DON COSA completely ruined my hair. my hair was just stuffed under a really expensive wig. They pulled and tugged on my hair so much, it ripped all my hair out. They lie and scam, and went i went there for the consultation, i knew i should have been weary. they did nothing but bash the competition. they bad mouthed other companies so much. If a company has to bad mouth its competition so much, and not rely on the integrity and quality of their product alone...there's a big problem. BUYER BEWARE OF DON COSA! They will also tell you that the competition is the reason they have bad reviews on the internet - that it's the competition writing all these complaints. It's not. It's real people, like me, who have been utterly screwed.
