10 causes des cheveux blancs et 12 façons de les prévenir naturellement

Les cheveux blancs sont l'un des résultats les plus vexants du mode de vie moderne. Rien ne correspond à la peur que vous ressentez à l'apparition de votre premier brin blanc. Vous savez qu'il y en aura plus à suivre et vous recherchez des remèdes et des traitements qui pourraient arrêter l'inévitable. Sachez vous débarrasser des cheveux blancs.

L'apparition de cheveux blancs avec la vieillesse est évidente. Mais quand vous les remarquez au début de la trentaine et parfois même dans la vingtaine, c'est absolument décourageant. Les cheveux gris et blancs sont le résultat de la perte de pigment de vos cheveux. Lorsqu'il y a une réduction significative du pigment, les cheveux deviennent gris. Lorsqu'il n'y a absolument aucun pigment présent, il devient blanc. La cause exacte de ceci reste à découvrir. Dans cet article, nous avons répertorié quelques remèdes pour inverser la croissance des cheveux blancs.

Quelles sont les causes des cheveux blancs?

La croissance des cheveux se produit lorsque les vieilles cellules sont expulsées par les follicules pileux en raison de la production de nouvelles cellules. Il se produit en trois étapes: croissance (anagène), arrêt (catagène) et repos (télogène). Pendant la période de repos, vos cheveux atteignent leur durée de vie et tombent, et une nouvelle mèche pousse à sa place. La couleur des cheveux est produite par la mélanine, qui est formée par les mélanocytes. La pigmentation des cheveux, contrairement à la peau, n'est pas continue. Les cheveux sont activement pigmentés dans la phase anagène. La pigmentation diminue dans la phase catagène et est absente dans la phase télogène (1).

Avec l'âge, la quantité de pigment injectée dans chaque mèche de cheveux diminue, c'est pourquoi elle devient grise et finalement blanche. Dans la section ci-dessous, sachez comment arrêter les cheveux blancs et les facteurs provoquant les cheveux blancs et comment prévenir les cheveux blancs

L'apparition précoce des cheveux gris se produit en raison des facteurs suivants:

1. Gènes

Le Dr K. Harish Kumar, MD, DVL, déclare: «Les gènes sont le facteur prédominant pour déterminer à quel âge vos cheveux perdent leur pigment.» Pour certaines personnes, cela peut arriver avant même d'avoir 20 ans. Pour d'autres, les premiers brins blancs apparaissent assez tardivement (1).

2. Carence en mélanine

Dans la plupart des cas, une carence en mélanine est la principale cause de blanchiment des cheveux. La production de mélanine dépend d'une nutrition et de suppléments protéiques appropriés. Le manque de ces nutriments fait chuter la mélanine en dessous des niveaux acceptables (2).

3. Hormones

La recherche suggère qu'un déséquilibre des hormones peut déclencher ou augmenter le grisonnement prématuré des cheveux (1), (3). Si vous avez des cheveux grisonnants excessifs et que vous n'êtes pas sûr d'avoir un déséquilibre hormonal, veuillez consulter un médecin.

4. Conditions médicales

Certaines conditions médicales sous-jacentes peuvent déclencher une perte de pigment dans vos cheveux. La PGH est également déclenchée par des maladies auto-immunes comme le vitiligo, l'anémie pernicieuse, les maladies thyroïdiennes et les syndromes de vieillissement prématuré (4).

5. Carence en vitamines et minéraux

Une carence en fer, en vitamine D, en acide folique, en vitamine B12 et en sélénium peut également provoquer le blanchiment des follicules pileux. Des carences en vitamine B12 et en acide folique avec des niveaux inférieurs de biotine ont été constatées chez des personnes présentant un vieillissement prématuré des cheveux (5).

6. Stress

Le stress émotionnel joue également un rôle ici. Des études ont montré que la charge oxydative causée par le stress psychologique peut déclencher un vieillissement prématuré des cheveux (1).

7. Produits chimiques

Parfois, l'utilisation de shampooings, savons, teintures capillaires, etc. à base de produits chimiques peut directement causer ce problème. Cependant, il peut également résulter de certaines infections allergiques.

8. Stress oxydatif

Le stress oxydatif peut provoquer un grisonnement prématuré. Elle est due à une surproduction d'oxydants dans le corps, qui sont également affectés par des facteurs extrinsèques tels que les rayons ultraviolets (UV), la pollution, des facteurs émotionnels ou des causes inflammatoires (2).

9. Fumer

Des études ont montré que le tabagisme est l'un des principaux facteurs menant au grisonnement prématuré des cheveux. Le tabagisme cause des dommages aux mélanocytes des follicules pileux, ce qui entraîne un grisonnement prématuré (1).

