How To Keep Coily Hair Hydrated and Healthy-Looking

The terms curly hair and coily hair are often used interchangeably, but they’re not the same thing. Coily hair—classified on hair texture charts as Type 4A, 4B, or 4C—is the tightest, most fragile, and driest of all natural hair types. It requires a care routine tailored to its unique needs, since products made for looser curls usually won’t cut it.

Ahead, we’ll break down what makes coiled hair unique, how to care for tight coils, and how to enhance your natural texture. You’ll discover our top tips for keeping coils healthy—from careful washing and moisturizing to protective styling and nighttime care—plus tips to achieve a defined, curly afro look. We’ll also highlight some of our favorite coily hair products to add to your routine, from lightweight leave-ins to deep conditioning masks and more.

What Is Coily Hair?

Coily hair—also known as type 4 hair—is a natural hair type characterized by the presence of tight S- or Z-shaped coils. A coily hair type is defined by its density and its significant amount of shrinkage, which can often be 50% or more of its actual length. Because the scalp's natural oils have a harder time traveling down these tight zig-zag patterns, this texture is naturally prone to dryness and fragility.

There are three subtypes of type 4 hair: 4A, 4B, and 4C. Each one has a unique coil pattern that dictates how it behaves and how you should treat it.

4A hair type

Type 4A hair has strands that form springy, S-shaped coils from root to tip. These coils are usually fine in texture and about the diameter of a crochet needle. While this subtype has better moisture retention and more visible definition than 4C hair, it still loves lightweight creams and gels to maintain its bounce.

4B hair type

4B coils boast a defined Z-shape, with the coils bending at sharp angles rather than appearing rounded or spiraled. The strands are densely packed and tend to be coarser, which can contribute to shrinkage. Layering moisture is absolutely essential for this type to maintain its elasticity.

To keep your 4B strands healthy, you might want to read about how to moisturize dry hair. Regular hydration and gentle care are required to prevent breakage and keep your coiled hair looking its best.

4C hair type

4C hair is the coarsest of the type 4 hair subtypes and is incredibly delicate. While there’s a common misconception that 4C hair has no defined pattern, it actually consists of very tight, thin coils that are simply less visible to the naked eye. This subtype experiences the most shrinkage of all natural hair types and requires a high-moisture routine featuring heavy creams and oils. Because of its fragility, this hair type tends to benefit from protective hairstyles, such as locs, twist-outs, and braids.

Coily Hair vs. Curly Hair: What's the Difference?

The main difference between curly and coily hair lies in the diameter of the curl and the shape of the strand. While curly hair consists of looser, bouncy ringlets, coily hair features dense, tight spirals that form a Z-shape or a very tight S-shape.

All coils are curls, but not all curls are coils. This distinction is vital because the tight structure of coily hair makes it much harder for natural scalp oils to lubricate the hair shaft compared to looser curls. This is why a coiled hair routine must focus much more heavily on manual hydration than a standard curly routine.

How To Care For Coily Hair

Caring for coiled hair requires a gentle hand and a routine that prioritizes moisture, low manipulation, and protection. Ideally, you should wash your hair once or twice a week and incorporate a deep conditioning treatment every seven days to maintain strength.

Keep reading for eight of our top tips to help your coils look and feel their best.

1. Use a hydrating shampoo and conditioner

The curlier the hair, the more difficult it is for oil to travel from the scalp down the strands, which is why tight coily hair is often dry and highly porous. Using hydrating products can help your strands retain moisture and minimize the chance of breakage when you style your strands.

On wash day, cleanse your hair with the L’Oréal Paris EverPure Sulfate-Free Moisture Shampoo and the L’Oréal Paris EverPure Sulfate-Free Moisture Conditioner (pictured below). The duo gently cleanses away excess oil and debris while nourishing parched strands for hydrated, healthy-looking hair. For added hydration, leave the conditioner in for a few minutes before rinsing with lukewarm water.

If your hair is damaged, consider using the L’Oréal Paris EverPure Sulfate-Free Bond Repair+ Shampoo and L’Oréal Paris EverPure Sulfate-Free Bond Repair+ Conditioner instead. The Bond + Amino Acid Complex helps strengthen weak, brittle hair from the inside out to help promote resilient, healthy-looking strands—no matter your texture.

2. Detangle with care

Coils are beautiful and delicate, and they require gentle handling. You should never be too rough while detangling, as this can cause breakage and split ends. Instead, use a wide-tooth comb to carefully work out knots while your hair is still wet, starting from the ends and gradually working your way upward.

