1. What is Wavy hair?

To learn the differences between wavy hair vs curly hair extensions, we should first look over the definition and surface-level knowledge about these two types first – working from the ground up.

Among four different types of hair patterns out there – straight, wavy, curly and kinky/coily, wavy hair would definitely stand in the middle ground, the transitioning hair patterns between straight and curly hair. And much like what its name might suggest, wavy hair tends to feature S-shape waves, similar to ocean waves, rather than the corkscrew-like shape of the curly hair counterpart:

Overall wave patterns: wavy hair extensions, no matter the type, tend to follow certain rules regarding its patterns – all of their waves mostly follow an S-shape line, flowing from side to side, rather than completing a whole 360 degree rotation. On top of that, generally, these curls often embrace the whole face shape of its user, rather than flowing outward.
Physical appearance: hair buyers using wavy hair extensions might actually notice that the crown area of their hair look tends to appear flatter than the rest. In fact, using wavy hair extensions, its actual volume and wave patterns tend to be more visible and voluminous when reaching the lower lengths, rather than blooming directly at the extension’s attachment point on the roots or at the top head area.

Nowadays, to meet the rising and diversifying demands for hair extensions and other types of enhancement products, manufacturers have introduced numerous variations of wavy hair extensions to the market. For example:

Body wave, Natural wave extensions – best mimic the look of natural 2A wavy hair types: loose, flowing with slight and lightweight patterns.
Round twist, Loose wave extensions – look quite similar and blending with the natural 2B wavy hair types: slightly tighter and more defined waves.
Deep wave, or Water wave – identical to natural 2C wavy hair: tighter, more uniform patterns, with smaller and denser waves.

2. What is Curly hair?

The next thing to learn when comparing wavy hair vs curly hair is the definition and general information about the latter – curly hair extensions.

Unlike wavy or straight hair, curly hair tends to appear much more dramatic and voluminous, with lustrous and defined curls straight from roots to ends, although not as thick and voluminous as the kinky hair variations. For curly hair extensions, their curl patterns are much more visible and defined, with more uniform structure:

Overall curl patterns: despite having some tight waves here and there, on a whole, curly hair patterns tend to lean toward having defined and dense curls – curls that follow a corkscrew-like, springy and spiral formation. Unlike wavy hair patterns, in which the wave formations move side to side, these curls of curly hair tend to perform a whole 360 degree turn, creating rings and spirals of all sizes.
On top of that, as the curls are much tighter and denser than wavy or straight hair, curly hair patterns can shrink drastically, from 10-40% of the strands’ actual length.

Physical appearance: unlike wavy hair extensions, the flow of curly hair patterns tends to be straight down rather than embracing the face shape or growing inward → creating a thick, full and attention-catching hair look. Additionally, throughout the entire hair strands, the curls remain in unison and well-defined, meaning that the overall hair volume would stay the same, even in the crown area of the head.

Circle curly, Water curly – quite similar to the standard 3A hair: the loosest type of curly hair extensions.
Jerry curl – best mimic the look of 3B curly hair type, with tighter and more defined curl patterns
Kinky curl – the closest we got to the natural 3C hair pattern, with the tightest and most densely packed corkscrew-like formation.

Beside these hair pattern choices, hair manufacturers also provide more fashionable, trendy and customer-focused options, such as Body twist, Deep curly, and Spanish curly,… to meet the diverse and ever-changing hair needs in the market.

3. Differences between wavy hair vs curly hair?

On papers, indeed these two types of hair pattern might seem so distinct and easy to tell apart, but in reality, identifying and differentiating wavy hair vs curly hair extension might be a huge challenge, especially when several wavy hair textures might appear similar to curly hair, and vice versa.

Wavy hair extensions

Curly hair extensions

Washing routine

Wavy hair extensions would demand quite frequent hair washes, due to its proneness to buildup and hair grease:

Need to be washed in every 10-12 wears or whenever hair buildup is too visible
Best to be washed with a lightweight, sulfate-free shampoo to avoid dehydration from harsh detergent

→ Focusing most on getting rid of residues, without weighing the strands down.

Curly hair extensions would demand more frequent hair washes, due to its prone to tangle and moisturising needs:

Need to be washed in every 5-7 wears, or whenever as needed – when the hair appears dull, lifeless, or greasy.
Suggested to perform a pre-poo treatment first to avoid moisture loss during the wash.
Using a hydrating and moisturizing shampoo or pre-poo product is a MUST.

→ Focusing on moisturizing and pushing back dryness.

Moisture

Wavy hair’s moisturising and conditioning process also need to be done the right way:

Much like its shampoo, heavy, protein-rich conditioners are highly prohibited to use on wavy extensions – as they can cause more buildup and weigh the waves down.

→ Suggested to use lightweight, mild conditioners only.

As porous and prone to dryness as the curls can get, moisturising is among the must-have maintenance steps for curly hair:

Unlike wavy extensions, high-protein, heavy and nutrient-rich conditioners are the most suitable option for curly hair.
Beside the traditional conditioning step, users should also use leave-ins, creams, and hair mask to add more moisture to the strands

→ Curly hair extensions would need deep moisturizing every 2-3 weeks.

Drying & Styling

Wavy hair extensions are much easier to style, however, its final styling effect can be quicker to fade:

You can either straighten or curl your wavy hair extensions

→ More styling versatility

Prioritizing on lightweight mousse, foam to further elevate the waves.

Curly hair extensions offer less styling versatility:

Curly hair extensions cannot be styled using heat or chemical methods – as the curls can take extreme damage from the high heat and completely break down.
Similarly, to properly style curly hair extensions, using lightweight gel or mousse is highly suggested.
Unlike wavy hair, curly hair extensions cannot be blow-dry → Air-drying is the only proper way to dry your curls

Detangling

Wavy hair is less prone to tangling, hence, easier to detangle:

Wavy hair can be combed both wet or dry.
To detangle wavy hair, use a wide-tooth comb and work from the hair ends

Unlike wavy hair, curls are extremely prone to tangle → more demanding to manage:

Curly hair can only be combed when damp and saturated with conditioner.
Must use fingers for a wide-tooth comb, work slowly to separate the hair clumps

Storage

To properly store wavy hair extensions:

Braid the extension in loose braids, or let them lay flat in their packaging.
Store them in a silk or satin bag, avoid hanging them up to prevent the waves from loosening out over time.

To properly store curly hair extensions:

Store them in loose twists, or put them in a mesh to secure the curls.
Always store them in breathable satin/silk bags, and lightly spray conditioner water, or leave-in before storing

Common maintenance mistake

Some common maintenance mistakes for wavy hair extensions:

Excessive heat styling → causing more open cuticles, subjecting the strands to dehydration and frizz.

Some common maintenance mistakes for curly hair extensions:

Over-brushing, or dry brushing → causing more friction, leading to hair frizz.
Using harsh products with sulfates in them → strip off natural oil and moisture, causing the strands to become more fragile.
