How to Tie a Hair Rig

By Alex Clayton · Updated 23 October 2026

A hair rig mounts the bait on a short length of line, the “hair”, that comes off the hook shank instead of putting the bait on the hook itself. A feeding carp can suck in the bait without feeling the hook, and when it tries to blow the bait back out, the bare hook turns and catches in the bottom lip. That is why the hair rig is so widely used for carp on bottom baits.

Guides online disagree on turn counts and lengths, so this one gives starting ranges, says where sources differ, and shows you how to test the finished rig. Seven steps take you from a spool of coated braid to a simple hair rig for carp, ready to clip to a lead or a method feeder. The whipping in Step 5 is the knotless knot.

The kit list is short, and none of it has to be a particular make. Lay it all out before you cut anything.

  • Hook: a wide-gape pattern. Size 6 is a common starting point, with a size 8 for smaller baits.
  • Hooklink: coated braid, which you strip back to form the hair and a supple section behind the hook.
  • Baiting needle: to pull the hair loop through the bait.
  • Hair stops: small plastic stops that hold the bait on the loop.
  • Braid scissors: a sharp pair cuts braid cleanly, where blunt household scissors can fray it.
  • Practice bait: a 15mm bottom bait or wafter. See our best baits for carp for hookbait options.

Choose the hooklink coating by the lakebed. A stiffer coating helps the hooklink kick away from the lead and resist tangles, while a softer one lies better over a dirtier bottom. Check the hook point is sharp straight out of the packet, because you will test it again in Step 7.

By now you should have the kit on the mat and the hook checked. If you only buy one hook pattern to start, make it a size 6 wide gape.

How much coating you strip decides how long your hair can be, so match it to the bait before you start. Getting this right first saves tying the whole rig twice.

  1. Cut 10 to 12 inches (25 to 30cm) of coated braid. Be generous, because the hair, the knot and the end loop all use up line.
  2. Strip the coating from one end with a thumbnail or a stripping tool.
  3. Strip to the length that suits your hookbait, using the table below.
Hookbait Stripped length (starting point)
Bottom bait About 3in (7.5cm)
Pop-up About 4in (10cm)
Snowman About 5in (12.5cm)

The stripped braid does two jobs. It forms the hair itself, and later it gives you the short, supple hinge in front of the hook eye that lets the hook turn (Step 5). Strip too little and you run out of soft braid for the hinge.

Milestone: hooklink cut, end stripped to the length for your bait. A single bottom bait needs the shortest strip; a snowman needs roughly two inches more.

Step 3: Tie the Hair Loop and Mount the Bait

Put the bait on before you tie the hook. The gap between bait and hook depends on the size of the bait, and you can only set it accurately with the real bait in place. Set it against a bare hook and the hair usually ends up too long or too short.

  1. Fold the stripped end back on itself and tie a small overhand loop, about 5mm across. Keep it just big enough to pull a hair stop through.
  2. Trim the tag end close to the knot.
  3. Push the baiting needle through the centre of the bait.
  4. Catch the loop on the needle’s hook and draw it back through the bait.
  5. Push a hair stop through the loop, then slide the bait down so it sits snug against the stop.

Two small baits, or a boilie topped with a piece of artificial corn, can share one hair. Allow a longer strip in Step 2 if you plan to fish them this way.

The bait should now be sitting on the loop, held firm by the stop.

Step 4: Thread the Back of the Eye and Set the Hair Length

This step settles two things: which way the line goes through the eye, and how far the bait hangs from the hook. Guides rarely agree on the second.

  1. Pass the free end of the hooklink through the back of the hook eye, from the point side to the shank side. This keeps the hooklink coming off the shank side, so the hook sits naturally and can turn when a fish tests the bait.
  2. Slide the hook along the line until the bait hangs just off the bend.
  3. Set the gap between the bend of the hook and the bait.

Sources differ on that gap. One gives 8 to 10mm; another says about one bait width. Use either as a starting range to adjust and test.

