Jet Black (1) Thinning Hair Fill-Ins

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

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.

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

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.

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.
