If bad hair days keep cropping up one after the other, have you ever considered a keratin treatment? Whether or not you've heard of this super sleek miracle worker, its always best to do your hair care homework before you look to try it. To help you decide whether or not to play for keratin keeps, we sat down with Nina Ellis, Brazilian Keratin Treatment expert and Marketing Director for the Kashmir Keratin Hair System, to pick her brain and learn all there is to know about this innovation. Read below to get the full scoop on the unique benefits.

So Nina, what exactly is a keratin hair treatment?
Also known as Brazilian hair treatments, keratin hair treatments are a semi-permanent, hair-smoothing, curl-softening professional chemical process designed to make hair straighter, shinier and even healthier. The treatments are usually made up of a chemical like formaldehyde (which creates the long-lasting smoothing effect), conditioners, and some keratin (a protein our hair is made of to add strength).

What types of hair are ideal candidates for keratin?
Keratin is more of a restorative treatment. Even if you have a healthy hair type, it still strengthens the hair shaft and makes your hair more resilient. If you usually style your hair straight, a keratin hair-straightening treatment could shorten your blow-dry time by 40% to 60%. You can forget about frizzy hair as well. The treatment is so effective, you could walk out in moist or light rain and your hair won't change.
