How long can you keep a sew in in your head?
How long does a sew-in last? If you’re showing your sew-in love and taking proper care of it—more on that in a bit—it’ll last up to six to eight weeks, says Nash. If you try to keep it in longer than that, you’re risking damage to your hair and scalp (aka irritation, excess oil buildup, and breakage).
Why do sew in itch so bad?
At times, stylists may braid your hair too tightly and or sew the hair in too tightly. When the hair is pulled too tightly, hair follicles become inflamed. This may lead to itching.
