Broke proximal phahux toe how long to heal ?

Depends: Was there any dislocation or mal alignment. How is it being treated. Best guess, 6 weeks.

6-8 weeks: Is the approximate time. For a toe, make sure when you walk the digit is protected. The propulsive phase of gait will put pressure on the toe which could reinjure or delay healing.

4-8 weeks: Becomes less painful in 2-6 weeks xrays heal in 4-8 weeks the swelling may last for months.
