Hair

So im a guy, I straightened my hair the other day, and I want to know what i can use so it doesnt look so damaged and dry and obvious that its been straightened.

when i come out of the shower and my hair is wet it looks good, and when i gel it right afterwards it looks good too until the wetness goes away and its not black anymore. it turns brownish and looks dry and bad.

anyone know what i can use to help it? any help at all would be appreciated

thanks
brett
