Okay, so it's the middle of winter in most of the country, and you're wondering why we're talking about rinsing your hair with cold water. Shouldn't that be saved for the dead of summer, when the coldest water you can get out of the tap is still lukewarm compared to January's frigid temps? In a word, no. Rinsing your curls with cold water is something that should be done year-round, and it plays a vital role in the way your curls turn out when they're dry! Wanna know why?
Rinsing with cold water closes the cuticle, the outer layer of the hair that's similar to shingles on a roof. When you wash with warm water, the warmth opens the cuticle, allowing the products to penetrate each strand of hair on your head. The molecules of conditioner go under the shingles, filling in the gaps in the hair strands and strengthening the hair. But if you rinse with warm water as well, a lot of the molecules essentially go right back out and down the drain! You don't want to undo all the conditioning you've done.
What you want to do is trap some of the conditioner molecules in the hair so it can stay moisturized and frizz-free. (Isn't that what every curly wants? Heck yes!) So if you rinse with cold water, you close those shingles back down and retain some of that moisture you just added. On top of that, when the shingles are closed, the hair appears shinier and smoother, which helps reduce a frizzy look also.
If you think you won't be able to handle a cold rinse, especially in winter, it's okay; just take it gradually. Point your showerhead down and flip your head over before adjusting the temp, rinsing only your hair; or keep a large cup in the shower and dump cool cupfuls over the lengths of your hair, avoiding the scalp if you want. Try making the water a little cooler each time until you get it as cold as you can. The colder the water, the better the results! You might be surprised at what you can handle before too long.
After your cold rinse, be sure to style with Controlled Chaos Curl Créme to finish your frizz-free look. (You can keep your head flipped over to apply the Curl Créme and scrunch the excess water out before you even step out of the shower!) Think of a cold rinse as a necessary part of your curl care routine; before you know it, you will wonder how you ever lived without it!
