Benefits of manual capping system

Penguin Cold Caps is a manual capping system. This means this caps need to be cooled in a bio-medical freezer or with dry ice in one of our specially designed Penguin cool boxes before use. They are changed every 20-25 minutes during chemo. But it also means patients are free to walk about, visit the bathroom and continue wearing the caps when they leave the clinic.

This is important because, depending on what drug regimen you are on, it can take several hours for the toxicity of the chemo to reduce to a level  that will no longer damage your hair follicles. Removing the cap too soon can undo all your good work and allow the drugs to penetrate the hair follicles as they warm up.

Manual capping also gives you a much closer cap fit than machine-based systems. This means every part of your scalp is in contact with the cooling gel to ensure the chemo drugs are kept at bay. Patients using the machines often report bald patches appearing where parts of the scalp  have not been sufficiently cooled.

Cap design

While there are other manual cold caps providers, that use “off the shelf caps” that are not specifically designed to save hair from the effects of chemotherapy.

Penguin Cold Caps have been carefully constructed using materials with exceptional thermal insulation properties, so they stay at the correct temperature for longer. This means patients don’t have the hassle of having to change the caps as often, making the system far simpler and easier to manage. Just imagine having to juggle 3 or more caps in a cooler and then remember which one you used first.
– These are the reason why we only supply 3 caps in each kit.

The hairline is an area of the scalp that be difficult to cool and as a result it can be prone to additional hair loss. To counter the problem, Penguin is the only cold cap company to provide a Crylon gel filled headband that enables patients to secure the back and sides of the cap tightly to the head, ensuring protection for the entire scalp.

Other providers are unable to achieve the results we do.

A friend with precisely the exact diagnosis and treatment lost 30% of her hair using machine capping. Penguin Cold Caps are colder and fit closer to your head, which is why they work. If you want to keep your hair, use Penguin.

Success with AC, and other strong drug regimens

Many patients are told by their oncology team that Cold Caps won’t work on AC – but that’s not true. Many patients using Penguin Cold Caps have achieved great success on AC. As long as you follow your reps advice, there is no reason why any one needs to know you are going thru chemotherapy.

Bronwen claimed to saved 90% of her hair with Penguin Cold Caps on a combination of AC and Taxol.

She said. “I would 100% recommend cold capping to anyone else. Saving my hair has had a huge positive impact on my cancer journey. It has helped me to keep my identity. I’ve continued to work throughout my treatment, and it’s given me the strength to continue every day. For these reasons,  if you can save your hair…then why not!”

Although the cold can be uncomfortable, the process does get easier with each session, and I soon got used to the coldness. Ultimately, it is bearable and well worth the effort. I was able to cover any thinning spots with a retro-style turban headband. Nobody notices unless I tell them.
