Effective dietary supplements for hair growth: proven effectiveness

Section 1: Understanding the problem of hair loss and the need for an integrated approach

1. Epidemiology and prevalence of hair loss:

   • Hair loss is a global problem that affects millions of men and women of all ages. The assessment of prevalence varies depending on the age, gender, ethnicity and the definitions used.
   • Androgenetic alopecia (yeah), or baldness by male type/female type, is the most common form of hair loss, which accounts for more than 95% of cases. In men, yeah usually begins with the thinning of hair in the temple and crown, gradually moving on to the formation of a characteristic M-shaped hair growth line. In women, yeah usually manifests itself in the form of diffuse thinning of hair throughout the head, preserving the hair growth line.
   • According to estimates, by the age of 50, approximately 50% of men experience signs of aha. In women, the prevalence of aha increases with age, affecting a significant part of women after menopause.
   • Other forms of hair loss include heaponal alopecia (temporary hair loss, often caused by stress, pregnancy or disease), nesting alopecia (an autoimmune disease causing focal hair loss), traction alopecia (caused by tight hairstyles) and cicatricial alopecia (caused by inflammation or rumper).
   • The prevalence of these various forms of hair loss is significantly different, but in aggregate they have a significant impact on the quality of life and self -esteem of the victims.

2. Hair health factors:

   • Hair health is a complex process, which is affected by numerous factors, including genetics, hormones, nutrition, stress and hair care.
   • A genetic predisposition plays an important role in the development of aha. Heredity from both parents can affect the sensitivity of hair follicles to dihydrotestosterone (DGT), a hormone responsible for the miniaturization of hair follicles and hair loss at aha.
   • Hormonal changes, such as those that occur during puberty, pregnancy, menopause and thyroid diseases, can also affect the growth and loss of hair. The imbalance of hormones, such as estrogen, progesterone and thyroid hormones, can disrupt the normal cycle of hair growth.
   • Nutrition plays a crucial role in hair health. Hair for growth and development needs certain vitamins, minerals and amino acids. The deficiency of nutrients such as iron, zinc, biotin, vitamin D and protein can lead to hair loss, brittleness and slow hair growth.
   • Chronic stress can have a significant effect on hair health. Stress can lead to heterogene alopecia, the temporal loss of hair, which occurs when more hair follicles, than usual, pass into the rest phase (bodyogen). Stress can also aggravate other states associated with hair loss, such as aha and nesting alopecia.
   • Aggressive methods of hair care, such as frequent use of thermal tools, chemical treatment and tight hairstyles, can damage the hair rod and lead to brittleness and hair loss.
   • Some drugs and diseases can also cause hair loss. It is important to discuss with the doctor any drugs that you take, and any basic diseases that can contribute to hair loss.

3. Diagnosis and treatment of hair loss: the need for an integrated approach:

   • The exact diagnosis is crucial for determining the main cause of hair loss and the development of the corresponding treatment plan. The doctor can conduct a physical examination, collect the medical history and conduct blood tests to exclude any basic diseases or a deficiency of nutrients.
   • In some cases, a scalp biopsy may be required to confirm the diagnosis. The scalp biopsy includes a small scalp sample for a microscopic examination.
   • Options for the treatment of hair loss vary depending on the main cause. Medicines for the prescription, such as minoxidil and finsteride, are approved for the treatment of aha. Minoxidil is a local treatment that stimulates hair growth, and finsterida is an oral medicine that blocks the production of DGT.
   • Other hair loss treatment options include low -intensity laser therapy (LLLT), corticosteroid injections, immunotherapy and hair transplant.
   • Addresses for hair growth can be a useful addition to a comprehensive plan for the treatment of hair loss. However, it is important to note that additives should not be considered as a replacement for traditional treatment.
   • A comprehensive approach to the treatment of hair loss includes eliminating any basic diseases or a deficiency of nutrients, conducting a healthy lifestyle, minimizing stress and using gentle methods of hair care. It is important to consult a doctor to determine the best treatment plan for your individual needs.
