Pop Punk had an influence on Glam Metal. I think that music genres are iterative things, they build and innovate on each other to create new genres, and while Glam Metal is obviously different from Pop Punk it is easy to listen to songs from both genres and notice some similiarities.
Pop punk most definitely had an influence on the glam metal of the 1980's. Metal bands started to incorporate slower paced love ballads into their songs which was a direct result of pop punk. Metal bands also incorporated some of the punk look by having the ladies dress in fluorescent colors. Both fashion and music were influenced.
Rock music is a huge blob of which each little piece inside of it feeds off every single other piece. Pop punk was certainly an influence on the 1980s glam metal scene, almost all aspects of it. Especially when it came to the showmanship involved, and also possibly the makeup and hairstyles.
No, I do not think that pop punk had an affect on the glam metal of the 1980s. Bands back in this time just found a sound that the people liked, and adapted to it. These to types of music came about in two different ways, and are two seperate types.
Pop-punk emerged in the mid-1970's as a descendent of proto-punk acts (like MC5, The New York Dolls, The Velvet Underground, David Bowie, and T. Rex) and power-pop acts (like The Beatles, The Byrds, The Who, and Badfinger). The most-notable early pop-punk band would be The Ramones, who were inspired by many of the acts listed above and other acts associated with the proto-punk and power-pop scenes, both of which existed from the mid-to-late 1960's to mid-1970's. Pop-punk evolved as a genre and The Ramones would be contemporaries of many similar acts, such as Buzzcocks, The Undertones, Generation X, and The Jam. In the late 1970's, Bad Religion formed and ushered in the next phase of the pop-punk movement, the "hardcore" movement. They would be considered contemporaries of bands like T.S.O.L., Social Distortion, The Vandals, Guttermouth, and The Descendents. It was at this point, "emo" began popping up, containing acts like Rites of Spring, Fugazi, and Husker Du.
Glam Metal, on the other hand, evolved during the late-70's through late-80's as an extension of arena rock acts and glam acts from the 1970's, such as Aerosmith, The New York Dolls, Boston, Kiss, and Cheap Trick.
So, it's not that pop-punk was an influence on 80's Glam metal, but that both scenes shared a similar genre from yesteryear as an influence: proto-punk.
Pop punk did not have an influence on the glam metal of the 1980s. Glam metal actually started in the 70s and grew more popular during the 80s. However, pop punk was mixed in there but they did not intertwine with each other. So I do not think pop punk had any influence.
The 80's glam metal scene was mainly influenced by the glam scene of the 70's. Believe it or not, there were glam rock bands coming out in the 70's. Slade, Sweet, etc. Then came Motley Crue and Hanoi Rocks. They ultimately started 80's glam metal. Then came Poison, Ratt, Warrant, etc. Now, I don't know if any particular band or individual was influenced by punk, but glam metal has a whole was not.
