Hi, would just like to say firstly that I have found your site really helpful and informative, thanks! I’m an 18 year old female, currently straighten my fringe every day and I’m really concerned that this will cause permanent damage. I know that straightening can make hair brittle, causing it to fall out until a new one grows, but I read somewhere that heat from straightening irons can travel up the hair shaft and burn the follicle, meaning the hair will never grow back. Is it possible to damage the follicles like this? I have had a look through the site but can’t find a definite answer. Thanks.
Straightening your hair everyday will make the hair brittle, as you already know. However, it will not kill your hair follicles, which are below the skin and not impacted by hot irons and the like. On the other hand, chemical straighteners could kill the hair roots if used improperly.
