Here’s what you need to know…

If you want the sleekest, most manageable and frizz-controlled hair of your life, there’s only one word you need to know: Keratin.

Keratin is “the main protein of the hair, skin and nails”, says Jez Barnett, founder of KeraStraight.

“Keratin makes up to 91 percent of hair and contains 16 different amino acids, with cysteine being the most important one as it creates the sulphur bridges in hair that give it it’s internal strength.”

If your natural keratin levels are low, your hair can appear dry, frizzy, dehydrated and damaged, which is where the man-made treatment comes in…

In fact, it even has the royal seal of approval and is loved by none other than Meghan Markle.
