is curly with springy ringlets, and type 4 is coily with tight zig-zag coils. Your type mainly helps you choose product weight — looser waves (2A–3A) suit lighter leave-ins and creams, while tighter curls and coils (3C–4C) usually need richer creams and oils. Most people have more than one pattern on their head, which is completely normal.
1. Wash less often — and wash the scalp, not the lengths
The single biggest change most curly-haired people can make is washing less. The AAD warns that washing curly hair too often leaves it dry, frizzy and hard to manage. Thick, curly hair does not need washing daily, or even weekly: the AAD's guidance is to wash at least every two to three weeks for scalp and hair health, and more often only when your scalp needs it.
Start gradually: try every three or four days, then stretch the gap. When you do wash, use a moisturising, ideally sulphate-free shampoo made for curly hair — sulphates are strong cleansers that strip moisture. Work it into the scalp, not the lengths: the rinse is enough to clean the rest.
Tip: On non-wash days, wear a shower cap in the shower. It keeps your curls dry, so wash day stretches further without your hair looking flat.
2. Condition every time — roots to ends
If there is one non-negotiable rule for curly hair, it is this: condition every single time you wash. The AAD advises applying a thick conditioner through the full length of curly hair, because the whole strand is thirsty, not just the tips. Leave it on for a minute or two, then rinse, and follow with a leave-in conditioner or a few drops of oil to seal the moisture in.
Look for conditioners with argan oil, glycerin or a fatty alcohol such as cetyl or stearyl alcohol. If your hair is very dry, add a deep conditioner once a week, left on for ten to twenty minutes under a shower cap.
3. Detangle wet, never dry
Brushing dry curls is the fastest way to destroy them. A brush pulls the curl pattern apart, creating the puffy triangle of frizz so many curly-haired people know. The AAD's rule is simple: detangle wet, never dry.
Soak your hair, apply a leave-in conditioner, then work through knots in sections with your fingers, a wide-tooth comb or a brush designed for curly hair. Start at the ends and work up towards the roots to keep breakage down. For thick, curly hair, comb in the shower before rinsing out your conditioner, when the hair has maximum slip.
Warning: Never detangle dry curls with a regular brush, and never yank a comb through from root to tip. Both snap hairs and turn defined curls into frizz.
4. Style on soaking wet hair — the LCO method
Curl products work best on wet hair, not dry. Apply styling products to soaking wet or very damp hair, so the curl pattern sets as the hair dries.
A simple layering method many curl specialists use is called LCO — liquid, cream, oil. First, a liquid: a water-based leave-in conditioner on soaking wet hair. Then a cream: a lightweight curl cream, smoothed or scrunched through in sections. Then an oil: just a few drops, to seal everything in. Use less than you think you need at first — too much product weighs curls down and causes buildup. Scrunch products in with an upward motion, cupping the curls towards your scalp, rather than raking them through: raking separates curls, scrunching helps them clump into defined ringlets. Then leave your hair alone while it dries.
5. Dry gently: a T-shirt, plopping, or a diffuser
A regular terry-cloth towel is rough on curls. Rubbing wet hair with one roughs up the cuticle and that roughness shows up as frizz. Instead, gently squeeze water out with an old cotton T-shirt or a microfibre towel, scrunching upwards in sections. No rubbing.
Plopping is a popular variation: lay the T-shirt flat, tip your wet curls onto it, wrap it up around your head, and leave it for fifteen to twenty minutes. It absorbs water while keeping the curl pattern intact. If you use a hairdryer, attach a diffuser on a low or medium heat setting — it spreads the airflow so it dries curls without blasting them apart. Apply a heat protectant first, and stop at about 80% dry.
6. Protect your curls while you sleep
You can spend an hour defining your curls and lose them to eight hours on a pillow. Cotton pillowcases are the main culprit: the rough fibres catch on curls, rough up the cuticle and absorb moisture as you move.
