The Roots Style Glam All Purpose brush is a colorful mix of style and utility. Its flexible bristles are gentle on your hair and the rounded tips prevent scraping of the scalp and the hair cuticles. In fact, they massage the scalp stimulating the natural oils. Its trendy yet sturdy design makes it durable whereas its colors brightens even the most gloomy hair days! All our paddle/oval brushes have a hole in the cushion which acts as an air vent. This helps us to get a gentle brushing experience. There is no defect in the brush, and is a part of the design.
