Which client demographic commonly prefers nonelectrical thermal irons?

Clients who have excessively curly hair often prefer nonelectrical thermal irons because these tools allow for more controlled styling and the ability to achieve specific textures without the risk of heat damage that can be caused by electric tools. Nonelectrical thermal irons can be heated to a desirable temperature on a stove or other heat source, giving the stylist the ability to adjust the heat based on the hair's texture and needs.

Excessively curly hair often requires a gentler approach to heat application in order to avoid frizz and maintain the integrity of the curls. Clients with this hair type may also seek the definition and smoothness that a nonelectrical iron can provide, stemming from the traditional methods of curling or straightening hair.

In contrast, clients with straight hair typically do not require the added heat styling provided by thermal irons since their hair is naturally smooth, while those with wavy hair may use electric tools for convenience. Lastly, clients with fine hair may prefer lighter, less intense heating to avoid damage, which might lead them to choose lighter styling tools rather than nonelectrical thermal irons.
