Since your hair may be especially fragile, it's important to choose your styling appliances carefully. Look for electric rollers that are covered in a velvety material. The usual prong-type rollers may cause hair breakage. Covered curlers will protect the hair. The result? A smooth, long-lasting curl. Using heat is the quickest way to curl, but it's not always the gentlest, so be sure to condition your hair to avoid any added dryness that heat styling may cause.
