Hello, Losing up to 100 strands/day is completely normal and is a sign of normal hair cycle. But receding hairline and frontal baldness is a sign of androgenic alopecia. There are many medications oral and topical available which can help in receding hairline but re growth can be tried by prp mesotherapy and microneedling. At least 6 sessions required to see the desired results. If that doesn't work then the only option left is hair transplant and scalp micro pigmentation if there is patchy hair loss or scanty growth in future

10-20 strands is very normal. But receded hairline can be treated with hair transplant as there are no more roots to be grown by medicine.
