Pantene, smooth and sleek. But only on special occasions as it's quite expensive. I would add that my bloke was only ever shown or competed "natural", so if you needed to plait - the hair might be a bit too soft!
Yep! I always use budget supermarket human shampoo and conditioner on mine - my own hairdresser told me long ago that the cheaper the shampoo, the milder it usually is. Never had an issue with either but if you are worried, just do a patch test first.
I don't think I have ever used equine shampoo conditioner on my horse and never had a problem. They are so well tested for allergens etc in human grade you will probably get a better quality product by using Alberto balsam at £1 a bottle than gallop etc at about 10 x the price
When I worked as a hunt groom we had too many horses to do so bought cash and carry big containers of washing up liquid, it always cleaned them up lovely and they shone beautifully at the meet. I used cheap conditioner on the tails but never used conditioner on the mane or we wouldn’t have got the plaits to stay in 😂
