We receive, at least one, if not more, tickets a week in the CCHD on this very question: "Can I cut a bang into XYZ wig?". So here are our thoughts!
Short answer: Yes, you can cut synthetic, synthetic blend or even human hair fiber, but the result will NOT be the same as cutting your bio hair. I learned this the hard way after destroying several wigs early on in my wig-wearing years.
So, we have a few suggestions when considering such a plight:
1) We HIGHLY recommend having a professional, with experience cutting synthetic fibers, cut in the bang or at least provide some additional consultation, especially if this is a piece you have significant money invested. Synthetic Fiber is very different than human hair and is the equivalent to a fiber/fabric (think cotton) vs the actual texture of bio hair. Thus, cutting synthetic hair the same way as bio hair, will NOT result in the same outcome.
Also, many times synthetic hair may need to be thinned in the front, especially if the style is a long bang or one length style and a professional WITH experience in this area is really a great resource.
If you do not have that resource available, another suggestion is to pull out one of your older wigs to practice on, and invest in a pair cutting shears made for synthetic fibers and give it a try it yourself!
2) The style of the wig is another point of consideration. The best styles for cutting in a bang, would be those that are either a NO part (standard cap) or a mono top. A side mono part style, like the Evanna by Rene of Paris, may not respond as well to a bang, given that the part is hard-set into the design. The side parts are made for that part, and if you try to adjust the parting, you will see the wefting and stitching. Thus, cutting a bang into this style, may not achieve the desired result. With the Evanna, you could potentially cut a side long bang, with wispy layers, but again, it may NOT lay flat or give you a straight-across bang affect. This is also a wavy textured wave, and though you could use steam to flatten the fiber, the bang may not lay flat.
Side part styles like Evanna by Rene of Paris, are not recommended for cutting-in a bang:
Whereas, a style like the Aria by Rene of Paris, with a Lace-front and standard cap (permatease) may produce a better result, especially with the lace-front. The fiber may be more likely to lay flat and produce the desired result. Sometimes too, cutting in a bang in a standard cap, helps to further disguise the permatease top.
3) Last word of caution, go slowly. When I cut my wigs, I cut at an angle, into the fiber and do so a little at a time, to see if the fiber is responding well and if not, I can usually stop before it is too late.
Happy hair cutting and if you have additional tips or tricks you would like to share, or would like to share a photo of your successes, please contact us at the CCHD (Client Care Help Desk) as we would love to hear from you!
