Ray J I'm a Professional Fighter ... of Ingrown Hairs

The death of Whitney Houston hasn't diminished the marketing value of her ex-boyfriend Ray J -- TMZ has learned the singer just inked a major deal ... to fight the war on ingrown hairs.

Ray J is officially the new face of Prince Reigns shaving serum ... and according to the singer's rep, the deal is worth up to $1 million bucks ... though the rep wouldn't divulge the exact terms of the contract.

He went from pudgy to skinny on "Celebrity Fit Club" ... but now Warren G is straight up muscular ... and it's all thanks to his brother, Dr. Dre.

The rapper tells TMZ ... he let himself slide after his stint on the reality show back in 2007 ... but was recently inspired to get his ass back in the gym after a brutally honest conversation with Dre.

“A lot of people in my family have high blood pressure" ... Warren says ... adding, "Dre told me I better start hitting the gym ... so I took his advice."
