Do keratin hair straighteners really work? How can you tell how long they'll last? And, which ones are safe? 
 
Hi 

Jennifer asked us how keratin hair straighteners work and she wants to know if they're safe. To answer her questions, Perry and I discuss the biology of hair and the chemistry of keratin products. 
  • What makes hair curly? (Including our "hair is like a ladder" analogy.)
  • The 3 types of hair straighteners (and which one is best!)
  • 3 reasons why humidity makes hair frizzy (and what you can do about it.)