Bait Starting gap Note
Bottom bait 8 to 10mm, or about one bait width The standard starting point
Wafter 8 to 10mm, then test Its buoyancy offsets the weight of the hook
Pop-up 8 to 10mm, then test Needs putty or shot on the hooklink to balance it
Snowman 8 to 10mm, then test Uses the longer 5in strip from Step 2

Milestone: hook positioned, bait hanging just off the bend. A hair that is too long can lead to missed takes and poor hook holds, so shorter rather than longer is the safer mistake.

Step 5: Whip the Knotless Knot Down the Shank

One guide says 6 to 8 turns, another says 7 to 9. The exact count matters less than turns that sit tight, flat and side by side.

  1. Hold the hair flat against the inside of the shank at the gap you set in Step 4.
  2. Whip the hooklink down the shank towards the point in tight turns. Most sources land between 6 and 9.
  3. Come back up the shank with 2 or 3 turns over the top.
  4. Pass the tag end back through the eye, the same way as before (point side to shank side).
  5. Wet the turns and pull tight.

Leave about 10mm of stripped, uncoated braid in front of the eye. This short hinge lets the hook turn in the fish’s mouth, and it is why the strip in Step 2 has to allow for more than the hair alone.

For the full breakdown, follow our step-by-step knotless knot guide.

Milestone: knot bedded, hinge visible, hair still the right length. Whipping can drag the gap, so recheck it, and retie if it has moved.

A loop on the free end turns your hair rig into a quick-change component you can swap on the bank without retying.

  1. Measure the finished hooklink. Sources range from about 6in to 10in (15 to 25cm) for a lead set-up.
  2. Tie a figure-of-eight loop in the tag end.
  3. Moisten the knot, tighten it, and trim the tag.
  4. Attach the loop to a swivel or quick-change clip.

The same hair rig works beyond the classic lead clip. On a method feeder rig, the hookbait usually sits on a hair rig with a shorter hooklink. For lead clips, inline leads and the other common hair rig set-ups, see our carp rigs guide.

Your rig should now be attached and ready to test. A lead clip takes the hooklink at full length; a method feeder needs it shorter.

Step 7: Test the Rig and Fix the Common Faults

Bleeps and no fish, or a rig that comes back in a bird’s nest. A two-minute check before you cast catches several of these faults.

The turning test. Pull the hooklink slowly over the palm of your hand. The hook should flip over and catch the skin. If it slides across, use the table below.

The sharpness test. Drag the hook point lightly across your thumbnail. If it skids rather than digs in, change the hook.

Symptom Likely cause Fix
Hook won’t turn in the palm test Hinge too short, or hair too long Leave about 10mm of hinge; shorten the hair
Missed takes or lost fish Blunt hook, or hair too long Change the hook; shorten the hair
Hooklink tangles on the cast Hooklink too supple Use a stiffer coating or strip less
Pop-up not sitting right Bait not balanced Add putty to the hooklink

An optional line aligner (shrink tube over the eye) also helps the hook turn.

Two legal points apply in England and Wales. You must not keep a fish that is foul hooked (hooked anywhere other than the mouth or throat), and it must be returned alive. Lead weights must be 0.06g or less, or over 28.35g (1oz), so balance a pop-up with putty or non-toxic shot. Both rules are on the GOV.UK tackle rules page.

If a rig fails either test, retie it rather than cast a rig you doubt.

Frequently asked questions

Which way does the line go through the hook eye on a hair rig?

Through the back of the eye, from the point side to the shank side. This keeps the hooklink coming off the shank side, so the hook sits naturally and turns freely. See Step 4 above for the full breakdown.

What size hook should I use for a hair rig?

A size 6 wide-gape hook is a common starting point for a hair rig. Drop to a size 8 for smaller baits. Match the hook to the bait so the bait still hangs clear of the bend, and see Step 1 for the rest of the kit.

Do I have to use barbless hooks?

The national GOV.UK tackle rules for England and Wales do not mention barbless hooks. Many fisheries set their own hook rules, though, and local byelaws can apply. Check the fishery rules and the Environment Agency local byelaws for the water before you fish.

Do I need a licence to fish with a hair rig?

The licence depends on where you fish, not the rig you use. In England and Wales you need a rod fishing licence to fish for freshwater fish with a rod and line, including on private lakes and club waters. Scotland and Northern Ireland have different rules. Our fishing licence guide covers each nation; check GOV.UK for current prices.
