Vitamins for hair growth: what you need to know

Vitamins for hair growth: what you need to know

Chapter 1: The role of vitamins in hair health: Fundamentals

Hair, often considered as an element of beauty, is actually a reflection of the general state of health. Strong, shiny and thick hair indicates a balanced diet and the lack of serious health problems. Conversely, the loss, brittleness and dullness of hair can signal the deficiency of important nutrients, in particular, vitamins.

Vitamins play a key role in various biological processes necessary to maintain the health of hair follicles, stimulate hair growth and prevent their loss. They act as catalysts of chemical reactions, participate in the synthesis of proteins (basic building material), provide antioxidant protection and improve blood circulation in the scalp.

Understanding what vitamins are most important for hair growth and how they work will help you develop an effective strategy to improve your hair.

1.1 Anatomy and physiology of hair: Brief review

Before delving into the role of vitamins, it is necessary to understand the structure of the hair and the processes occurring in the hair follicle. The hair consists of two main parts:

• Hair rod: The visible part of the hair protruding above the surface of the skin. It consists mainly of keratin protein, which gives hair strength and elasticity.
• Hair follicle: A structure located in the skin from which the hair grows. Inside the follicle there is a hair follicle containing cells that are actively divided and forming new hair.

The life cycle of the hair consists of three phases:

• Anagen (growth phase): This phase lasts from 2 to 7 years and is characterized by the active division of cells in the hair onion and hair growth.
• Katagen (Phase of Transition): This phase lasts about 2-3 weeks. Hair growth stops, and the follicle begins to contract.
• Telogen (Phase Salm): This phase lasts about 3 months. The hair stops growing and remains in the follicle until it is replaced by a new growing hair.

Violations in any of these phases can lead to hair loss or slowing down their growth. Vitamins play an important role in maintaining the normal functioning of the hair follicle and ensuring healthy hair growth at each stage of the cycle.

1.2 The effect of vitamins deficiency on hair health

The deficiency of certain vitamins can lead to various problems with hair, including:

• Hair loss: The lack of iron, biotin, vitamin D and other nutrients can disrupt the normal cycle of hair growth and lead to their loss.
• Brighten hair: The deficiency of vitamins A, C and E can weaken the structure of the hair and make them more prone brittle and damage.
• Dryness and dull hair: The lack of vitamins of group B and other nutrients can lead to dryness, dullness and loss of shine of hair.
• Slow hair growth: The deficiency of zinc, biotin and other vitamins can slow down hair growth rate.
• Seborrheic dermatitis and dandruff: The lack of certain vitamins, such as vitamin B2 (riboflavin) and vitamin B6 (pyridoxin), can contribute to the development of seborrheic dermatitis and dandruff.

The definition of a specific vitamin that your body is missing may be a difficult task, since the symptoms of deficiency are often nonspecific and can be caused by other factors. Therefore, it is recommended to consult a doctor or trichologist for diagnosis and prescribe the appropriate treatment.

Chapter 2: Key vitamins for hair growth: detailed review

Not all vitamins are equally important to the health of the hair. Some of them play a more significant role in maintaining the health of hair follicles, stimulating hair growth and preventing their loss. In this section, we will consider the most important vitamins for hair growth and their functions.
