How to Curl Your Hair with Products | The No-Heat Routine That Works

For the full breakdown, see our best Drugstore Curling Hair Products guide.

Most curling methods center on a hot iron, but the healthiest way to curl your hair is to enhance what’s already there. The process comes down to layering the right products on soaking-wet hair, then leaving your hair alone until it’s completely dry. When you let curls form without touching them, they set in place and hold their shape for days.

What You Need to Start Curling Hair with Products

The right product stack makes the difference between defined curls and frizz. You will need a cleanser, a conditioner, a leave-in treatment, and a styling product such as a gel, cream, or mousse. Each one builds on the last to hold the curl pattern.

Look for collections designed around curly hair, like L’Oréal Professionnel’s Curl Expression line. It includes a Moisture Shampoo, an Anti-Buildup Cleansing Jelly Shampoo, an Intensive Moisturizer Mask, and a 10-In-1 Cream-In-Mousse.

If you already own a favorite gel or mousse, that works too. The method matters more than the brand.

The Step-by-Step Process for Defined Curls

This routine works because each step prepares the hair for the next one. Timing matters, so follow the order closely.

1. Cleanse your hair. Wash with a sulfate-free shampoo if your curls are dry, or use a clarifying shampoo once every couple of weeks to remove product buildup.
2. Condition thoroughly. Apply a rich conditioner or mask from mid-length to ends, then rinse with cool water to help seal the cuticle.
3. Apply leave-in to soaking-wet hair. While your hair is still dripping, work a leave-in cream or jelly through it. This locks in moisture before any styling product goes on.
4. Layer your styling product. Emulsify a gel, cream, or mousse between your palms, then scrunch it into your hair in sections. Do not rake your fingers through — that breaks up the curl clumps.
5. Dry without touching. Let your hair air-dry completely, or use a diffuser on low heat if you are short on time. Avoid touching or brushing it while it dries, since that creates frizz.
6. Scrunch out the cast. Once fully dry, gently scrunch your hair with clean hands to break the stiff product cast. Your curls will soften and move naturally.

This routine is safe for color-treated and heat-damaged hair because it skips the hot tools entirely. Redken’s curly hair styling line offers mousses and creams that work the same way if you prefer a different formula.

Product Layering Tips That Actually Matter

A common mistake is applying styling products to towel-dried hair. That traps water unevenly and leaves some strands with too much product and others with none. Working on soaking-wet hair ensures even distribution.

If your curls fall flat by midday, you are likely using too heavy a cream. Swap to a mousse or a lightweight jelly instead. If your hair looks crunchy, you are likely using too much product or you skipped the final scrunch. The cast-breaking step is what separates glassy curls from stiff ones.

For those with fine hair, apply products in smaller amounts and focus on the ends rather than the roots. Coarse or thick hair can handle a heavier cream plus a gel to hold the shape.

Safety Note on Heated Hair Tools

Air-drying is the safest route, but if you use a curling iron or diffuser, check that your device meets basic electrical safety standards. The IEC 60335-2-23 standard covers household hair-care appliances like curling irons, hair straighteners, and hairdryers rated up to 250 V.

That product did not meet the Electrical Equipment (Safety) Regulations 2016. Stick to reputable brands and avoid unfamiliar, unbranded heated tools.

FAQs

Will my curls last overnight? Yes, if you protect them before sleeping. Wrap your hair in a silk scarf or use a satin pillowcase to reduce friction. In the morning, refresh with a little water and a small amount of leave-in cream. Avoid re-drying with heat, since that can flatten the curl pattern.

Can I use these products on straight hair? The products will give texture and light wave, but they will not create tight curls on naturally straight hair without heat styling. A mousse or curl-defining cream can add body, however, and the scrunching motion helps encourage whatever natural wave you have.

How often should I wash curly hair? Most curly hair does best with washing two to three times per week. Co-washing with conditioner only is fine on off days. Build-up from heavy creams and gels means you should use a clarifying shampoo every two to four weeks to keep curls springy.
