The Squargonomics hair brush is perfect for adding extra volume to your hair. It is a thermal ceramic brush with a square shape, featuring a ceramic coating that ensures quicker heat transfer, facilitating rapid drying of your hair while maximizing heat from the styling. Due to its square shape, it easily grips and curls the hair. The curved edges are gentler on the scalp to provide additional comfort. With a silicone handle, it offers comfort, balance, and improves control of the brush for enhanced performance. It helps to smooth the hair and create volume from the roots while minimizing damage to the hair. Available in 5 sizes: 20mm, 25mm, 33mm, 43mm, and 53mm. The larger the cylinder size, the more volume is added to the hair, making the 20mm brush excellent for short hair, while the 53mm brush is perfect for long hair. Diameter of the ceramic tube: 53mm. Brush length: 25.8cm.
