Evans and her husband became part owners of their favorite club, which is where she says she lost her remaining inhibitions. She became a stripper and pole Dancer and began considering modelling work. Due to a scar from an appendectomy she thought that she would not get magazine work, and therefore went into the porn industry at age 21. She entered the adult film industry on March 24, 1998, and did her first scene with Mr. Marcus in the film Real Sex Magazine 11. She initially used the mononym Alana, which was derived from her former husband's name, Alan. She added the last name Evans to her stage name a few years after debuting in porn. Her agent at the time was Reb Sawitz of Pretty Girl International. She signed with agent Shy Love on May 7, 2012.
Evans had a biracial son shortly before her eighteenth birthday. She married pornographic actor Chris Evans in November 1999.
To date Evans has starred in over 450 films, including numerous Playboy TV projects and 30 softcore movies. She also hosted a segment on KSEX radio called All in the Porn Family until June 2005 as well as hosting a show for Playboy Radio called Private Calls, which airs on the Sirius Satellite Radio Network. She is also the host of the Spice Radio program All Wives Cheat on Sirius XM 103.
In September 2006, Alana and Chris Evans created a porn production company called CreamWorks Films. The studio's first film, Pick 'Em Young, featured Alana performing with 18-21 year old new male performers that were recruited through Myspace. Alana focused on producing and casting while Chris focused on directing and editing.
Never fully satisfied with her bust size, Evans vacillated between the idea of surgical enhancement and accepting her image as a natural starlet. At one point she declared "they are going to stay real... I don't want plastic in my body." In late 2007, Evans had her breasts enlarged to DD.
In November 2008, Alana and Chris Evans launched another production company, Royalty X Films. The company's first film was Super Pink Holes.
In 2012, Evans made her professional singing debut with the song "Pop That Tooshie," which is the lead single from the Lords of Acid album Deep Chills. In June 2014, she released a song titled "Make You Love Me."
In February 2014, Evans began writing a column titled "The Stoned Gamer" for High Times magazine.
On January 16, 2018, she stated on The Today Show that she supported Bernie Sanders during the 2016 election.
