These days Tom Cruise has more than just a fleeting film career to worry about.

The former sex symbol is losing his signature dark locks!

The 46-year-old Tom is struggling with serious hair woes as he watches his once luxurious mane become increasingly thinner with each passing day, Star Magazine insiders have revealed.

A source says: “Tom is using Rogaine because his [hair] is thinning. Plus he gets weekly massages to stimulate growth.”
