If I start to use women's Rogaine, will my hair become fuller and restored?

If you have trichotillomania, no medications for hair growth will help.  You need to treat the trichotillomania before treating hair loss.

Rogaine is very useful in female pattern hair loss.  It is not useful in trichotillomania.  You may be able to regrow hair through a transplant of follicles, but most physicians will not offer this solution because trichotillomania tends to be a recurrent condition and the individual resumes pulling out their hair.  Psychological intervention is the best initial treatment followed by avoidance of pulling out hair follicles.  It is a difficult condition to treat and extremely difficult to cease.  After years of pulling, the follicles tend to be permanently lost so the sooner you stop pulling out your hair, the more likely you are to spare yourself from permanent hair loss.  

It will only be possible to assess regrowth potential after getting all your medical history and examining your scalp up close. Here are some general points:Trichotillomania is not always regrowable. If hair pulling happens for a few weeks and then there is no pulling for a few weeks or months, hair can recover. If hair pulling goes on for an extended period of time (more than a few months), scar tissue can develop under the skin due to repeated injury to the hair follicle. This scar tissue prevents full regrowth no matter what treatment is administered. A biopsy is not usually needed but can confirm such scarringRogaine is FDA approved for genetic hair loss but not trichotillomaniaIf hair pulling has happened recently, then Rogaine can sometimes be used off label to stimulate injured and damaged follicles to grow. Anyone considering such use should speak to their physician. This may not be a good option for everyone. Rogaine will have very little benefit in long standing trichotillomaniaOptions for improvement in long standing and stable trichotillomania include hair transplantation, hair pieces, wigs.
