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.)
