If you file Head of Household with a child who is 23, a student & a dependent can you lose that HOH status if your child earns money? Wondering for Federal & California.

It seems that California has a $4700 earnings limit but not sure about the limit for Federal taxes.  If for example my college student child earned $5000 would that disqualify me from Head of Household status for both Federal and State taxes? (California being the state).  Thx
