Dull hair can often be reversed, which is great news for those dealing with this common concern. Before diving into solutions, it's important to understand what causes dullness in the first place.
Why is this important?
Much like split ends and frizz, dullness can often be prevented. Learning about the science behind dull hair and how it happens is the first step to addressing it and boosting shine from the inside out.
What causes dull hair?
Dullness, like other hair issues, stems from cumulative damage. This damage can result from chemical treatments, frequent use of heat styling tools, or environmental exposure to UV rays and pollution. These factors compromise the hair’s structure, which includes up to three layers: the cuticle, the cortex, and in some cases, the medulla.
The cuticle, which is the outermost layer of hair, acts as a protective shield for the inner cortex. When the cuticle is healthy, hair looks smooth and shiny. However, when the cuticle is damaged, the cortex becomes exposed, leaving hair vulnerable to problems like dullness, breakage, frizz, and split ends.
When the cuticle wears down, it no longer protects the hair’s internal structure, including the system of keratin chains and bonds in the cortex. This damage impacts hair's properties, leading to breakage and a dull appearance. In contrast, a smooth, intact cuticle reflects light, making hair look shiny, while a damaged cuticle scatters light, causing it to appear dry and lackluster.
Can dull hair be fixed?
While prevention is always ideal, reversing damage is possible with the right products. Advanced hair care solutions, like K18’s patented biotech, can help repair damage and restore shine.
The K18PEPTIDE™, found in products like their leave-in molecular repair mask and molecular repair hair oil, works to smooth the hair and protect it from future damage. These treatments also help boost shine and improve the overall vibrancy of hair over time.
The leave-in mask works on a molecular level to repair damage caused by bleaching, coloring, chemical treatments, and heat styling—all in just four minutes. With continued use, hair becomes stronger, softer, smoother, and more resilient.
K18’s hair oil also targets deeper damage, helping to repair dull hair while increasing shine by over 100% and reducing split ends by nearly 80%. Additionally, it provides 24-hour frizz control and protects hair from heat up to 450°F.
