1B Hair Color vs. 1 Hair Color: Understanding the Differences

When choosing the right black shade for your hair, terms like 1 and 1B hair color often confuse. While both may look similar at first glance, they differ in undertone, intensity, and overall effect. This makes understanding the difference between 1B vs. 1 hair essential before committing to a color.

Whether you’re dyeing your natural hair, buying a wig, or selecting extensions, knowing the key differences between these two shades can help you achieve the right look. In this article, we’ll break down the black hair color guide, explaining how 1B hair color vs. 1 hair color truly differs, and how to make the best choice for your needs.

What Is 1 Hair Color?

1 hair color is considered the darkest black shade available on the hair color chart. It is known as jet black hair, and it contains deep blue undertones that make it appear bold and striking. This shade reflects very little light and gives off a dramatic, cool-toned appearance.

Because of its intense hue, shade 1 is popular among people who want a sleek, edgy finish or are matching synthetic wigs. However, for some individuals, especially those with warm undertones in their skin, this color may look too artificial or harsh. It’s best used when aiming for high contrast or full black coverage in your hair transformation.

What Is 1B Hair Color?

1B hair color, also called natural black, is the second darkest shade on the hair shade chart. Unlike the stark blue-black tone of shade 1, 1B contains brown undertones, giving it a softer, more realistic look. This is the natural color you often see in people with naturally black or dark brown hair.

1B is also the most common color found in hair extensions, wigs, and bundles because it blends well with unprocessed hair. If your goal is to create a seamless, natural finish, 1B hair is the ideal choice. It mimics natural hair color and avoids the harsh shine of jet black dye.

Main Differences Between 1B and 1 Hair Color

The biggest difference between 1B and 1 hair color is in their undertones and finish. 1 hair color has cool, blue undertones and offers a strong, ink-like appearance. In contrast, 1B has subtle brown undertones, which give a more natural and versatile look. This difference is noticeable especially under direct light or in outdoor settings.

Another important factor is texture and feel. Many synthetic wigs and weaves in shade 1 may appear stiff or overly shiny, while 1B hair, often left unprocessed, feels softer and more natural. When it comes to black hair shades, 1B wins in flexibility and realism, making it the go-to choice for blending with real hair.

Which Shade Works Best for Different Skin Tones?

Your skin tone plays a big role in deciding whether 1 hair color or 1B will suit you best. Jet black (shade 1) looks striking on cool-toned or pale skin because of the strong contrast. However, it can appear too intense on warmer or medium skin tones, creating an unnatural look in photos and daylight.

1B hair color, on the other hand, complements nearly every complexion. Its natural black tone with brownish undertones adds depth without overwhelming your features. This makes it a preferred option for those seeking a soft black hair color that flatters their face without stealing attention from other elements of their look.

Which One Is Better for Natural Hair Matching?

If you’re wearing hair extensions or wigs, matching them with your natural hair color is essential. Most people’s natural hair isn’t pitch black—it falls closer to 1B. This makes 1B hair color perfect for seamless blending with your leave-out or edges.

1 hair color, though beautiful, is often too dark to match naturally growing hair unless it’s been dyed. That’s why stylists often recommend 1B when you’re mixing weaves or lace wigs with your real hair. It offers a cohesive, natural appearance and avoids the harsh lines where your real hair meets the extension.

Does One Fade Faster Than the Other?

While all black hair dyes tend to be long-lasting, 1 hair color can fade quicker, especially when exposed to sun or frequent washing. The blue-black pigments in jet black are more prone to fading, often turning slightly green or grey over time.

1B hair color tends to hold up better because of its natural undertones. It’s also easier to maintain and refresh without looking too intense. If you’re looking for a low-maintenance black tone that won’t require frequent touch-ups, natural black dye (1B) is the better choice for long-term wear.

Styling & Shine: Which Looks More Realistic?

1 hair color provides high shine and polish, often seen in editorial shoots or fashion campaigns. However, its extra gloss can sometimes give away that it’s a dye or synthetic product. It’s a favorite for people who want to make a bold hair statement.

On the other hand, 1B hair color mimics the texture and light reflection of real hair more accurately. It doesn’t have the same level of gloss as 1 but compensates by looking more believable, especially in daily settings. For a natural-looking finish that still feels rich and beautiful, 1B leads the way.

Which Color Is Best for Wigs and Weaves?

When purchasing wigs or hair bundles, many brands label 1B as their default black because it’s the most common virgin hair color. It blends effortlessly with various textures—whether you’re working with kinky, curly, straight, or wavy hair.

Shade 1, although popular in synthetic wigs, may appear too shiny or stiff in texture. Unless you’re wearing a full wig with no natural hair exposed, 1B offers a better result when realism matters. It matches better with leave-out, blends easily at the roots, and supports heat styling and coloring.
