Your hair type can range from the fine blond hair of Scandinavians to the thick, and sometimes coarse hair of Asians and Indians. Straight hair can be texturized with perms, hair setting, and hair care products. Thin, straight hair often benefits from being colored, which adds texture and fullness to each strand. Very coarse or thick straight hair may be difficult to perm, requiring extra time and additional perming rods in order to achieve the proper final look. Simple, geometric haircuts (like bobs) are a natural for straight hair of any texture. Very straight, thick hair is often resistant to perms-stubborn about taking a curl and likely to need frequent perming to maintain the hair's new texture.
