I’ve recently purchased the dark brown slim pony and the thickness was a great match to my hair and very realistic looking once my hairdresser put some long layers in and died same colour as my own hair. PHair is luscious and soft to touch. My only feedback would be a suggestion to make the dark brown hair more dark as it’s more of a medium mousy brown. And the next colour range is black which is way too dark. A rich chocolate brown, a true dark brown needs to be added to the range! Overall 10-10 super happy with my purchase
