The horse mane is the long growth of hair running along the top of the neck, from the poll (just behind the ears) down to the withers. It is one of the most visually distinctive features of a horse and varies enormously between breeds — from the long, flowing mane of an Andalusian or Friesian to the short, upright crest of a Przewalski’s horse. Beyond its aesthetic role, the mane serves practical functions in nature and is a significant part of show preparation in the ridden disciplines.
Function of the Mane
The mane evolved primarily as protection. In the wild, it shields the crest of the neck from biting insects, provides some insulation against cold and rain, and may offer a degree of protection in fights between stallions, where the neck and crest are a target. The forelock — the section of mane that falls forward over the face — protects the eyes from flies and sun.
In domestic horses, these functional benefits still apply, though the management of the mane is usually driven by discipline requirements, breed standards, and the owner’s preference.
Breed Variation
Mane type varies significantly by breed and is often a defining characteristic:
- Iberian breeds (Andalusian, Lusitano) — thick, long, and often wavy or slightly crinkled. Traditionally worn long and loose.
- Friesian — exceptionally thick, long, and luxuriant. Friesians in competition are usually presented with the mane loose and flowing as a breed hallmark.
- Thoroughbred — fine and silky, usually manageable in length. Thoroughbreds in race training typically have the mane pulled short for practicality.
- Cob and draught breeds — coarser and often very thick. Frequently plaited for showing.
- Mountain and moorland ponies — thick, often double-sided (falling both ways), with excellent natural weatherproofing. These breeds are shown with a full, natural mane as part of their native type standard.
Mane Care and Grooming
Regular grooming is essential to keep the mane clean, tangle-free, and in good condition. Key practices include:
- Brushing or combing — use a wide-toothed comb or dandy brush, working through the mane from the ends upward to avoid breaking hair unnecessarily. Detangling spray or a small amount of mane conditioner makes this considerably easier, particularly in horses with thick, curly, or frequently tangled manes.
- Washing — the mane should be washed with a suitable horse shampoo when dirty or greasy. Frequent washing can strip natural oils and lead to dryness; once or twice a month is typically sufficient outside of intensive show preparation.
- Mane pulling — in many disciplines, the mane is pulled (thinned and shortened) to a standard length of approximately 10–13 cm (4–5 inches) that makes plaiting easier. Pulling involves removing hair from the underside of the mane by back-combing and pulling out small amounts. It is done gradually over several sessions to avoid soreness. Many horses tolerate it well; a small number find it uncomfortable, particularly in cold weather when the skin is less pliable. Scissors should not be used to cut the mane to length — this creates a blunt edge that does not lie flat and is obvious to judges and experienced horsemen.
Plaiting for Competition
In most English disciplines — dressage, show jumping, showing, and eventing — the mane is plaited for competition. Plaits should be small, even, and lying flat against the neck on the right-hand side. The number of plaits is traditionally odd (seven, nine, or eleven) for mares and geldings; an even number for stallions, though this tradition is not universally observed. Plaiting is typically done on the morning of the competition using thread or rubber bands, though professional grooms at top events often plait the night before and use a fine hairnet over the finished plaits to protect them overnight.

Frequently Asked Questions
How do I encourage my horse’s mane to grow?
The primary driver of mane growth is genetics — some horses simply grow better manes than others. That said, several practical steps help. Keep the mane free of tangles to prevent hair breakage. Use a detangling conditioner or mane-and-tail spray regularly. Avoid excessive washing, which strips oils. Ensure the horse’s diet is nutritionally complete, with adequate protein, biotin, and zinc — deficiencies can affect coat and mane quality. Some owners use a mane and tail growth serum; the evidence for these products is largely anecdotal, but keeping the mane moisturised and protected from rubbing does help retain length. A horse that rubs its mane on fence posts or stable doors is likely doing so due to skin irritation (sweet itch, lice, or dry skin) — address the underlying cause.
Should the mane fall to the left or right?
By convention in the UK and most of Europe, the mane falls to the right-hand (off) side of the neck. This is the standard expected at competitions. In practice, many horses naturally prefer to carry their mane to one side due to how they rested as foals, and training it to the “correct” side requires consistent grooming and, often, a light rug or mane tamer worn overnight. If a horse persistently wants to carry its mane to the left despite training efforts, a light application of water and laying the mane flat each day will gradually correct it over a few weeks.
What is sweet itch and how does it affect the mane?
Sweet itch (summer seasonal recurrent dermatitis) is an allergic reaction to the bites of Culicoides midges, which are most active at dawn and dusk from spring through autumn. Horses with sweet itch rub intensely along the mane, tail, and belly, often to the point of breaking and thinning the hair and causing raw, thickened skin. Management involves reducing midge exposure through purpose-made sweet itch rugs (fine mesh fly rugs that cover the neck and belly), stabling at high-risk times, applying insect-repellent products regularly, and in severe cases, veterinary treatment with corticosteroids. The British Horse Society has detailed guidance on managing sweet itch.
