Understanding Hair Growth
Hair growth cycle
The health and beauty of hair are at the heart of our Presidents' concerns. However, to effectively care for your hair, it is essential to understand the hair life cycle, a natural process composed of different phases.
- The Anagen (Growth) Phase : The anagen phase is the first stage of the hair cycle. During this period, which can last anywhere from two to six years, hair is actively growing. Nutrients and care play a crucial role in hair health and length during this phase.
- The Catagen Phase (Transition) : The catagen phase marks a transition period that lasts approximately two to three weeks. During this time, hair growth slows and the follicle shrinks, preparing the hair to enter the resting phase.
- Telogen (Resting) Phase : The telogen phase is the last stage of the cycle and can last up to three months. During this phase, hair does not grow but remains attached to the follicle. It is at the end of this period that natural hair loss occurs, making way for new hair.

Factors Affecting Hair Health
There are several factors that can influence the hair cycle, including nutrition, stress and hair care choices. A diet rich in vitamins, minerals and proteins is essential to support hair growth. Stress can cause hair to enter the telogen phase prematurely, leading to more hair loss. Excessive use of chemicals or heat treatments can damage hair and disrupt its natural cycle. Here are our tips:
- Balanced diet : Include foods rich in iron, zinc, vitamin D and omega-3 in your diet to promote healthy growth.
- Reduce stress : Practice relaxing activities like yoga or meditation to minimize the impact of stress on your hair.
- Proper care : Use gentle shampoos, conditioners and hair masks to nourish and protect your hair during all phases of its cycle.

Food supplements and hair growth
The quest for thick, healthy hair is common to many of us. While genetic factors play a major role, proper nutrition and hair care are essential to promote healthy hair and growth. Among the effective strategies to stimulate hair growth, dietary supplements occupy a prominent place.
Hair, like any other part of the body, requires a regular supply of specific nutrients to grow healthily. However, modern diets do not always provide the necessary amounts of these essential nutrients. This is where nutritional supplements come in, filling in the nutritional gaps and providing hair follicles with the elements they need to produce strong, healthy hair.

With a wide range of supplements available on the market, choosing the right product can be tricky. It is crucial to look for high-quality supplements that are formulated specifically for hair health and contain effective concentrations of the nutrients mentioned above. Additionally, it is recommended to consult a healthcare professional before beginning any supplement regimen, especially if you have pre-existing medical conditions.
Types of dietary supplements
Essential vitamins and minerals:
- Vitamin A : Essential for all cells to grow, vitamin A also helps the glands in the skin produce sebum. This moisturizes the scalp and helps keep hair healthy.
- B vitamins , especially Biotin: Known to promote hair growth and improve its texture, B vitamins, and particularly biotin, are often prescribed in cases of hair loss. Vitamin B6 plays a crucial role in hair growth, as it actively participates in the synthesis of keratin, an essential protein that makes up the hair fiber. By improving the metabolic activity of scalp cells, it promotes a healthy environment conducive to hair growth. Its presence in food supplements helps strengthen hair from the inside, making it more resistant and vigorous.

- Vitamin C : A powerful antioxidant that helps protect against oxidative stress caused by free radicals. It also plays a key role in the production of collagen, an important protein for healthy hair.
- Vitamin D : Its deficiency has been linked to alopecia, the autoimmune disease that causes hair loss. Vitamin D can help create new follicles – the small pores in the scalp where new hair can grow.
- Vitamin E : Like vitamin C, vitamin E is an antioxidant that can prevent oxidative stress.
- Zinc : This mineral plays a crucial role in tissue repair and hair growth. A zinc deficiency can lead to hair loss.

- Iron : Iron helps red blood cells carry oxygen to cells, including hair follicles, which is essential for hair growth.
- Omega-3 : These essential fatty acids have anti-inflammatory properties that can help open follicles and promote hair growth.

