How to stop dead ends and split ends when straightening hair?

your best bet it to use a few products to help the breakage and u should probably set ur flat iron on a lower setting if u have fine hair it should be set on the lower end of the settings medium hair its about the half way mark and mive curly almost all the way up. Depend on ur hair type will depend on the products u can use. Paul Mitchel Relaxing Balm mixed with some gloss drops is a good combo. Matrix also makes a thermal spray that works amazing! Also if u do weekly conditioning treatments that really helps i cant recommend u getting these products from ur local drug store or grocery store but i can recommend getting these products from a salon *super cuts usually has cheaper prices* hope this helps
