Description

  The present invention relates to a hair iron for returning hair to normal acidity, and more particularly, to a hair iron having an ion balance function for drying hair and setting the hair curled or straight.

  When brushing the hair with a brush or a comb, static electricity is generated in the hair, and this static electricity affects the cuticle of the hair and causes damage to the hair.

  In order to solve this problem, conventionally, it has been proposed to apply negative ions to the hair and allow the negative ions to penetrate into the hair, thereby further increasing the hair.

  However, since there are positive and negative static electricity, it may not be appropriate to apply only negative ions to hair.

  Then, the hair iron of the following patent document 1 was developed. For the purpose of providing a curling iron that is easy to use and can improve the health of the hair, the curling iron has a pair of arm portions that are pivotally connected to each other, and the two arm portions. In the hair iron having a heat generating portion, the arm has an ion generating means for generating negative ions, an ozone generating means for generating ozone, an ion generating means and a power supply circuit for supplying electric power to the ozone generating means, and the arm One of the members has a structure in which a convex portion having a hollow inside is formed at approximately the center.

  However, the hair iron shown in Patent Document 1 generates only negative ions. Therefore, it is necessary for the user to determine whether the hair is positively or negatively charged, and to apply negative ions. Even though the hair is negatively charged, In the case of being charged, the negative ions may be excessively applied, and the acidity of the hair may become more acidic than the normal range, which may adversely affect the hair.

[Operation of the present invention]
The effect | action of giving a positive ion or a negative ion to hair is demonstrated based on explanatory drawing of FIG.

  The normal pH value of hair is weakly acidic at 4.5 to 5.5, but when the hair is dried, etc., the state where the number of positive electrons at pH 4.5 or lower on the left half side in FIG. 1 increases In the case after shampooing, etc., the negative electrons having a pH of 5.5 or more on the right half side in FIG.

  In other words, dry hair is easily charged with positive electrons and is likely to generate static electricity, and if only negative ions are continuously applied, it is charged with negative electrons and the negative ions are less likely to adhere to the hair. By applying ions and negative ions alternately, the negative ion effect is enhanced for positively charged hair by neutralizing positively biased charges.

  Hair after hair coloring, perm or shampoo is inclined to alkalinity, which causes the cuticle to open and make it easy for nutrients to go out.By applying positive ions, the cuticle is tightened to weaken the alkaline hair. The hair is led to acidity, and on the contrary, the dried hair tends to be acidic, so that static electricity tends to be generated.

  If the wet hair is rubbed by rubbing, etc., the open cuticle will be damaged, and it may cause split ends and broken hair. By applying positive ions, the cuticle opened with moisture is tightened after shampooing. By drying firmly on top, it can prevent dryness that causes hair to hurt and keep moist and glossy hair.

  By alternately generating positive ions and negative ions, the hair inclined to alkalinity is led to weak acidity while drying firmly after shampooing, and the negative ion effect is enhanced by alternately generating positive ions and negative ions.

  When negative ions are applied to positively charged hair, neutralization is promoted by attracting each other. If negative ions are continuously applied as they are, they will be negatively charged and become alkaline, but the present invention neutralizes negatively charged hair by alternating generation of positive ions and negative ions, and by repeating this, The pH will be in or close to the normal range of 4.5 to 5.5, and will be optimal for the hair.

  The hair iron according to the present invention can generate positive ions and negative ions simultaneously or alternately, thereby making it possible to bring the hair acidity to a normal state.
