Sleek Angel High Gloss Serum

"Having thick curly hair I use a serum every day to keep the frizzies away and to add some shine. This serum from Angel Fish had a gorgeous coconuty smell and wasn't too heavy, as some serums can be. It made easy work of my thick curls and left me with silky smooth, defined waves all day. A brilliant product, and easy on the pocket too."