- Brewer's yeast: Brewer's yeast, the key to hair growth supplements, is valued for its richness in vitamin B. Enriching the hair fiber, brewer's yeast stimulates cell regeneration and keratin production. Finally, brewer's yeast provides targeted nutrition to the scalp, promoting rapid and healthy hair growth.
- Methionine: An essential amino acid, it plays a crucial role in the production of keratin, thus strengthening the structure and resilience of hair.
Although we can get many of these vitamins and minerals through our diet, modern lifestyles, stress and an unbalanced diet can lead to deficiencies. Hair growth supplements help fill these gaps, providing targeted nutritional support to stimulate hair growth and health. How to choose the right supplements?
-
Look for products that contain a combination of these vitamins and minerals for optimal effectiveness.
-
Choose high-quality supplements, ideally recommended by health professionals.
-
Always consult a healthcare professional before starting any new dietary supplement, especially if you have any pre-existing medical conditions.
Plant and herbal extracts
- Nettle : Rich in silica and sulfur, nettle helps make hair shinier and stronger. Its high content of essential minerals can also help reduce hair loss.

- Saw Palmetto : Often used to counteract hair loss linked to DHT (dihydrotestosterone), Saw Palmetto is known for its blocking action on enzymes that promote hair loss.
- Bamboo : Bamboo, rich in silica, helps improve hair elasticity and strength, while stimulating hair growth.

- Castor Oil : Although technically not an herb, castor oil is extracted from the seeds of the castor plant and is widely praised for its hair growth-promoting properties.
- Aloe Vera : Known for its soothing and moisturizing properties, aloe vera promotes a healthy scalp and stimulates hair growth from the roots.

Amino acids and proteins
Hair is primarily composed of keratin, a structural protein that gives it strength and elasticity. Keratin itself is made up of different types of amino acids, the presence of which in sufficient quantities is crucial for maintaining the structure and health of hair. Amino acids such as cysteine, lysine, arginine and methionine play a specific role in hair protection, repair and growth.
A closer look at the amino acids and proteins that promote hair growth:
- Cysteine : This amino acid is a major component of keratin. Cysteine promotes hair strength and can protect the hair follicle from damage.
- Lysine : Lysine is involved in the absorption of iron, a mineral essential for hair growth. A deficiency in lysine can therefore slow hair growth.
- Arginine : Arginine helps improve blood circulation to the scalp, which stimulates hair follicles and encourages hair growth.
- Methionine : A powerful antioxidant that can slow hair graying and hair loss by stimulating collagen production

Choice and use of food supplements
How to choose the right supplement
Hair growth supplements come in a variety of forms, including capsules, tablets, liquids, and powders. Your choice may depend on your personal preference and how easy it is to incorporate the supplement into your daily routine.
Safety should be your top priority when choosing a dietary supplement. Look for products that are approved by recognized health authorities and manufactured by trusted brands that practice transparency regarding their ingredients and sources.
Before adding any new supplement to your routine, it is advisable to consult a healthcare professional. This is especially important if you have any pre-existing medical conditions or are taking other medications.

Directions for use and dosage
Adding supplements to your hair care routine can be a great way to encourage growth and improve the health of your hair. However, to ensure not only their effectiveness but also your safety, it is crucial to follow the instructions carefully and stick to the recommended dosage. Here are some essential guidelines to help you.
Each hair growth supplement comes with specific dosage recommendations provided by the manufacturer. These recommendations are based on the amount of active ingredients in the product and their optimal concentration to achieve the best results without risking overdosing.
- Read the Label Carefully: Before you start using any supplement, be sure to read the label and the instructions provided. This will give you valuable information about the recommended daily dose and how to consume the product.

-
Follow the recommended dose: Do not exceed the suggested dose in the hope of speeding up results. Overdosing on certain nutrients, even those that are beneficial for hair growth, can have adverse effects.
-
Daily Consumption: For best results, dietary supplements should generally be taken regularly every day. Following a consistent schedule helps your body assimilate nutrients optimally.

-
Timing : Some supplements may be better absorbed when taken with food, while others may be recommended on an empty stomach. Check specific instructions regarding timing to maximize the effectiveness of the supplement.
-
Patience and Perseverance: Hair growth is a gradual process. It may take several weeks or even months to see noticeable changes. It is important to remain patient and continue taking the supplement regularly to properly assess its effectiveness.

- Periodic evaluation: After using the supplement for the recommended duration, evaluate the results. If you are satisfied with the progress, you can choose to continue use. Otherwise, you can consult a healthcare professional to adjust your approach.
