Safe dietary supplements for hair growth: We study contraindications

Chapter 1: Fundamentals of hair growth and causes of loss

1. Hair growth cycle: fundamental understanding
Hair passes through a cyclic growth process, including three main phases: anagen (growth phase), catagen (transition phase) and bodyogen (rest phase). The duration of each phase varies and depends on many factors, including genetics, age, general health and hormonal balance.
- Anaagen: This phase is the longest and lasts from two to seven years. During the anagen, the hair follicle actively produces new cells, leading to hair growth. About 80-90% of the hair on the head is in this phase at any time.
- Catagen: This phase is a short transition period lasting about two to three weeks. During the catagen, hair growth slows down, and the hair follicle begins to contract.
- Telogen: This phase is a phase of rest and lasts about three months. During the heterogene, hair growth ceases, and it remains in the follicle until it is pushed out by a new growing hair. About 10-20% of the hair on the head is in this phase at any time.
Violation of a normal hair growth cycle can lead to hair loss. For example, a reduction in the anagen phase or an increase in the heterogene phase can lead to the fact that more hair will be in the rest phase and, therefore, falling out.
1. The main causes of hair loss: complex look
Hair loss can be caused by many factors, and often is the result of a combination of several reasons. It is important to determine the main cause of hair loss in order to choose the most effective treatment method.
- Genetic predisposition: Androgenetic alopecia, also known as baldness by male or female type, is the most common cause of hair loss. It is due to a genetic predisposition and is associated with the effects of dihydrotestosterone (DGT) on hair follicles.
- Hormonal changes: Hormonal changes associated with pregnancy, birth, menopause or thyroid diseases can lead to hair loss.
- Stress: Physical or emotional stress can lead to heterogene alopecia, in which a large amount of hair passes into the heterogene phase and falls in a few months.
- Inal meals: The deficiency of vitamins and minerals, such as iron, zinc, biotin and vitamin D, can adversely affect the health of the hair and lead to their loss.
- Medical conditions and medicines: Some medical conditions, such as autoimmune diseases, scalp infections and some drugs, such as chemotherapeutic drugs, can cause hair loss.
- Hair damage: Excessive use of a hair dryer, ironing, chemical curling or hair dyeing can damage hair and lead to its brittleness and loss.
1. Diagnosis of the causes of hair loss: the key to successful treatment
Proper diagnosis is the first and most important step in the treatment of hair loss. It is important to consult a trichologist or dermatologist to establish the cause of hair loss and develop an individual treatment plan.
- Anamnesis: The doctor will collect information about your health, lifestyle, family history and medicines that you take.
- Physical examination: The doctor will examine your scalp and hair to evaluate the degree and nature of hair loss.
- Trichoscopy: This is a non -invasive diagnostic method in which the doctor uses a dermatoscope for a detailed study of the condition of the hair and scalp.
- Blood tests: Blood tests can be prescribed to detect a deficiency of vitamins and minerals, hormonal disorders or other medical conditions that can cause hair loss.
- Scalp biopsy: In rare cases, a scalp biopsy may be required to establish an accurate diagnosis.
