10 causas de cabelos brancos e 12 maneiras de evitá-los naturalmente

Um dos resultados mais irritantes do estilo de vida moderno é o cabelo branco. Nada se compara ao pavor que você sente ao aparecer seu primeiro fio branco. Você sabe que haverá mais a seguir e procura remédios e tratamentos que possam impedir o inevitável. Saiba como se livrar dos cabelos brancos.

A ocorrência de cabelos brancos com a idade é óbvia. Mas quando você os nota por volta dos 30 anos e às vezes até dos 20 anos, é absolutamente desanimador. Os cabelos grisalhos e brancos são o resultado da perda de pigmento do seu cabelo. Quando há redução significativa do pigmento, o cabelo fica grisalho. Quando não há absolutamente nenhum pigmento presente, ele fica branco. A causa exata disso ainda não foi descoberta. Neste artigo, listamos alguns remédios para reverter o crescimento dos cabelos brancos.

O que causa cabelos brancos?

O crescimento do cabelo ocorre quando as células velhas são empurradas para fora pelos folículos capilares devido à produção de novas células. Ocorre em três estágios - crescimento (anágeno), cessação (catágeno) e repouso (telógeno). Durante o período de descanso, seu cabelo atinge sua vida útil e cai, e uma nova mecha cresce em seu lugar. A cor do cabelo é produzida pela melanina, que é formada pelos melanócitos. A pigmentação do cabelo, ao contrário da pele, não é contínua. O cabelo é pigmentado ativamente na fase anágena. A pigmentação diminui na fase catágena e está ausente na fase telógena (1).

Com a idade, a quantidade de pigmento injetado em cada fio de cabelo diminui, e é por isso que ele fica cinza e eventualmente branco. Na seção abaixo, saiba como parar de cabelos brancos e os fatores que causam cabelos brancos e como prevenir os cabelos brancos

O aparecimento precoce de cabelos grisalhos ocorre devido aos seguintes fatores:

1. Genes

Dr. K. Harish Kumar, MD, DVL, diz: "Os genes são o fator predominante na determinação da idade em que seu cabelo perde pigmento." Para algumas pessoas, pode acontecer antes mesmo de completarem 20 anos. Para outras, os primeiros fios brancos aparecem um pouco tarde (1).

2. Deficiência de melanina

Na maioria dos casos, a deficiência de melanina é a principal causa do clareamento do cabelo. A produção de melanina depende de nutrição adequada e suplementos protéicos. A falta desses nutrientes faz com que a melanina caia abaixo dos níveis aceitáveis ​​(2).

3. Hormônios

A pesquisa sugere que um desequilíbrio nos hormônios pode desencadear ou aumentar o envelhecimento prematuro do cabelo (1), (3). Se você tem cabelos grisalhos em excesso e não tem certeza se tem um desequilíbrio hormonal, consulte um médico.

4. Condições médicas

Certas condições médicas subjacentes podem desencadear uma perda de pigmento no cabelo. A PGH também é desencadeada por doenças autoimunes, como vitiligo, anemia perniciosa, doenças da tireoide e síndromes do envelhecimento prematuro (4).

5. Deficiência de vitaminas e minerais

A deficiência de ferro, vitamina D, folato, vitamina B12 e selênio também pode causar o clareamento dos folículos capilares. Deficiências de vitamina B12 e ácido fólico com níveis mais baixos de biotina foram encontradas em pessoas com cabelos grisalhos prematuros (5).

6. Estresse

O estresse emocional também desempenha um papel aqui. Estudos têm demonstrado que a carga oxidativa causada pelo estresse psicológico pode desencadear o envelhecimento prematuro dos cabelos (1).

7. Produtos Químicos

Às vezes, o uso de xampus, sabonetes, tinturas de cabelo de base química etc. pode causar diretamente esse problema. No entanto, também pode resultar de algumas infecções alérgicas.

8. Estresse Oxidativo

O estresse oxidativo pode causar envelhecimento prematuro. É causada por uma superprodução de oxidantes no corpo, que também são afetados por fatores extrínsecos como raios ultravioleta (UV), poluição, fatores emocionais ou causas inflamatórias (2).

9. Fumar

Estudos têm demonstrado que fumar é um dos principais fatores que levam ao envelhecimento prematuro dos cabelos. Fumar causa danos de espécies reativas de oxigênio aos melanócitos do folículo piloso, o que leva ao envelhecimento prematuro (1).

10. Peróxido de hidrogênio

Os folículos capilares produzem pequenas quantidades de peróxido de hidrogênio, que se acumula nas hastes do cabelo com o tempo. Ele branqueia o cabelo e o torna grisalho e, eventualmente, branco (6). A remoção desse acúmulo pode ajudar seu cabelo a recuperar sua cor natural.

Você pode se livrar do cabelo branco?

Se o cabelo grisalho pode ou não ser revertido para ajudar o cabelo branco a ficar preto depende muito da causa do envelhecimento. Se a genética for a responsável, não há muito o que fazer para reverter a mudança.

Se a causa for um problema de saúde subjacente, consultar um médico para ver o que pode ser feito é o melhor curso de ação. Assim que o problema for tratado, isso pode ajudar a restaurar a pigmentação do cabelo. No entanto, isso não pode ser garantido.

A repigmentação às vezes é possível após o tratamento com terapia hormonal. Outra forma de promover a pigmentação é tomando injeções ou comprimidos de vitamina B12. Você também pode experimentar os remédios naturais mencionados abaixo e saber como reduzir os cabelos brancos.

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.
