High-quality, monofilament wigs (with wefted back and side) construction gives the appearance that the hair is actually growing from the scalp.
This monofilament material allows the wig to be parted in any direction. Thin, breathable fabric is placed at the hairline or the front of the head toward the crown section. Plus, they can be styled with hair accessories
Many of these wigs will have this monofilament material on the top portion of the wig, and wefts through the back & sides.
(Wefts are the ribbon-like bands that the hairs are attached to).
See diagram below:
The top portion of the cap is specially woven to allow for comfort and excellent ventilation. This helps to prevent irritation and itchiness. It will "Breathe" while being worn, thereby preventing heat and moisture build up.
Monofilament is considered to be one of the most desirable of wig types. Most women, especially those who wear wigs every day, feel its superior "wear-a-bility" and natural look more than justify the additional cost.
Most women going though chemo-therapy will opt for these monofilament wig caps (medical wigs)- due to the added comfort & security.
