Hi Kristiina,
Thank you for your question! 🥰
The device in question works really well for shoulder-length hair, when the length is at least below the chin. The 25 mm cylinder creates beautiful, natural curls and relaxed waves that work really nicely in a bob – the result is airy and movable, not too tight.
The hair shouldn’t get tangled or stick to the device when the hair is dry and well detangled before styling, and the sections are of moderate size. The device pulls the hair in a controlled manner and stops if the section is too thick or placed incorrectly, so the use is safe and easy 😊
In fine but voluminous hair, curls can definitely succeed, and longevity can be achieved with small tricks. We recommend using 185–200 °C heat, considering the condition of the hair, choosing a slightly longer timer for a tighter curl and letting the curl cool before combing. A light hairspray for finishing helps as well. The curl may initially be tighter, but it will fall beautifully into a relaxed wave throughout the day 💕
Hope this was helpful!
