Jason explained: "Kate's hair always looks so glossy and healthy, especially in this vintage curl style. The key to keeping curls in place is to add moisture to the hair."

During the winter months, there is less humidity and less moisture in the air. Because of this, your scalp and hair become drier too, and it's the moisture and your hair's natural oils that keep hold of the curl. But there are a few things one can do to keep curls in.
Check out the shine!
"The first step to long lasting curls is strong hair which can be achieved by using hair serums or oils with bond building technology. I love 'Bstyled Hair Serum' which also has marula oil that nourishes hair from root to tip, exactly what you need for heat-styled curls."

He added: "Before any heat styling you must use heat protectant, not only to keep them in place but to also keep hair healthy. Using one that is made especially for curls can also help as it can also help control frizz, which is why I love 'Bstyled Heat Protection Curl Definer.'

"Another way you can keep curls in place is by using a thickening mousse on your hair before using the heat tools. Mousses have been designed to hold the weight of your hair when it's in a curl, so it's a no-brainer that they would be great for holding your hair into any style."

"And lastly another way to get your curls to keep is to style your hair on second day hair. Second day hair (aka the day after you wash your hair) is the best for styling because your natural oils have readjusted and have a better grip on the hair and the products you put into it, making your desired hair style hold better."
