If your curls usually drop by breakfast but your hair hates repeated heat, a Curlformers Spiral Curls Kit review is most useful when it answers two questions: can the kit create a neat spiral without tongs, and is the process worth the faff?

Quick verdict: it can produce defined, springy curls on the right hair, with a smoother finish than many overnight foam or fabric methods. The trade-off is technique. You need properly sectioned, detangled, slightly damp hair, and the pulling motion through the curler can feel fiddly until you get the rhythm. It is not the laziest heatless method, but it is one of the more precise ones.

Product overview

The Curlformers Spiral Curls Kit is a heatless curling system built around spiral-shaped curlers and a styling hook. Instead of wrapping hair around a rod, you pull small sections through each curler so the hair dries in a spiral formation. That makes the result more uniform than sock curls or robe-belt curls, but also more dependent on careful sectioning.

The appeal is obvious for anyone trying to reduce hot-tool use: you get a structured curl pattern without a curling wand. For breakage-prone lengths, colour-treated hair, or hair that feels rough after frequent heat styling, that matters. The kit is also useful if you like a consistent finish rather than the softer, more random bend you get from many fabric curlers.

Before adding it to your basket, check the exact kit version carefully. Curlformer-style kits can vary by curler length, curl width, pack count and included hook pieces, and those details affect whether the kit will suit a bob, shoulder-length hair, long layers or very dense hair. In the UK, also check the retailer’s returns policy before opening hygiene-sensitive hair accessories.

Pros and cons

Pros

Creates a more controlled spiral shape than many soft heatless curlers.
Useful for reducing reliance on curling wands and hot rollers.
Can give a polished finish when sections are neat and hair is properly prepped.
Reusable, so it makes sense for people who curl their hair regularly.
Works well for layered hair when you choose an appropriate curler length and section size.

Cons

The hook technique has a learning curve, especially at the back of the head.
It can tug if hair is knotty, too large a section is used, or the hook is rushed.
Very thick hair may need more curlers than some kits provide.
It is not as comfortable for sleeping as softer satin rods or fabric wraps.
Results depend heavily on hair being dry before removal.

Performance in real use

Ease of use

The Curlformers Spiral Curls Kit is straightforward in concept but not instant in practice. The best results come from small, clean sections. If you try to pull too much hair through one curler, the hook can drag, the curl can dry unevenly, and the finished spiral may look stretched rather than bouncy.

For first use, expect a slower styling session. Working from the lower layers upwards helps, and clipping the top section out of the way makes the back easier to manage. If you already struggle with knotting, read our guide to detangling before heatless styling before using any hook-based curler, because smooth prep makes a big difference to comfort and finish.

Comfort and wearability

This is where the kit divides opinion. For daytime setting while you work from home, do skincare, or get ready slowly, it is easy enough to wear. For overnight styling, it is more personal. The curlers are not as squashy as satin rods, so side sleepers may find them awkward around the crown and nape.

If you want a heatless method mainly for sleeping, the Curlformers Spiral Curls Kit is less cushioned than a fabric wrap. If you can set your hair earlier in the evening and remove the curlers before bed, comfort becomes much less of an issue.

Curl finish

The finish is the main reason to consider this kit. It can create glossy, separated spirals with a very intentional shape. On naturally straight or wavy hair, the result is more ringlet-like than beachy. On curly hair, it can help standardise an uneven curl pattern, although it will not replace a full wash-day routine if your hair needs moisture, hold and frizz control.

Fine hair can look beautifully full, but only if the sections are not overloaded with product. Medium hair is often the sweet spot: enough body to hold the spiral, but not so much density that you run out of curlers. Thick hair can work well, but you may need patience, smaller sections and enough curlers to cover the whole head. For extra hold strategies, especially if your hair is dense or heavy, our guide on getting heatless curls to hold in thick hair is a useful next step.

Frizz control

Frizz usually comes from three things with this kit: rough detangling, hair that is too wet, or rushing removal. The sweet spot is damp rather than dripping hair. A light leave-in spray or a small amount of smoothing product can help, but heavy creams may slow drying and leave the spiral limp.

When removing the curlers, do not pull straight down aggressively. Let each curler relax open and slide it away from the curl. Then separate curls with fingers rather than brushing immediately. If you want more volume at the roots, shake gently at the scalp once the curl is fully dry.

Durability and maintenance

The Curlformers Spiral Curls Kit feels like a reusable styling tool rather than a disposable gimmick, but longevity depends on how you handle the sleeves and hook. Forcing oversized sections through the curler can strain the tool and your hair. Product residue can also build up over time, so wipe the curlers clean when needed and allow them to air dry fully before storing.

Value for money

Value depends less on the headline price and more on whether the kit matches your hair length and density. If one pack is enough for your head and you like neat spiral curls, it can earn its place quickly. If you have very thick or long hair and need extra curlers, the overall spend may be closer to a more premium heatless routine. Check the pack contents carefully rather than assuming every Curlformers Spiral Curls Kit offers the same coverage.

Who it’s best for / who should skip it

Best for

Straight, wavy or lightly curly hair that needs a more defined curl pattern.
Medium-density hair where one suitable kit can cover the head comfortably.
People who want polished spirals rather than soft, undone waves.
Anyone reducing heat damage from regular wand styling.
Hair that is long enough to sit securely inside the curler length chosen.

Skip it if

You want the softest possible overnight curler for sleeping.
Your hair tangles very easily and you dislike hook-based styling.
You prefer loose bends, brushed-out waves or a barely styled finish.
You have very dense hair and do not want to buy enough curlers to section properly.
You need a five-minute styling method with no learning curve.

Alternatives

If you like the idea of heatless curls but want a softer overnight option, the Kitsch Satin Heatless Curling Set is the more sleep-friendly direction. It tends to create looser, softer curls rather than tight spirals, so the choice is really about finish: Curlformers for definition, satin rods for comfort and ease. We have a fuller breakdown in our Kitsch Satin Heatless Curling Set review.

Velcro rollers are another route if your priority is root lift and bouncy ends rather than spiral curls. They are not a direct replacement for the Curlformers Spiral Curls Kit, but they can suit shorter layers and blowout-style volume better.

Questions people ask

Can you sleep in the Curlformers Spiral Curls Kit?

You can, but comfort depends on your sleep position and tolerance for firmer curlers. Many people will find it better for evening setting rather than a full night’s sleep.

Does the Curlformers Spiral Curls Kit work on thick hair?

Yes, but only with small sections and enough curlers. Very thick hair may need more than one pack, depending on the kit size and your desired curl density.

Should hair be wet or dry before using it?

Slightly damp hair is usually the most practical starting point. Very wet hair can take too long to dry, while fully dry hair may not set well without extra styling product.

Will it damage hair?

It avoids direct heat, which is a major benefit, but poor technique can still cause tugging. Detangle first, use smaller sections and never force the hook through knots.

What curl type does it create?

Expect defined spiral curls rather than relaxed waves. The exact result depends on the curler width, section size, hair length and how completely the hair dries before removal.

Verdict + score

The Curlformers Spiral Curls Kit is worth it if you want structured, heatless spirals and you are prepared to spend time on sectioning. It is more precise than most soft curlers, better for definition than casual waves, and a sensible option for reducing hot-tool exposure. It is not the easiest or cosiest method, and very thick hair needs careful kit sizing, but the results can look impressively polished once you master the hook technique. Score: 8.4/10.
