I have learned alot about hair striaghteners.....

I use a hair straightener practically every single day, but I never actually knew and comprehended how it worked...until now. Doing a little research I have found out that the hair iron works by breaking down the hair's hydrogen bonds found in the hair's cortex, which causes hair to bend and become curly. The heating ceramic plates in the iron are more effective due to their constant heat, with a very fast heat-up time (less than 10 seconds). Not every kind of straighteners have ceramic heating plates. The ones with out ceramic plates have cheaper coatings that wear off very quickly and cause much more damage to the hair. There are two types of damage that all flat irons cause: heat damage and mechanical damage. Heat damage is unavoidable when using a flat iron. The hotter the flat iron gets, the better it works but the more heat damage is caused. Less mechanical damage is caused to the hair when smoother plates are used. Most plates are aluminum and coated with something, such as a hard ceramic coating. As cheaper coatings wear off, the levels of mechanical damage increases.
