The Double S Pro brush is a unique and innovative straight styling tool by Marilyn. Perfect for natural hair types - whether medium, coarse, fine or frizzy - this brush can also be used on chemically treated or porous hair, as well as hair extensions. The Double S Pro showcases Marilyn's pattented hourglass shape that adapts to the contour of the head for the most tailored and efficient creative styling. 100% natural reinforced boar bristles sit perpendicular to the barrel for ideal straightening without extreme volume. This Double S Pro is made with a lightweight 3inch round barrel, a size best used on medium to long hair. No winding necessary when styling - simply lift the hair in one easy motion with maximum tension. This brush allows for more control and better finishing of hair roots and ends, simultaneously stimulating the scalp and redistributing hair's good and natural oils. Shine and polish hair as you brush for long-lasting style. What makes the Double S Pro even more special is the ceremic coated barrel which helps retain heat when blowdrying, so the brush acts like a styling iron and hair dries even faster! Designed with a comfortable foam grip, the Double S Pro is a matchless styling product that straightens while adding shine luster to your look.
