Before assuming hair loss is purely genetic or stress-related, it's worth asking a more basic question: is your diet actually giving your hair what it needs to grow? Nutritional deficiencies are a more common, more overlooked cause of hair shedding than most people realise — and it's a gap products like GreenKare Hair Regaining are specifically designed to help address.
Iron deficiency is a well-documented, underdiagnosed cause
Low iron (ferritin) levels are consistently linked to increased hair shedding, particularly in women, and can occur even without full-blown anaemia — a simple blood test can identify this, and it's a more common finding than most people expect, especially in Singapore among women who menstruate heavily or follow plant-forward diets.
Protein and zinc are foundational, not optional
Hair is almost entirely made of a protein called keratin, so genuinely inadequate protein intake (common with restrictive dieting) directly limits what your body has available to build new hair. Zinc plays a supporting role in hair tissue growth and repair, and deficiency has been specifically linked to hair loss in clinical literature.
Crash dieting is a specific, common trigger
Rapid, severe calorie restriction is a well-recognised trigger for telogen effluvium — your body deprioritises hair growth (a non-essential process) when energy intake drops sharply, redirecting resources to more critical functions. This is part of why hair shedding sometimes follows a few months after a crash diet or bariatric surgery.

Iron, zinc, and protein deficiencies are genuine, well-documented, and often overlooked causes of hair loss — worth ruling out with a simple blood test before assuming any shedding is purely genetic. Getting the nutritional basics right matters most; daily support like GreenKare Hair Regaining can help fill the rest.
