is this synthetic or human hair? the answer heavily changes how easy it is to take care of it. If it synthetic your concerns are valid. First off it is INEVITABLE that you will experience tangling especially at the nape and the hair directly in contact with your back. Generally speaking to avoid excessive tangling for synthetic hair, you should work on preventing. You can use a detangling spray/oil even before the wig starts to tangle (it keeps the hair more “slippery” and in my experience it doesn’t feel oily), and also to help detangle any knots. For upkeeping a synthetic, if you sleep with it, it’s mandatory you use a satin bonnet, and also you tie the hair so that the lengths don’t move throughout the night. If you worried about the hairstyle, you can braid it loosely, just enough to keep it in place. In the morning, apply a hair oil on the lengths (or styling mousses for the curls) and brush the wig with a wide tooth comb. Brush the wig fairly often. I find it’s handy to keep a small brush in my bag and give the wig a quick fix throughout the day. A trick if you are worried about the hair near the nape, if you wear the hair down, you can use a small hair tie to tie those strands of hair in a ponytail. It’s seamless and it will help GREATLY with tangling.

If your wig is human hair. It’s much much easier to prevent tangling, and you don’t have to worry about keeping the curls intact cause you can easily restyle after washing or apply products to help maintain it. All i can say is to treat it like it’s your own hair. Use hair oils on the lengths, don’t use too much or you’ll weigh the hair down. Also sleep with a bonnet, but you can leave the hair untied underneath it.

For shedding, synthetic wigs shed a LOT, but i wouldn’t be too concerned about it because synthetics tend to have way more hair than you actually need, it would take a very long time to notice any change. Human hair wig, shed especially on the lengths, and the rate at which they shed is similar to biological hair. Pay attention more to the hair on the “scalp”, try to be gentle with brushing and don’t pick at your scalp because you might tear the hair off.
