Rounded Memory Flex bristles glide gently through the hair, loosen knots without pulling and protect the hair structure, for well-groomed and straight hair. Flexible brush body, for even pressure distribution and stimulating effect on the scalp. Ventilation holes in the brush body allow more air to blow-dry the hair, for faster drying times, to prevent hair and scalp drying out. Ergonomic brush handle and seamless design for maximum comfort during brushing: the iDetangle brush is made in one piece to prevent hair from getting caught between the brush head and handle.
