Long loose curls!!?
I am not certain about what you mean specifically, but here is how to make loose curls. I use a curling shapoo and conditioner. I blow dry my hair completely and then with a Ceramic Curling Iron like Chi, I start taking small sections of my hair and curl them. I do not curl all the way to the roots. I only curl the bottom parts. The smaller the sections, the better the curls look.
Because you have long hair, you should part more sections and it depends on how curly you want the loose curls. My hair is to the middle of my back, but it’s fine so it won’t hold a curl long unless i spray it with a lot of hairspray. I part my hair down the middle, then i part the portions horizontally (by the ears) and then part those vertically- so you will have 4 on each side of the head. Then I spray it with some curl spray and then roll each section in rollers or with the curling iron. Hope this works for ya.
If you want long loose curls then i suggest you rough dry your hair but holding the air flow down so you don’t cause frizz and using the right frizz maintaining products. If you have straighteners that get quite hot on the outside aswell as on the inside, you can use these to produse a natural soft curl/loose curl. (Just wrap your hair round your straighteners and hold for 5-10 seconds depending on the thickness of your hair). The looser the curl you want the bigger the section you should take. You can either part your hair in two, so even amounts of hair on either sides. Or take horizontal sections using a grip/clip to hold the rest of the hair out the way. Then curl each section, remember using big sections in order to achieve a loose curl. Try it out and see how you best get on. Remember to use products aswell to keep in your curls.
