Cranial Helmet Therapy for Babies: Head Shaping Helmet Guide | CranioWell

Cranial helmet therapy corrects head shape differences in babies with a custom-made helmet while the skull is still growing quickly. It is also called a cranial remolding helmet, cranial orthosis, flat head helmet or simply a baby helmet. This guide explains what the helmet does, which babies need it and at what age, how long treatment takes and how care works at CranioWell.

Short answer: A cranial helmet is a lightweight helmet made for one baby from a 3D scan of the head. It does not squeeze the head; it limits growth at prominent areas and leaves space at flat areas so growth fills them. It is used for moderate and severe plagiocephaly, brachycephaly and positional scaphocephaly. The most effective period is usually 4–7 months of age, and the helmet is worn 23 hours a day.

• What for? Plagiocephaly (asymmetric head), brachycephaly (flat head), positional scaphocephaly.
• At what age? Most effective at 4–7 months; the effect decreases after 12 months.
• How many hours a day? 23 hours; removed for bathing.
• Where is it fitted? The HKM Pro helmet is fitted only at CranioWell Orthotics & Prosthetics Centers.

What is a cranial helmet?

“Cranial” means related to the skull. The medical name of the device is a cranial orthosis. When parents say “head shaping helmet”, “flat head helmet” or “baby head helmet”, they mean the same treatment.

A cranial helmet is not an off-the-shelf product. Each baby’s head is measured separately, and the helmet is designed and produced for that head shape. The outer shell is light; the inner surface is a soft lining that touches the baby’s skin.

Why do babies wear a helmet?

A baby’s skull is soft and flexible in the first months so it can adapt to the fast-growing brain. When a baby lies on the same side for long periods, that part of the head can flatten. Mild cases often improve with repositioning and tummy time. In moderate and severe cases that do not improve on their own, a helmet is used to guide head growth during this period.

Which conditions is a cranial helmet used for?

• Plagiocephaly (asymmetric head): One-sided flattening at the back or side of the head. More: what is plagiocephaly?
• Brachycephaly (flat head): The whole back of the head is flat and the head widens to the sides. More: what is brachycephaly?
• Positional scaphocephaly: A long, narrow head shape, seen more often in premature babies. More: what is scaphocephaly?
• After craniosynostosis surgery: When skull sutures close too early, treatment is surgical; the surgeon may recommend a helmet after the operation. More: what is craniosynostosis?

How does a helmet correct a baby’s head shape?

The helmet does not squeeze or press the head. It contacts the prominent areas to limit growth there and leaves space over the flat areas. As the head grows, that space fills and the head reaches a more symmetrical shape.

The inner surface of the helmet is adjusted as the head grows. Even if the baby keeps resting the head on one side, the helmet prevents further pressure on the flat area.

At what age should helmet therapy start?

Head growth is fastest in the first months, and the helmet works by guiding this growth. The most effective period is therefore usually 4–7 months of age. Before 4 months, most babies first try repositioning, tummy time and physiotherapy if needed.

After 12 months, head growth slows down and the helmet’s effect decreases. For older babies, suitability is decided with a 3D measurement and assessment. More: when should helmet therapy start? and is helmet therapy possible after age one?

How do you know if your baby needs a helmet?

The decision is not made from a single photo or by eye. A doctor first examines the baby and rules out other conditions such as craniosynostosis. The head shape is then measured with a 3D scan, and the diagonal difference and asymmetry index are calculated. Age, severity and response to repositioning are assessed together. Not every baby is a candidate for a helmet.

How many hours a day is a baby helmet worn?

The helmet is worn 23 hours a day. It is removed for bathing and skin care; the baby keeps it on while sleeping, playing and feeding. Shorter wear slows correction. In the first days, wear time is increased gradually so the baby can adapt.

• First week: Most babies get used to the helmet within a few days.
• Cleaning: The helmet is cleaned every day and the skin is checked.
• Skin: Mild redness can occur; redness that does not fade or any sore is assessed at the follow-up visit. More: risks of cranial helmet use.

How long does helmet therapy take?

Duration depends on the baby’s age at the start and the severity of the head shape difference. When treatment starts early, it usually takes three to four months; when it starts later, growth is slower and treatment may take longer. Treatment today is usually completed with a single helmet.

How does helmet therapy work at CranioWell?

1. Pre-assessment: Send photos of your baby’s head with the pre-assessment form or call us.
2. 3D scan: At the CranioWell Orthotics & Prosthetics Center, your baby’s head is measured in seconds with a radiation-free, contact-free 3D scanner.
3. Assessment: The results are shown to you; we explain whether a helmet is needed and what the alternatives are.
4. Production and fitting: If a helmet is needed, it is made for your baby and fitted at our center; use and care are explained.
5. Follow-up: The helmet is adjusted at regular visits and progress is measured with 3D scans.

The HKM Pro head shaping helmet is fitted only at CranioWell Orthotics & Prosthetics Centers. Product details: HKM Pro baby helmet therapy.

• Made in Türkiye: The HKM Pro helmet was developed through R&D at Hacettepe Teknokent.
• Registration: Registered with the Turkish Patent Office; a medical device registered in ÜTS and EUDAMED.
• 3D scanning: Measurement and follow-up use radiation-free 3D scan data instead of a tape measure.

Where is helmet therapy done?

Diagnosis and referral are made by a physician; measurement, production, fitting and follow-up are carried out at the orthotics and prosthetics center. At CranioWell the helmet is fitted only at our own centers in Ankara, with an İstanbul Ataşehir branch opening soon.

Cranial helmet cost and insurance

The cost becomes clear after the 3D scan and pre-assessment. There is no different fee by severity; treatment is usually completed with one helmet, so one fee is paid. In Türkiye, SGK does not currently cover the helmet fee; some private health insurance policies may. For price information, call us or fill in the pre-assessment form.

Frequently asked questions

Does a cranial helmet hurt or harm the baby?

The helmet does not squeeze the head or restrict brain growth; it guides growth. Most babies get used to it within a few days. The most common issues are sweating and mild skin redness, managed with daily cleaning and follow-up visits.

Is a head shaping helmet always necessary?

No. Most mild head shape differences improve with repositioning and tummy time. A helmet is recommended for moderate and severe cases that do not improve on their own, together with a doctor’s assessment and a 3D measurement.

Can my baby sleep in the helmet?

Yes. Because the helmet is worn 23 hours a day, the baby sleeps in it. The helmet is light and does not change the safe back-sleeping position.
