We recommend keeping hair styled, especially as it grows longer. When hair is left down, it is more likely to tangle and come into contact with friction, which can lead to split ends and breakage. Therefore, having your hair in a loose style is the best way to protect your strands. Hairstyles shouldn't be too tight, though, since this can cause pain, discomfort, and even pull on the follicles, causing traction alopecia. If you feel any tightness at the scalp, loosen your hairstyle!
