Wella Invigo Sun After Sun Conditioner, is a restorative and nurturing conditioner. It restores and strengthens weakened, dry and split hair. In the summer, when the sun is shining from morning to evening, your hair especially needs protection from UV rays, chlorine and saline, which can damage the hair's surface and make it dry, matte and difficult to handle. We recommend that you not only protect your skin with sun factor, but also remember to look after your hair in the summer.
