Is it worth buying a specific "horse shampoo"? My aunt works for a company that makes soap so I usually just use whatever she has extra of or I buy the cheap shampoo and conditioner from Walmart. What about detangler/hair growth product? Walmart has Mane N Tail shampoo and conditioner cheaper at Walmart than I can find online so I was wondering if I should continue purchasing cheap human products or purchase Mane N Tail. Thoughts? Or other brand ideas? And here's a picture of Rock because he's cute!
