The Hairdreams brush has multiple layers of different types of bristles to stimulate and release all the natural oils from your scalp and help distribute them all the way to the ends resulting in shinier, luminous hair. The tri-bristles are designed to be flexible yet strong, making it ideal for all kinds of extensions because you can safely and thoroughly brush over bonds and attachment points. This brush was specifically designed for longer hair and is ideal for preventing shedding and matting with extensions.
