When it comes to lace products, which is better: bleached knots or injected strands?
When the strands are individually knotted onto lace, the knots are visible and need to be bleached. The bleaching helps to conceal the dark knots however the hair is literally bleached. This bleaching process generally leads to the knots becoming dry and brittle over time, resulting in breakage and shedding of the hair.
The knots are generally bleached just at the hairline however some clients prefer the bleaching of ALL knots. Again, the end result is shedding piece that will become too thin to wear.
When the strands are injected, they are not knotted, thus no need to have the knots bleached. The end result is a more natural-looking piece because it looks as though the strands are coming directly out of your scalp. In addition, the shedding is significantly minimized.
Thin skin was thought to be the best material used for injection techniques however thin skin is like a plastic material and is unable to “breathe” or allow the scalp to properly ventilate. Skin weft is yet another product where the strands are injected. Instead of machine-tied wefts, the hair is injected into a long strip of thin skin which can be adhered to the scalp. The result is undetectable even when parted.
Silk is now the newest base material to hit the market. The strands are injected into this pure Chinese silk. Not only can you have the invisible knot-free strands, it is a 100% breathable material, unlike the thin skin. This new silk material can be used for lace wigs, lace front wigs, frontals, closures, toupee top pieces and best of all, synthetic lace wigs. Since you cannot bleach synthetic fiber knots, injecting the synthetic strands into silk lace is the answer everyone has been looking for.
So, for the answer, due to the versatility and the ability to be undetected, injected strands win with flying colors!
