Yes, protein deficiency can cause hair loss and thinning because hair is primarily made of keratin, a structural protein. When your body does not receive enough dietary protein, it prioritizes essential organs over hair production. As a result, hair follicles may prematurely enter the resting (telogen) phase, leading to increased shedding, reduced hair density, and brittle strands.
According to Dr Harikiran Chekuri,
“Early identification of nutritional deficiencies is essential before considering advanced treatments. A proper evaluation helps determine whether hair fall is nutritional, hormonal, or genetic.”
How Does Low Protein Affect Hair Growth?
Hair loss caused by protein deficiency is generally reversible once nutritional balance is restored.
- Dietary Adjustment: Focus on high-quality protein sources such as eggs, lean meats, fish, pulses, soy, nuts, and dairy products to rebuild keratin production and support the hair growth cycle.
- Daily Targets: Most adults require approximately 0.8 to 1.2 grams of protein per kilogram of body weight per day, depending on activity level and overall health.
- Timeline: After correcting protein intake, excessive shedding usually reduces within 6–8 weeks, with noticeable hair regrowth appearing in about 3–6 months.
Additionally, other nutritional deficiencies may also impact hair health. For example, inadequate calcium levels can influence overall scalp and follicle function, making it important to assess multiple nutrient factors when evaluating hair loss causes.

When Should You Consult Dr Harikiran Chekuri for Hair Loss Treatment?
You should consult Dr Harikiran Chekuri if hair shedding lasts more than 2–3 months despite dietary changes, or if you notice thinning, bald patches, or a receding hairline. Persistent hair fall may indicate nutritional, hormonal, or genetic causes, and in advanced cases, a hair transplant may be considered for lasting results.
If hair loss is accompanied by scalp irritation or there is a strong family history of baldness, early evaluation is essential. Timely diagnosis helps determine the right treatment approach at our clinic in Hyderabad.
