It is a very easy and simple question actually, we all know Closure Wig come with a certain portion of lace laying in front of Remy human hair wigs, which can be divided into different kinds of lace closure wigs in accordance with the lace size. 4x4 closure wigs are those with 4x4 lace size. The Pros Easy to Apply and Remove: 4x4 Closure Wig generally rely on its more convenience and easier installation. Compared to traditional 13x4 lace frontal wigs, you don't bother to cut longer lace edges, just put it on and manage it in much easier ways. It can easily apply and take it off yourself. This saves you time and money. Natural Looking Hairline: The sheer material blends against your skin to create the appearance of a natural hairline. Lace Closure Wigs are among the highest quality. Styling Versatility: 4x4 lace closure wigs are a popular choice for weddings, as many brides prefer to wear their hair up on their special day. You can have a high ponytail one day, bangs the next. You can style your hair to suit your mood! Affordable: The price is relatively more affordable than that of general lace frontal wigs. Part Anywhere: A lace wig allows for high ponytails and parting anywhere you like, even down the center. The Cons Be Limited: 4x4 closure wigs? I think most part of them will come to its narrower parting space. Pretty clear to the eye, the lace size is 4x4, which means 4 inches vertical and across the hairline, so if you part horizontally, 13x4 will offer more versatile hairstyles to choose while 4x4 is limited. Reapplication: This is required every 3 to 4 weeks Clean-up: Cleaning must be done before reapplication, which can be time-consuming. I hope you have found this guide useful.
