Clip-In Hair Extensions – Black #1 (US #1B Natural Black)
Description
#1B Natural Black is the shade most people mean when they say "black hair." Indoors it reads as solid black; in daylight a soft brown undertone shows at the ends and along the shine line, with no blue or violet cast. Each set is made from Slavic human hair with cuticles aligned in one direction, so the strands lie flat, reflect light evenly and stay smooth after washing.
What #1B Natural Black Looks Like
The brown undertone is the reason #1B blends with more hair than jet black does. Jet black is uniform and cool, and next to natural dark hair it often looks flat. #1B keeps the depth of black while matching the warmth that most natural dark hair shows outdoors.
On camera and under warm indoor light, the shade stays black. Under direct sun, expect a dark espresso tone at the ends — this is normal for natural black hair and is what makes the blend invisible.
Is #1B Your Shade?
| Your hair | How #1B will look |
|---|---|
| Natural black that looks dark brown in the sun | Exact match |
| Darkest brown that looks black indoors | Close match — wefts sit under your top layer, so the difference disappears |
| Box-dyed jet black or blue-black | May read slightly warmer — send a photo before ordering |
| Black base with brown or caramel balayage | Matches the base; adds depth under the lighter pieces |
| Dark hair with gray at the roots | Matches the lengths; clips sit below the part line and are covered by your own hair |
How to Match the Color at Home
- Use daylight. Stand by a window; bathroom and warm bulbs make all dark shades look the same.
- Compare the mid-lengths and ends, not the roots. Clip-ins blend with the lengths of your hair, which are often lighter than the regrowth.
- Check for undertone. If your hair shows brown in the sun, #1B fits. If it shows blue, it has likely been dyed and needs a photo check.
- Send a photo on WhatsApp taken in daylight without filters, or visit the Beverly Hills showroom at 350 N Canon Drive to compare against the physical set.
Length and Fullness: Choosing Your Set
Every length comes as a 150 g set. The same weight spread over a longer length gives less density per inch: an 18" set produces the fullest result, while a 26" set adds more length with a lighter, tapered finish.
| Length | Approximate fall | One set works for |
|---|---|---|
| 18 inches | Below the shoulder blades | Fine to medium hair; maximum fullness |
| 20 inches | Mid-back | Fine to medium hair; length plus volume |
| 24 inches | Lower back | Fine hair; thick hair usually needs two sets |
| 26 inches | Near the waist | Fine hair; thick hair usually needs two sets |
Fall depends on height and where you place the wefts. For thick, coarse black hair, a second set keeps the ends from looking thinner than your own hair.
Caring for Black Extensions
On dark hair, dryness shows up as lost shine sooner than on blonde. These steps keep the #1B tone deep and reflective:
- Wash rarely. Extensions get no oil from the scalp, so wash only when styling product builds up. Use a sulfate-free shampoo and a moisturizing conditioner from mid-lengths to ends.
- Protect from sun and chlorine. UV exposure oxidizes dark pigment and can shift black toward a reddish tone. Store the set in its bag away from windows, and remove it before swimming.
- Use heat protectant. Curl, straighten and blow-dry as you would your own hair, at moderate temperature.
- Do not lighten. Bleaching black hair lifts it through red and orange and damages the cuticle. If you want a lighter result, choose a lighter shade instead.
FAQ – #1B Natural Black Clip-In Extensions
Is #1B black or dark brown?
Black with a soft brown undertone. It reads as black indoors and shows a hint of brown only in direct sunlight.
What is the difference between #1 and #1B?
#1 is jet black: the deepest, uniform shade with a cool sheen. #1B is natural black: slightly softer, with a brown undertone that matches most natural dark hair.
Will #1B match my dyed black hair?
If your dye is a natural or soft black, yes. Blue-black or jet-black box dye may look slightly cooler than #1B — send a daylight photo on WhatsApp and we will check the match before you order.
Can I color these extensions?
A deposit-only gloss can deepen or cool the tone. Lightening is not recommended: it damages the cuticle and the result is unpredictable.
How many sets do I need?
One 150 g set is enough for fine to medium hair at 18–20 inches. For thick hair, or at 24–26 inches, most clients use two sets for even density from root to tip.
Can I use heat tools?
Yes. Curl, straighten or blow-dry them like your own hair, using heat protectant and moderate temperature.
Are clip-ins suitable for beginners?
Yes. Clip-ins are applied and removed at home in a few minutes, with no salon appointment and no adhesive.
