Description

TECHNICAL FIELD The present disclosure relates to compositions and methods for styling hair, particularly, to compositions and methods for temporarily straightening curly or wavy hair. BACKGROUND Consumers with curly or wavy hair often desire to temporarily straighten their hair for a change in appearance, and then switch back to their curly style without damage. In addition, reducing the curls of very curly hair may increase the manageability and ease of styling of such hair. Currently, temporary straightening curly/wavy hair or frizzy hair typically involves the use of hot tools such as blow dryers and/or flat irons. The high temperature of the blow dryers and/or irons leads to a breakage of hydrogen bonds in the keratin of the hair, achieving a temporary straightening. The hydrogen bonds are formed again by the action of moisture, so that the hair reverts back to its original shape over the time because of air humidity or after washing or damping the hair. Longer-term and/or permanent straightening is usually achieved by using chemical straightening treatments, such as relaxers, with high pH. The shape of the hair is largely determined by the disulfide bonds linking two cysteine moieties of the hair keratin. To achieve a longer-term and/or permanent shaping or styling effect, it usually involves cleavage of the disulfide bonds by the action of a sulfide- or thiol-group containing reducing agent or relaxing agent. After the hair has been brought into the desired shape, new disulfide bonds are formed by applying an oxidizing agent such as hydrogen peroxide, thus fixing the shape of the hair. The use of such agents, however, may cause damage to the hair and weaken the hair, resulting in subsequent breakage. Conventional products that provide hold, such as styling gels, although may also provide straightening effects to the hair, usually flake on the hair and result in very stiff and unnatural look hair. In addition, conventional hair straightening routines are usually time-consuming. As such, there is a need for new and improved compositions that can be simply applied to hair and provide straightening effects to curly or wavy hair that would not damage the hair, while imparting various additional sensorial properties to the hair such as frizz control, softness, smoothness, and/or shine. The present disclosure addresses these needs and concerns and relates to new compositions and methods that can provide styling effect, particularly, a temporary straightening effect on curly/waving hair without the requirement of using heat. It has now surprisingly been found that a combination of components described herein allows for a balance between straightening performance and consumer desired look and feel, even under high humidity condition, and is useful for providing desired temporarily straightening effect to curly or wavy hair through a simple application routine without the use of hot tools or harsh chemicals such as reducing agents or relaxers, while at the same time delivering additional advantageous sensorial benefits such as frizz control, natural look and feel, to the hair. The temporary straightening effect and other benefits such as frizz control imparted to the hair are lasting, such as may last under high humidity conditions and until the next hair wash, without any damage to the natural curls. SUMMARY The present disclosure relates to compositions that provide temporary straightening effect to curly or wavy hair, while at the same time providing one or more additional benefits such as frizz control, softness, smoothness, and/or shine to the hair. The compositions may be used as leave-in compositions for styling hair, such as for temporarily straightening the hair, and may at the same time providing frizz control and/or other sensorial benefits to the hair, without the use of heat or chemical relaxers. The disclosure also relates to methods of using the compositions for styling hair, in particular, temporarily straightening curly/wavy hair, while in some embodiments further providing additional sensorial benefits such as frizz control to the hair. In various embodiments, the hair styling compositions according to the present disclosure comprise (a) at least one polyphenol; (b) at least one polysaccharide gum; (c) at least one polymeric emulsifier; (d) glyceryl polyacrylate; and (e) water. Optionally, the compositions may further comprise at least one latex type film former chosen from acrylate-based polymers, polyurethane-based polymers, derivatives thereof, or combinations thereof at least one vegetable oil; at least one humectant; and/or at least one ester other than glyceryl polyacrylate. In various embodiments, the hair styling compositions disclosed herein are free or substantially free of chemical relaxing agents or reducing agents. In certain embodiments, the compositions may be free or substantially free of fatty alcohols. In some further embodiments, the composition disclosed herein may be free
