The maximum mass for a stable white dwarf is around 1.4 M(sun). Since stars of masses up to 8 - 12 M(sun) may form white dwarfs ===> substantial mass loss must occur during the evolution of low mass stars.

"WebThe low-mass stars do not become dramatically redder in their giant phase, so the larger surface area is simply to counter the greater power generation. A solar mass star increases its radius by roughly a factor of 6 as it moves into its giant phase, while its temperature drops by only about 35%. " - Is a red giant a low mass star

WebLow-mass stars turn into planetary nebulae towards the end of their red giant phase. At that point the star becomes highly unstable and starts to pulsate. This produces strong stellar winds which throw off the outer layers of the star. The outer layers drift away from the star leaving a small hot, bright core behind, called a white dwarf.
