The Truth About Kolinsky Brushes: A Conversation with Industry Experts

When it comes to high-quality nail brushes, Kolinsky brushes are often considered the gold standard. But what exactly makes a Kolinsky brush so special, and is that "100% Kolinsky" label really accurate? We sat down with industry experts to uncover the truth behind these sought-after tools.

Question 1: Is a brush labeled as “100% Kolinsky” truly 100% pure?

Expert & Manufacturing Response: No, not quite. Nearly all manufacturing companies incorporate some nylon fibers into their brushes, even when labeled as "100% Kolinsky." The reality is that it's rare to find a brush that's truly 100% pure Kolinsky.

Question 2: Why isn’t there more transparency from manufacturers about this?

Expert & Manufacturing Response: There’s no mandate for manufacturers to disclose the exact composition of their brushes. The allure of the "Kolinsky" brand name drives sales, so even using just a single strand can warrant the name. This lack of regulation allows companies to market brushes as 100% Kolinsky, even when they aren't.

Question 3: How can customers ensure they’re getting a genuine 100% Kolinsky brush?

Expert & Manufacturing Response: It’s important to note that a brush with 75% or more Kolinsky content is generally considered high-quality. The difference between 90% and 100% Kolinsky is subtle, with the main distinction being the cost. To balance quality and affordability, many manufacturers add nylon fibers.

Question 4: Why would someone choose a 75% or even 60% Kolinsky brush over a 90% one?

Expert & Manufacturing Response: A 90%-95% Kolinsky brush is incredibly soft and highly flexible, which can be ideal for certain techniques. On the other hand, a 75% Kolinsky brush maintains softness but offers a firmer stance. The preference often depends on what the nail technician has become accustomed to at the beginning of their journey.

Question 5: Does the year of production affect the quality of Kolinsky brushes?

Expert & Manufacturing Response: Absolutely. Just like wine, there’s a distinction in quality based on the vintage or year the hair was acquired. The diet of the animal and the environmental conditions play a significant role in the quality of the hair produced. Unfortunately, many manufacturers overlook this, resulting in lower-quality Kolinsky hair fibers that are more prone to breaking.
