Can weight loss cause hair loss to heal on its own

Hair loss caused by weight loss can mostly self heal, but it requires timely adjustment of diet and lifestyle. Hair loss may be related to factors such as rapid weight loss and nutritional deficiencies. If accompanied by scalp inflammation or hormonal imbalances, medical intervention is necessary. Short term mild hair loss is usually caused by a sudden decrease in calorie intake or insufficient protein. When the weight loss rate exceeds 5% per month, hair follicles will enter a dormant period due to insufficient energy supply. At this point, restore a balanced diet, ensure a daily intake of 1.2 grams of protein per kilogram of body weight, and supplement with iron and vitamin B foods such as lean meat and spinach. Most people can observe new growth within 3-6 months. At the same time, it is necessary to maintain a regular daily routine and avoid stress reactions caused by excessive dieting and vigorous exercise. Hair loss that lasts for more than six months may involve pathological factors. Abnormal thyroid function can alter the metabolic cycle of hair follicles, manifested as receding hairline or diffuse hair loss. The elevated androgen levels associated with polycystic ovary syndrome can lead to thinning and softening of hair. This type of situation requires testing of hormone levels and trace elements, which may require the use of spironolactone tablets to regulate androgens or the correction of hypothyroidism through levothyroxine sodium tablets. When accompanied by scalp itching and erythema, it is necessary to rule out hair loss caused by fungal infection.

It is recommended to record the amount of hair loss daily, and seek medical attention if more than 100 hairs are lost in a single day. When washing hair, choose anti shedding shampoo containing ginger and cypress leaves, and keep the water temperature below 38 ℃. Avoid frequent perming and tight hairstyles, and use a wide toothed wooden comb to reduce pulling when combing hair. During the weight loss period, it is not advisable to lose more than 0.5 kilograms per week. You can consult a nutritionist to develop a dietary plan containing healthy fats such as salmon and nuts. If hair loss does not improve after adjusting diet, one should go to the dermatology department for folliculoscopy and blood biochemistry testing.
