I. What is biotin?

Biotin is a water-soluble vitamin belonging to the B vitamin family. It plays an important role in the metabolism of proteins, lipids and carbohydrates, thus contributing to homeostasis (in other words balance) of the body.

And what is the link between biotin and hair?

Its role is particularly important for the hair since biotin is involved in the production of keratin . You know, this protein that mainly makes up our hair . It thus helps maintain strong, resistant and vibrant hair. It is, in a way, the main element of hair.

So if we participate in the production of this precious protein, we ensure healthy hair. And that is exactly the role of biotin.

II. The benefits of biotin for hair

Biotin is the hair supplement that ticks all the boxes: Growth? Check! ✓ Reinforcement? Check! ✓ Thickening? Check too! ✓

1) Hair Growth

Biotin stimulates cell division in hair follicles (tiny structures located under the skin from which hair grows), thereby promoting hair growth . In addition, it prolongs the growth phase of the hair cycle, which reduces hair loss.

2) Strengthening and thickening

Through its role in the production of keratin, biotin helps strengthen hair structure, making it less prone to breakage. Additionally, it can help increase hair diameter, perfect for making hair look thicker and fuller.

3) Improved scalp quality

Adequate consumption of biotin can also promote a healthy scalp by reducing irritation and inflammation. And a healthy scalp is essential for strong, vigorous hair.

They allow the body to fully benefit from the benefits of biotin . By regularly taking biotin-based supplements, you promote the overall health of your hair by providing it with the necessary quantity of this vitamin.

☝🏼️ Good to know: Choose a supplement based on biotin coupled with other ingredients beneficial for the hair . Look for products that also contain other vitamins and minerals important for hair health, such as selenium, zinc, and collagen. These synergies also make it possible to reinforce the effectiveness of your treatment.

IV. How much biotin per day to have beautiful hair?

The recommended daily biotin intake is 50µg for adults .

In order to obtain the expected results on the hair (but also the nails and the skin), it is possible to consume a higher dose.

Biotin is a water-soluble vitamin, meaning it is easily eliminated from the body via urine if consumed in excess. As a result, overdoses are very rare.

⚠️ Be careful, don't make us say what we haven't said: when you start any supplementation, it is important to respect the dosages recommended by the manufacturer.

Focus on foods rich in biotin:

Biotin is found naturally in certain foods, making it easy for you to incorporate it into your daily life.

Foods rich in biotin include egg yolks, organ meats (liver and kidneys), nuts, seeds, banana, avocado, brewer's yeast (well, that's why!) and cauliflower. Legumes, mushrooms and salmon are also good sources of biotin.

Speaking of foods that are good for hair, zinc and selenium are not left out!
They play an important role in hair beauty by promoting growth and strengthening hair. So don't forget them when preparing your meals because a balanced diet always remains the key to healthy hair!

And if you are wondering where to find zinc in food, well we have already written the answer for you: Foods rich in zinc !

☝🏼️Did you know? The intestinal flora can synthesize biotin from certain elements of our diet (these bacteria are too strong!). However, the quantity produced is often not sufficient to cover our needs. This is why biotin must be provided through diet or supplementation.

V. Side effects of biotin and how to reduce them

In rare cases, some people may experience side effects such as digestive discomfort, skin rashes or itching.

If you have followed the dosages and instructions for use but nasty side effects appear, don't worry: try reducing the dose of biotin or taking it with a meal to minimize the effects on the digestive system. .

If digestive discomfort persists or breakouts appear, stop your supplementation and instead turn to other supplements to pamper your hair. Why not try moringa, for example? This super plant also offers excellent benefits for your hair .

VI. How to Use Biotin for Optimal Results

The best way to benefit from biotin for visible results is to choose the option that is easiest and least restrictive for you.

Focusing on shampoos enriched with biotin, for example, allows you to benefit from the benefits of biotin without even thinking about it: with each shampoo, presto, a dose of biotin!

VII. Biotin assimilation inhibitors and interferences

Assimilation inhibitors

Certain elements can play spoilsport and prevent biotin from working fully. How ? By interfering with the absorption of biotin, thereby reducing its effectiveness.

They are called “Assimilation Inhibitors”. Among them, we find:

  • - Alcohol 🍷: excessive or regular consumption of alcohol can lead to a reduction in the absorption of biotin. If you want to take care of your hair (and not only that) you will therefore have to reduce alcohol consumption.

  • - Raw eggs 🍳 (for athletes who love raw eggs before exercise, we're talking to you!) or barely cooked. Egg whites contain a protein called avidin, which can bind to biotin and prevent it from being absorbed by the body. So be careful about cooking your egg if you take your biotin supplement at the same time.

    💊 Also warn about taking antibiotics, which, by modifying the intestinal flora, can reduce the assimilation of biotin.

Biotin Interferences

There is a risk of interference between biotin supplementation and thyroid hormone assays , potentially distorting results and leading to a false diagnosis of hypothyroidism or hyperthyroidism. It is therefore crucial to inform your doctor as well as the analysis laboratory that you are taking biotin before carrying out these tests.

VIII. Time to observe the first results of biotin on hair

It should be kept in mind that results may vary from person to person. In general, the first positive effects of biotin on hair can be observed after a few weeks of regular use.

However, patience and regularity are essential! As with nails that we would like to see grow as quickly as possible , hair growth takes time, and even with a good boost from biotin , you have to know how to stay calm and persevere.
The effects of biotin take a little time, but it's so worth it!

While waiting for the long-awaited results of biotin on your hair, continue to take care of your hair by using appropriate hair care products and adopting a healthy lifestyle. We can't promise you Rapunzel's hair, but we assure you that you're on the right track. 👑
