Gives a general picture of the body's condition. Helps to identify anemia, inflammatory processes and latent deficiencies that can provoke hair loss.

Important for cell division, keratin synthesis and overall hair growth. Plays a key role in tissue regeneration and the functioning of the immune system. Zinc deficiency is often accompanied by dullness and hair loss.
Normal range: 11–24 µmol/l
Reasons for increased values: taking supplements, dehydration
Reasons for decreased values: dietary deficiency, chronic inflammation, absorption disorder
Iron is necessary for the synthesis of hemoglobin and saturation of tissues with oxygen. Deficiency of this element is one of the common causes of diffuse hair loss.
Normal range:
Women: 8.9–30.4 µmol/l
Men: 11.6–31.3 µmol/l
Reasons for increased values: hemochromatosis, taking iron supplements
Reasons for decreased values: iron deficiency, blood loss, chronic diseases
An indicator of iron reserves in the body. With a decrease in ferritin, hair begins to fall out even with a normal level of iron in the blood serum.
Normal range:
Women: 10–120 µg/ml
Men: 20–250 µg/ml
Reasons for increased values: inflammation, infections, iron overload
Reasons for decreased values: iron deficiency, chronic blood loss, vegetarianism
Participates in cell division, hematopoiesis and amino acid synthesis. Folate deficiency affects the nutrition of hair follicles and can slow hair growth.
Normal range: >3 ng/ml
Reasons for increased values: taking supplements
Reasons for decreased values: deficiency in the diet, alcoholism, diseases Gastrointestinal tract
Regulates thyroid function and thyroid hormone levels. They affect metabolism, hair growth, thermoregulation and energy levels.
Normal range: 0.4–4.0 mIU/l
Reasons for increased values: hypothyroidism, thyroiditis
Reasons for decreased values: thyrotoxicosis, pituitary insufficiency
In men − the main sex hormone, in women − in small quantities it participates in the regulation of the sebaceous glands and follicles. If in excess, it can cause androgenetic alopecia.
Normal range:
Women: 0.52–1.72 nmol/l
Men: 8.64–29 nmol/l
Reasons for increased values: PCOS, tumors, adrenal hyperplasia
Reasons for decreased values: hypogonadism, age, antiandrogen use
Participates in cell division, hematopoiesis and tissue nutrition. A deficiency leads to anemia and deterioration of the skin and hair.
Normal range: 197–771 pg/ml
Reasons for increased values: vitamins intake, liver disease
Reasons for decreased values: gastritis, malabsorption, vegetarianism
Affects immunity, cell division and skin health. Reduced levels of vitamin D can lead to chronic, seasonal or diffuse hair loss.
Normal range: 30–100 ng/ml
Reasons for increased values: taking high doses, sarcoidosis
Reasons for decreased values: sun deficiency, malabsorption, obesity