The fix is cheap. A satin or silk pillowcase lets curls slide instead of snagging, and it does not drink up their moisture. People with longer hair often use the "pineapple" method: gather the curls loosely on top of the head with a soft scrunchie, so they are not crushed flat overnight. Make sure your hair is completely dry before bed, and keep every tie, twist or braid loose.
7. Clarify when you notice buildup
Leave-in conditioners, gels, curl creams and oils all leave residue behind, especially when several products are layered together. Over time, that buildup can make curls feel coated, look dull or lose their usual bounce — and no amount of extra conditioner will fix it, because the residue is sitting on top of the hair.
When that happens, use a clarifying shampoo: a stronger cleanser designed to lift residue that an everyday shampoo may not fully remove. Follow it with a good conditioner, since clarifying shampoos are drying by design. If your hair is coloured, very dry or chemically treated, choose a formula suitable for your hair and avoid clarifying more often than you need to — once every few weeks is enough for most people.
A simple curly hair routine to start with
Wash day
- Wet hair thoroughly. Shampoo the scalp with a moisturising, sulphate-free shampoo; wash in sections if your hair is long or thick.
- Apply a thick conditioner through the full length. Detangle in the shower with a wide-tooth comb, ends first, before rinsing.
- Leave-in conditioner on soaking wet hair, then curl cream, then a few drops of oil.
- Scrunch upwards. Dry with a T-shirt or plop for fifteen to twenty minutes, then air-dry or diffuse on low heat. Do not touch the curls until they are dry.
Between wash days
- Sleep on a satin or silk pillowcase, or in a bonnet or loose pineapple, with hair fully dry.
- Refresh in the morning: mist the curls lightly with water, scrunch, and smooth a little leave-in or curl cream over the frizzy spots only.
- Wear a shower cap on non-wash days; deep condition weekly.
Mistakes that flatten your curls
| Mistake | What happens | Do this instead |
|---|
| Washing every day | Stripped moisture, dry frizzy curls | Wash when your scalp needs it |
| Brushing dry curls | Pattern pulled apart into frizz | Detangle wet with a wide-tooth comb |
| Rubbing with a terry towel | Roughened cuticle, more frizz | Squeeze gently with a T-shirt |
| Styling on dry hair | Products sit on top | Apply products to wet hair |
| Touching curls while drying | Pattern breaks, frizz forms | Leave them alone until dry |
| Sleeping on cotton | Flattened, tangled curls | Satin pillowcase or bonnet |
The honest summary
Good curly hair care is not complicated. It is a short list of habits that work with the structure of curly hair instead of against it: wash less often and only the scalp, condition the full length every time, detangle wet with a wide-tooth comb, style on soaking wet hair, dry gently without touching, and protect your curls at night on satin.
Start with the three changes that make the biggest difference — wash less, condition properly, stop brushing dry curls — and add the rest one at a time. Give it a month. Your curls will tell you the rest.
How often should I wash curly hair?
Less often than straight hair. The American Academy of Dermatology says thick, curly hair does not need washing daily or even weekly, and recommends washing at least every two to three weeks for scalp health. In practice, most people wash once or twice a week, or when the scalp feels itchy or weighed down.
Why is my curly hair always frizzy?
Frizz usually comes from dryness plus friction. Curly hair is naturally drier because scalp oils cannot travel easily down the twisted strand, and brushing dry curls, rubbing with a terry towel, or touching curls while they dry all rough up the cuticle. Condition the full length every wash, detangle only when wet, and leave curls alone until dry.
What is the LCO method for curly hair?
LCO stands for liquid, cream, oil — a layering order for styling products on soaking wet hair. First a liquid (a water-based leave-in conditioner), then a cream (a lightweight curl cream), then an oil (a few drops to seal moisture in). Each layer locks the previous one in, keeping curls moisturised and defined for longer.
Can I brush my curly hair at all?
Only when it is wet and coated with conditioner — in the shower, with a wide-tooth comb or a brush made for curly hair, working from the ends up. Brushing dry curls pulls the pattern apart and creates frizz. Between wash days, use damp hands and a little leave-in conditioner instead.
