Best shampoo for curly hair: how to choose the right one
Curly hair needs different care from straight hair. The best shampoo for curls isn't the most popular brand in the shop, but the shampoo with the right ingredients for your curl type.
In this guide you'll read what to look for when choosing a shampoo for curly hair, and why a sulfate-free, solid shampoo bar is often the strongest choice.
Why curly hair needs a different shampoo
Curly hair has a winding structure. As a result, the natural sebum from your scalp reaches the lengths and ends less easily than with straight hair. The consequence: curls are naturally drier and more prone to frizz and breakage.
A regular shampoo, with strongly cleansing agents, only makes this problem worse. Caring for curly hair therefore starts with a mild, hydrating cleanser instead of a harsh shampoo that dries your hair out further.
What should you look for in a shampoo for curls?
Not every shampoo for curly hair is suitable for your hair type. Use the checklist below to compare shampoos and decide which suits your curls.
Sulfate-free and gently cleansing
Sulfates such as SLS and SLES are powerful cleansing agents that thoroughly remove dirt and product residue. For curls, that's a drawback: sulfates also strip away the natural oils your curls need to stay supple.
A sulfate-free or mild cleanser holds moisture in your hair better. "Shampoo with or without sulfates" is therefore one of the most frequently asked questions from people with curls, and not without reason.
Hydration and natural ingredients
Besides gentle cleansing, curly hair needs ingredients that hold moisture. Think of coconut oil and argan oil, which nourish the hair shaft, shea butter, which forms a protective layer, and glycerine, which attracts and binds moisture.
These ingredients don't all work the same way. Finer curls often benefit from lighter oils, while thicker or drier curls benefit from richer, nourishing formulas.
Without silicones and parabens (CG-friendly)
Many people with curls avoid silicones and parabens. Silicones coat the hair with a layer that looks smooth at first, but builds up over time and weighs curls down. Parabens, in turn, are known as a preservative that many curly-haired people would rather steer clear of.
This fits with the Curly Girl Method, a haircare routine that avoids precisely these ingredients. A CG-friendly shampoo helps you keep your natural curl pattern instead of flattening it.
Why a shampoo bar is the best choice for curls
If you put all the criteria above side by side, you often end up with a surprising answer: the solid shampoo bar. No hard sell, just logic.
A shampoo bar has a concentrated formula without added water, which allows the cleansing ingredients to stay gentle and effective. Most bars also come without plastic packaging, which makes them as good for your curls as for the planet.
Handy for travel, economical to use and gentle enough to protect your curl pattern instead of disrupting it. For haircare for curls that's exactly what you're looking for.
How to wash your curls with a shampoo bar
Good news: washing with a shampoo bar is no more complicated than with a bottle. Follow these steps for the best result.
- Wet your hair thoroughly. Use lukewarm water, not hot, to prevent dryness.
- Rub or lather up the bar. Rub the bar directly over your scalp, or lather it up in your hands first if you have a sensitive scalp.
- Massage in gently. Work the lather through your scalp and lengths with your fingertips, without scrubbing.
- Rinse thoroughly. Make sure no product residue is left behind, and finish with a nourishing conditioner on your lengths and ends.
Don't wash curly hair too often: once or twice a week is enough for most curl types to stay clean without rinsing away the natural oils.