10. Peroxyde d'hydrogène

Les follicules pileux produisent de petites quantités de peroxyde d'hydrogène, qui s'accumule au fil du temps sur les tiges des cheveux. Il décolore les cheveux et les fait devenir gris et finalement blancs (6). L'élimination de cette accumulation peut aider vos cheveux à retrouver leur couleur naturelle.

Pouvez-vous vous débarrasser des cheveux blancs?

La question de savoir si le grisonnement des cheveux peut être inversé pour aider les cheveux blancs à devenir noirs dépend en grande partie de la cause du grisonnement. Si la génétique est responsable, il n'y a pas grand-chose à faire pour inverser le changement.

Si la cause est un problème de santé sous-jacent, consulter un médecin pour voir ce qui peut être fait est la meilleure solution. Une fois le problème traité, cela peut aider à restaurer les pigments de vos cheveux. Cependant, cela ne peut être garanti.

La repigmentation est parfois possible après un traitement hormonal. Une autre façon de favoriser la pigmentation est de prendre des injections ou des pilules de vitamine B12. Vous pouvez également essayer les remèdes naturels mentionnés ci-dessous et savoir comment réduire les cheveux blancs.

In addition to following the remedies listed above, you can also follow these tips to reduce gray hair.

Tips

1. Increase Intake Of Vitamin B12

Your hair could be turning white due to a deficiency of vitamin B12 (5). If this is the case, reversing the graying process could be as simple as consuming sufficient amounts of the vitamin.

Vitamin B12 deficiency causes pernicious anemia, and your hair losing its pigment is a symptom of the condition. This condition can be reversed by maintaining a balanced diet that is giving you the right amounts of the vitamin.

2. Increase Intake of Vitamin B5

Vitamin B5 is known to help prevent the early onset of graying hair and restore its natural color (20). It also aids hair growth, gives hair proper moisture, and has anti-inflammatory properties.

Consume foods rich in vitamin B5 like mushrooms, beef liver, eggs, whole grains, broccoli, sunflower seeds, etc. (21).

3. Keep The Thyroid Levels In Check

Your thyroid gland has an impact on all the vital functions of your body. An underactive thyroid, or hypothyroidism, can result in premature white hair (3). It is necessary to monitor your thyroid levels to be aware if it is causing the loss of pigment in your hair.

Hypothyroidism is a serious chronic condition and might require hormone supplementation. Certain foods can interfere with the working of your thyroid gland. To keep your thyroid levels in check, keep tabs on your diet.

4. Quit Smoking

Your lifestyle has a huge influence on the health and color of your hair. Smoking has adverse effects on your body and could be contributing to white hair (1). A study determined that smokers have a higher chance of their hair losing pigment than non-smokers (22).

5. Load Up On Antioxidants

Your diet may help prevent the occurrence of white hair. Make sure that you consume enough antioxidant-rich foods.

6. Protect Your Hair From UV Rays

One of the extrinsic factors of oxidative stress is UV rays, which lead to premature graying of hair. Make sure you protect your hair when going out in the sun with a scarf or hat. There are a number of heat protection products that protect hair follicles from the harmful sun rays.

7. Foods To Eat To Reduce White Hair

Also, consume antioxidant-rich foods such as berries, grapes, green leafy vegetables, and green tea.

Here’s a list of foods that can help aid hair growth and delay premature graying of hair (20):

• Berries – They are rich in vitamin C.
• Meat liver – Combats anemia and iron deficiencies.
• Carrots – Rich in vitamin A.
• Curry leaves – Rich in the B vitamins and minerals such as selenium, iodine, zinc, and iron.
• Spinach – Helps in the production of melanin.
• Eggs – Rich in vitamin B12.
• Beans – Rich source of protein.
• Sunflower seeds – Rich in antioxidants and minerals.
• Walnuts – Rich source of copper, which helps in melanin production.

Can White Hair Turn Black Again?

A 2016 mice study targeted molecular pathways that control hair pigmentation to restore color. The mice exhibited growth of melanocytes that form melanin in the skin and hair. The discovery suggested that developing a drug or other therapy to target these pathways may help bring back some color to gray tresses (23).

With the right diagnosis and treatments, graying can be reversed, and white hair can turn black. But if the problem is genetic or age-related, it is unlikely to reverse the process. It is possible, however, to slow it down with a balanced diet and a good hair care regimen.

It is natural for your hair to lose its pigmentation, and it’s up to you if you want to color it or display it in all of its glory. The consistent use of these remedies can help slow and reverse hair fall and graying of hair. They may work gradually, but with patience, you will see visible results.