For added assistance, spritz your damp mane with the L’Oréal Paris EverPure Sulfate-Free Moisture 21-in-1 Leave-In Conditioner before detangling. This versatile spray provides 21 different benefits, including heat protection and intense priming, to help your comb glide through knots without resistance.

3. Embrace the LOC method

Type 4 hair is delicate and can get dry, which often causes your hairstyle to frizz. That’s where the LOC method can come in handy. The technique involves applying a leave-in conditioner (L), then layering on a hair oil (O), and finishing with a styling cream (C) to help retain moisture and keep frizz at bay.

After applying your leave-in conditioner and detangling your strands, work a small amount of the L’Oréal Paris EverPure Bond Repair+ Hair Oil-in-Serum throughout your coils. The lightweight formula with castor oil helps strengthen fragile strands, boosts shine, and offers protection against temperatures up to 450 degrees Fahrenheit (a must if you plan on heat-styling your hair).

Then, finish with a hydrating cream to help lock in moisture and give your coils a bouncy, defined finish. We’re partial to the L’Oréal Paris Elvive Dream Lengths Curls Leave-in Conditioner (pictured below), which is designed specifically for textured hair. Work it throughout your mane from root to tip, then dry as usual for unbeatable coily definition.

4. Sleep on silk

Sleeping on a silk or satin pillowcase is a must if you have delicate, coily hair. These fabrics are slippery and create less friction against your strands than a cotton or linen pillowcase might. By keeping friction to a minimum, you will experience less breakage and frizz come sunrise. Plus, silk and satin are less absorbent than cotton, which means they are less likely to soak up all the moisture from the coily hair products you use at night.

If you don’t want to shell out on a new pillowcase, a silk or satin bonnet works equally well to protect your strands while you snooze.

5. Get regular trims

The ends of your coily hair are the most prone to breakage. Getting regular trims (generally, every six to eight weeks) can help prevent split ends from forming. You should book an appointment with a professional hairstylist who is well-versed in coily cuts to trim your ends and discuss the best trimming schedule for you.

6. Don’t neglect your scalp

Those with coily hair typically use a lot of styling products to keep their hair looking its best, and over time, those products can accumulate on their scalp and roots. If you’re dealing with buildup, try adding a clarifying scalp treatment, such as the L’Oréal Paris Elvive Hyaluron + Pure Oil Erasing Serum, to your routine once or twice a week. This salicylic acid-infused formula helps minimize excess oils and remove scalp residue while infusing the hair with up to 72 hours of hydration. You apply it directly to the scalp, let it work its magic for ten minutes, and then proceed with your shampoo.

7. Avoid shampooing too frequently

Those with finer, straighter hair often need to shampoo several times per week in order to keep greasiness at bay. But coily hair is different, and those with this hair type can typically go several days or more without shampooing. Spacing out how often you shampoo can also help prevent your hair from drying out.

If you’re unsure when to schedule wash day each week, we suggest consulting a hairstylist well-versed in coily hair care.

8. Choose the right hairstyle for coily hair

There are countless coily hair styles that can complement and help protect your natural texture. Whether you're gearing up for a special event or want to switch up your everyday look, here are a few of the best options that will keep you looking fabulous.

• Protective styles: Protective hairstyles like box braids, bantu knots, and two-strand twists can help shield your delicate strands from damage. They are designed to last several weeks, making your morning routine effortless.
• Wash-and-go: Perfect if you want defined coils. Apply gel and mousse products using techniques like raking and shingling to ensure even distribution.
• Afro: Rock your afro to fully embrace your coily texture. After adding your moisturizing products using the LOC method, you can air-dry or use a hair pick to loosen your coils for a fuller-looking curly afro look.
• Updos: Buns and updos are classic styles for coily hair. You can gather your hair into a ponytail and twist it into your desired shape, securing it with bobby pins.
• Frohawk: This bold and edgy hairstyle highlights the natural beauty of your coils. Part your hair down the center and pin the sides back to create a striking contrast.

How To Keep Coily Hair Moisturized Between Wash Days

Keeping your hair hydrated between washes is key to maintaining health. A daily refresh routine involving a light mist of water, a leave-in conditioner, and a sealing oil can work wonders. For the latter, try the aforementioned L’Oréal Paris EverPure Bond Repair+ Hair Oil-in-Serum—the leave-in’s non-greasy texture is perfect for restoring moisture to dry coils.

Another great technique is the pineapple method, where you gather your hair loosely at the very top of your head to prevent curls from being crushed while you sleep. Lastly, when possible, avoid drying stressors like excessive heat, chlorine, or sun exposure, which can dehydrate your strands and leave your coils limp and frizzy rather than soft and springy.
