The element hydrogen makes up about 74.9% by mass of the sun, and helium makes up about 23.8% of the mass of our local star. (That leaves about 1.3% other elements in the sun's mass.) As the mass of the sun is approximately 1.9891 x 1030 kilograms, an investigator has a bit of math to do to discover the actual mass of hydrogen and helium that make up the sun, if that is what is actually desired. A link is provided below for comfirmation and further investigation.
A helium flash occurs in low-mass stars during the helium burning phase. High-mass stars do not experience a helium flash because they have a higher core temperature and pressure, so helium burning begins smoothly without the need for a sudden ignition event. Additionally, high-mass stars have higher energy production rates, which prevent the conditions required for a helium flash from occurring.
Stars contain hydrogen, helium and a little iron.

Most stars, particularly in their core, are made mostly of hydrogen and helium. These elements are the most abundant in the universe and are the building blocks of stars through nuclear fusion reactions.
The second lightest and second most abundant element found in stars, making up about 25% of the Sun, is helium. Helium is formed through nuclear fusion in stars, with hydrogen being the most abundant element in stars like the Sun.
All stars contain hydrogen and helium.
Stars are made of hydrogen and helium.
Helium exists because Hydrogen fuses into Helium in the core of hot stars.
Yes, stars fuse Hydrogen atoms to make Helium in a natural process.

Helium
As a star ages, it fuses hydrogen into helium in its core. Therefore, helium becomes more abundant in older stars compared to younger stars.
Stars are mostly composed of hydrogen and helium.
All red giant stars will start helium fusion when their core is compressed.
