What should doctors do if they lose too much weight and experience excessive hair loss? Will it continue to grow

Excessive weight loss can lead to regrowth of hair loss, which can be improved through adjusting dietary structure, supplementing nutrition, reducing stress, medication treatment, laser therapy, and other methods. Hair loss is usually caused by malnutrition, hormonal imbalances, hair follicle damage, chronic diseases, genetic factors, and other reasons.

1. Adjusting dietary structure

Hair loss may be related to insufficient protein intake. Excessive dieting during weight loss can lead to a lack of high-quality protein in the body, causing hair follicles to be unable to synthesize keratin normally. It is recommended to take eggs, fish, soybean milk and other foods every day and supplement essential amino acids. When there is insufficient nutrition, symptoms such as dry and easily broken hair and increased scalp oil may occur.

2. Supplementing nutrition

Lack of trace elements such as iron, zinc, and vitamin D can hinder the hair growth cycle. Moderate consumption of foods rich in trace elements such as pig liver, oysters, mushrooms, etc., or taking compound ferrous sulfate folic acid tablets, zinc gluconate oral solution, vitamin D drops, and other medications according to medical advice. Excessive deficiency may be accompanied by symptoms such as cracked nails and pale skin.

3. Reduce stress

Long term mental stress can lead to an increase in the proportion of hair loss during the resting period. It is recommended to relieve stress through meditation, yoga, and other methods to ensure 7-8 hours of sleep per day. When the body is in a state of high stress, circular patchy hair loss, scalp tightness, and other conditions may occur.

4. Drug treatment

Androgenic alopecia can be treated with minoxidil ointment according to medical advice to promote hair follicle blood circulation, or finasteride tablets to inhibit dihydrotestosterone conversion. Patients with alopecia areata may require acetate prednisolone tablets to regulate immune responses. The use of medication may cause adverse reactions such as scalp itching and hirsutism, and regular follow-up visits are necessary.

5. Laser therapy

Low energy lasers can improve the hair follicle microenvironment through photobiological stimulation and are suitable for use in combination with drugs. Laser hair growth cap or comb treatment is required at a professional institution, usually lasting for 3-6 months. Transient scalp redness may occur after treatment, which usually resolves on its own. During weight loss, the daily calorie intake should not be less than 1200 calories, and the safe range for weekly weight loss should not exceed 0.5-1 kilograms. After hair loss, it usually takes 3-6 months for new hair to grow. During the recovery period, avoid frequent dyeing and perming of hair. When combing hair, choose a wide toothed wooden comb. If hair loss persists for more than 6 months or is accompanied by scalp abnormalities, it is recommended to seek timely diagnosis from a dermatologist for hair follicle testing.
