Description

  The present invention relates to a hair styling apparatus and method for straightening hair strands at the scalp site, and more particularly, a non-volatile styling active can be used in combination with heat and tension to create a smooth and straight appearance on the hair. The present invention relates to a hair styling apparatus and method.

  It is well known to use steam to set or style hair, and a structure that releases steam is used to improve the results obtained when curling, straightening and setting hair with heat assistance. Many attempts have been made to provide devices such as hair rollers, curling irons, and flat irons.

  Previous attempts have included the use of some sort of volatile active substance in the hair stirrer. However, the use of volatile active substances results in a very limited hairstyle that lasts less than a day.

  Surprisingly, it has now been found that delivering non-volatile actives from hair styling devices can coat hair better and more uniformly. This approach can deliver a thin layer of active substance to the hair, resulting in a hairstyle that lasts all day. This approach also eliminates the problems associated with the use of styling product forms such as mousses, gels, and sprays that produce large agglomerates (local deposition) of the active material and less uniform coatings. Surprisingly, it has also been found that the use of moisture delivered in combination with styling actives and heat improves the effect of reshaping and re-styling hair. In addition, the use of water may facilitate hair shaping and may assist in the uniform distribution of the styling active.

  The present invention relates to a hair styling device for smoothing and straightening hair strands at the scalp site, the device comprising two arms which are attached by hinges and are movably opposed to each other, each having a hair strand gripping means. Delivering two arms comprising, a heating means incorporated in the gripping means and providing heat to the hair strand, and a non-volatile styling active delivered as a droplet having a Dv (90) of less than about 30 μm; A combination of the delivery means of the gripping means and a reservoir in fluid communication is provided.

  The present invention further relates to the use of water that facilitates hair shaping and aids in uniform dispersion of the styling active. The present invention further relates to a method for straightening hair strands at the scalp site, wherein the straightened hair passes under tension between the gripping means, the gripping means being a heating means and a styling comprising a non-volatile compound. And the styling active is delivered as droplets having a Dv (90) of less than about 30 μm.
