Neither one has silicone in it which is super important to me since Lacey must have the driest tail in the world because if I spray Show Sheen on it or anything similarly siliconed, it immediately starts breaking all over the place.
I've been using Cowboy Magic on her for some time and while I love it, it's expensive! A 4oz bottle of the Mane 'N Tail stuff is only $3.99 at the store while Cowboy Magic detangler is $8.99 for the same amount.
Both of them say that they condition which is an important detail for me since Lacey has such dry hair.
I just don't want to get the Mane 'N Tail and discover that it gets used up super quickly since my current bottle of Cowboy Magic has lasted me about 2 years with monthly use.
I dunno, it's a quandary. If I had all the money in the world, I'd buy a bottle of Show Sheen since that's great on wet hair and get a 16oz bottle of cowboy Magic detangler too so I had something for every situation. However, at the store that would run me about $40 and I really don't need to, and shouldn't, spend $40 on hair products.
I'll probably just go with the Cowboy Magic, but I thought it wouldn't hurt to ask. :)
Also, if anyone has any other suggestions of reasonably priced awesome detanglers, go for it.
