The Siztaz aThermo Cap makes hair masks, deep conditioners, and oil treatments more intensive by retaining your natural body heat.
No electricity, no microwave – just put it on and let the heat do its work.
Thanks to its lightweight 2-layer construction (printed fabric & waterproof interior), your treatment stays pleasantly warm and can penetrate deeper into the hair fiber. Your curls will become softer, more defined, and healthier in the long run.
Practical & suitable for everyday use
The Thermo Cap fits comfortably, doesn't leak, and can be worn while tidying up, reading, or relaxing.
It replaces foils, disposable shower caps, and heavy, electrically heated alternatives – a clean, sustainable, and simple solution.
