Hair iron

A hair iron or hair tong is a tool used to change the structure of the hair with the help of heat. There are two general kinds: Straightening irons, used to straighten the hair, and curling irons, used to make the hair curly.

Straightening irons may also be called flat irons, but not to be confused with clothes flat irons. There are also irons, called styling irons that can be used to both straighten and curl the hair. One tool means that you can straighten one portion of the strand and curl the other.

Children’s or superfine hair

Children’s hair is often a problem because it is supremely fine and may be difficult to care for because of its nearly downy softness and fluffiness. Up until the age of 7-10, this fine hair will remain about the head.[citation needed]

Children’s hair is different from adult hair in texture, density, and likely also color, body and so on. Hair's traits change over time as humans physically develop, and even age. Like the rest of the human body, (example, teeth), hair has different stages of development spanning the full lifetime from birth to death.

Very curly hair requires unique care. Hair can be ruined if brushed out dry. There are many different kinds of hair products catering to frizz control and curl definition. Curly hair tends to dry out easily, leave-in conditioner can help.[citation needed] Hair that is very curly often does not require detangling.

Hair coloring

Hair coloring is the process of adding pigment to or removing pigment from the hair shaft. Hair coloring processes may be referred to as dyeing or bleaching, depending on whether you are adding or removing pigment.

Temporary hair tints simply coat the shaft with pigments which later wash off.

Most permanent color changes require that the cuticle of the hair be opened so the color change can take place within the cuticle. This process, which uses chemicals to alter the structure of the hair, can damage the cuticle or internal structure of the hair, leaving it dry, weak, or prone to breakage. After the hair processing, the cuticle may not fully close, which results in coarse hair or an accelerated loss of pigment. Generally, the lighter the chosen color from one's initial hair color, the more damaged it may be. Other options for applying color to hair besides chemical dyes include the use of such herbs as henna and indigo, or choosing ammonia-free solutions.
