I'm not finding a weed with a light brown flower, but in the garden, you need to mulch heavily to suppress it. If it has a thick root it may take years to eradicate it. Continue pulling or digging and do not allow it to flower or go to seed. Even cutting it off at ground level will weaken it.
In the lawn, use a post-emergent weed killer that won't harm your type of grass. These may help identify it:
