The following are some information about Types of Wig Cap :

Monofilament + 100% Handmade
These are the best quality wigs using monofilament and hand tying. This luxury product provides 100% comfort. The mono top is woven onto a fine base and is undetectable to the eye. It looks like skin and is very realistic. The remainder of the wig is a fine mesh and the hair is hand tied to it making it very lightweight.
Monofilament + Weft
The hair is woven onto a very fine mesh on the scalp area (mono top) which is invisible against the skin. These are probably the most popular wigs. The wefted area is machine made with hair sewn to strips of material (ribbons). The wefts have gaps in them to allow the head to breath.
100% Handmade
The whole wig cap is made of fine mesh. Whilst this type of wig does not have a mono top, as the whole wig is hand tied so still gives the appearance of skin.
Wefted Wig with Mono Parting
Wefting means the thin strips of material (ribbons) that the hair is machine sewn to. This particular cap has a mono parting. Again, this gives the appearance of skin, but usually these wigs are a little cheaper that the full mono top. The parting is not adjustable.
Small Mono Part
Wefted wig with small mono area, usually at the crown.
Wefted
Wefted means strips of ribbon like material which the hair is machine sewn on to. This is the usual construction of a wig and makes it more lightweight and cooler to wear. Wefted only wigs are a cheaper variety of wig cap. People with hairloss who need to wear a wig every day usually prefer a mono top wig as they are more realistic. Wefted wigs tend to be frizzed very slightly at the root .
Lace front Wig
Lace front wigs are 100% hand tied as mentioned previously, but with a lace (netted) front to give a realistic *join* at the forehead. These wigs do not need any adjustment to the front of the wig. Lots of 100% hand tied wigs are made this way giving an invisible line around the forehead.
However, some lace front wigs have lace that is left longer at the front of the wig so that it can be trimmed to the customers desired length. This is usually then glued to the hairline to give a realistic look. Either way has the same effect. Videos of how to attach these wigs to the head can be found on You Tube, in fact, there are lots of helpful hints on wigs generally on You Tube.
Top Fillers
Top fillers are not full wig but a smaller piece that can be clipped on to the hair on the scalp area. These are meant for people who still have some of their own hair. Some of these pieces have mono tops and others have a honeycomb base which allows for the wearers own hair to be pulled through the holes. These bases come in different sizes and can be small (closures) or are big enough to cover the whole scalp area, for more information pls refer http://www.wigsbeautyexp.com
