If you’ve ever thought your horse or pony has a better selection of grooming and pampering products than you, you’re not wrong.

Mane ‘N Tail — a shampoo produced for our equine companions — is now the number one best selling hair care product on Amazon, overtaking brands including L’Oreal.

The shampoo and conditioner have long been a celebrity favourite — Hollywood actress Jennifer Aniston has been championing the brand for years.

But now at just £7.23 for the shampoo and conditioner, mere mortals are getting in on the pony pampering too — Mane N Tail has reportedly seen a sales increase of a whopping 175% this year.

The products were originally “specifically targeted for show horses with long flowing manes and tails”.

Manufacturers Straight Arrow claims the products “help to maintain and achieve long, luxurious, thicker, fuller, healthier-looking hair.”

As well as shampoos, conditioners, detanglers they come in herbal versions and even anti dandruff formulas.

“Our original formula Mane ‘N Tail Shampoo and its companion conditioner have been a best kept secret for beauty aficionados everywhere,” said Devon B. Katzev, president of Straight Arrow.

The products reportedly took off after owners took a sneaky trial of their equine’s hair care — maybe jealous of their flowing locks.

“They told their friends, and then the word spread like wildfire,” added Mr Katzev.

The shampoo formula contains “high lathering and ultra-cleansing agents” that are “fortified with moisturisers and emollients to help leave hair soft and ultra clean”.

H&H reader Hannah Wallis from London isn’t surprised by the products’ rocketing popularity.

“I’ve been a big fan for a few years — when I started using it, my hairdresser commented that my hair had improved in condition, which is enough to keep me using it,” she said.

“My fiance found it a bit disconcerting that the bottles have instructions for equine use, but he’s come round to it: I’ve even caught him stealing the conditioner on occasion (although his hair is very bouncy these days…)!”
