Jet Black (1) Thinning Hair Fill-Ins

The Color

Jet Black (#1): Our deepest, darkest black. A bold, true jet black with no brown undertones.

Why You'll Love It

Instantly add extra volume where your hair needs it. Enhance your hair's volume and length with Bombay Hair Thinning Hair Fill-Ins. Whether you're experiencing hair thinning, hair loss, or want extra volume, these fill ins provide natural-looking coverage near the part line and crown. Featuring thin, seamless silicone wefts that lay flat against your head, these fill-ins mimic natural hair growth for a flawless blend, even on the thinnest hair.

Unlike other hair extensions that are single-drawn and thin at the ends, all Bombay Hair clip-in extensions are double-drawn, which means they’re thick from root to tip for a fuller, luxurious look. We use Cuticle Remy hair with 100% of the cuticle intact, helping your extensions stay smoother, softer, and more tangle-resistant while preventing them from drying out too quickly.

How To Install

Longevity & Care

With proper care, your clip-in extensions are designed to last:

• Frequent wear: up to 12 months

• Occasional / special-event wear: up to 2+ years

To get the best longevity, we recommend:

• Brushing gently before and after each wear (use our loop brush or soft bristle brush)

• Always support the weft with one hand while brushing to avoid tension on the clips

• Washing only when needed (about every 15–20 wears) with sulfate-free shampoo and hydrating conditioner

• Deep condition hair once every 1 to 2 weeks if wearing frequently  

• Letting the hair air dry whenever possible instead of using high heat

• Always apply a heat protectant before styling with hot tools

• Storing your extensions in a storage bag/carrier or on a hanger in a cool, dry place, with clips closed

Color Match Help

Our extensions are dyed with multi-dimensional color, so they’re made to blend seamlessly with your hair – even if your shade is slightly off.

• Multi-dimensional, natural-looking color is designed to blend with highlights, lowlights, and balayage.

If you’re unsure on shade, you can:

• Get a free color match by sending us photos.

• Order color swatches to compare shades at home before committing to a full set.

• Take our hair quiz to quickly find your best match.

You can also mix and layer shades (for example, a slightly lighter and slightly darker tone) for a custom, salon-style blend.

Tip: Check your hair color in natural daylight, focusing on mid-lengths to ends, when choosing your extension shade.
