Vitamins for hair growth: what do research say
The issue of accelerating hair growth worries many, and it is not surprising that vitamins are positioned as one of the key solutions. However, a lot of myths and unconfirmed statements are hovering around this topic. To understand the effectiveness of vitamins for hair growth, you need to contact scientific research and carefully analyze the available data. This article is a comprehensive overview of vitamins and trace elements often associated with hair growth, based on the results of scientific research. We will consider their role in the health of the hair, symptoms of deficiency, as well as the effectiveness of additives for people with and without deficiency.
I. Fundamentals of hair health and factors affecting hair growth
Before delving into specific vitamins, it is important to understand the basics of hair health and factors affecting their growth.
-
Hair structure: The hair consists of three main parts: cuticles (outer layer), bark (the middle layer containing keratin) and core (not always present). A healthy cuticle protects the hair from damage and provides shine. The bark is responsible for the strength and elasticity of the hair.
-
Hair growth cycle: Hair passes through three phases: anagen (growth phase), catagen (transitional phase) and bodyogen (rest phase). In the anagen phase, which lasts from 2 to 7 years, the hair is actively growing. In the catagen phase, lasting about 2-3 weeks, hair growth stops. In the heterogene phase, lasting about 3 months, the hair is at rest, after which it falls out, and new hair begins to grow in their place.
-
Hair growth factors: Many factors affect the hair growth cycle and the general health of hair, including:
- Genetics: A genetic predisposition plays an important role in determining the density, thickness and speed of hair growth.
- Age: With age, the hair growth rate slows down, and the hair becomes thinner and weaker.
- Hormonal balance: Hormones, such as testosterone, estrogen and thyroid hormones, play an important role in the regulation of hair growth. The imbalance of these hormones can lead to hair loss.
- Nutrition: The lack of necessary nutrients, such as vitamins, minerals and protein, can adversely affect the health of the hair.
- Stress: Chronic stress can lead to hair loss.
- Diseases: Some diseases, such as autoimmune diseases and thyroid diseases, can cause hair loss.
- Medicines: Some drugs, such as chemotherapy and antidepressants, may have a side effect in the form of hair loss.
- Hair care: Aggressive styling methods, such as frequent use of a hair dryer, ironing and chemical curling, can damage the hair and slow down their growth.
II. Vitamins and their role in hair health: scientific data
Consider vitamins that are most often associated with hair growth, and study what scientific research is said about them.
