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. 

Fuller Hair in a Snap.

  • 100% Cuticle Remy human hair

  • Double-drawn: thick from root to tip, not stringy at the ends

  • Seamless, flat-laying wefts for an undetectable blend

  • Available in multiple lengths and gram weights.

  • Mix and match with all our other ranges

  • Can be toned or dyed darker by a professional (bleaching not recommended)

  • Easy at-home application - clip in and remove in minutes 


Each Thinning hair fill-in set includes multiple pieces so you can customize placement wherever you need extra volume. The wefts are designed to lay flat against the scalp while still giving you a natural-looking finish.

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.

If you’re unsure on shade, you can:

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.
