10 cause dei capelli bianchi e 12 modi per prevenirli naturalmente

Uno dei risultati più irritanti dello stile di vita moderno sono i capelli bianchi. Niente corrisponde al terrore che provi all'apparizione del tuo primo filo bianco. Sai che ce ne saranno altre da seguire e cerchi rimedi e trattamenti che potrebbero fermare l'inevitabile. Impara a sbarazzarti dei capelli bianchi.

La presenza di capelli bianchi con la vecchiaia è evidente. Ma quando li noti nei primi anni '30 e, a volte, anche 20, è assolutamente scoraggiante. Sia i capelli grigi che quelli bianchi sono il risultato della perdita di pigmento dei tuoi capelli. Quando c'è una significativa riduzione del pigmento, i capelli diventano grigi. Quando non c'è assolutamente pigmento presente, diventa bianco. La causa esatta di ciò deve ancora essere scoperta. In questo articolo, abbiamo elencato alcuni rimedi per invertire la crescita dei capelli bianchi.

Che cosa causa i capelli bianchi?

La crescita dei capelli si verifica quando le vecchie cellule vengono espulse dai follicoli piliferi a causa della produzione di nuove cellule. Si manifesta in tre fasi: crescita (anagen), cessazione (catagen) e riposo (telogen). Durante il periodo di riposo, i tuoi capelli raggiungono la loro durata di vita e cadono, e una nuova ciocca cresce al loro posto. Il colore dei capelli è prodotto dalla melanina, che è formata dai melanociti. La pigmentazione nei capelli, a differenza della pelle, non è continua. I capelli sono attivamente pigmentati nella fase anagen. La pigmentazione si riduce nella fase catagen ed è assente nella fase telogen (1).

Con l'età, la quantità di pigmento che viene iniettata in ciascuna ciocca di capelli si riduce, motivo per cui diventa grigia e infine bianca. Nella sezione sottostante sapere come fermare i capelli bianchi e i fattori che causano i capelli bianchi e come prevenire i capelli bianchi

L'inizio precoce dei capelli grigi si verifica a causa dei seguenti fattori:

1. Geni

Il dottor K. Harish Kumar, MD, DVL, afferma: "I geni sono il fattore predominante nel determinare a quale età i tuoi capelli perdono il pigmento". Per alcune persone, può accadere anche prima dei 20 anni. Per altri, le prime ciocche di bianco appaiono piuttosto tardi (1).

2. Carenza di melanina

Nella maggior parte dei casi, una carenza di melanina è la principale causa di sbiancamento dei capelli. La produzione di melanina dipende da un'alimentazione appropriata e da integratori proteici. La mancanza di questi nutrienti fa sì che la melanina scenda al di sotto dei livelli accettabili (2).

3. Ormoni

La ricerca suggerisce che uno squilibrio negli ormoni può innescare o aumentare l'ingrigimento prematuro dei capelli (1), (3). Se i capelli sono ingrigiti in eccesso e non sei sicuro di avere uno squilibrio ormonale, consulta un medico.

4. Condizioni mediche

Alcune condizioni mediche sottostanti possono innescare una perdita di pigmento nei capelli. La PGH è anche innescata da malattie autoimmuni come vitiligine, anemia perniciosa, malattie della tiroide e sindromi da invecchiamento precoce (4).

5. Carenza di vitamine e minerali

La carenza di ferro, vitamina D, acido folico, vitamina B12 e selenio può anche causare lo sbiancamento dei follicoli piliferi. Carenze di vitamina B12 e acido folico con livelli più bassi di biotina sono state riscontrate in persone con ingrigimento prematuro dei capelli (5).

6. Stress

Anche lo stress emotivo gioca un ruolo qui. Gli studi hanno dimostrato che il carico ossidativo causato dallo stress psicologico può innescare un ingrigimento prematuro dei capelli (1).

7. Prodotti chimici

A volte, l'uso di shampoo, saponi, tinture per capelli, ecc. A base chimica può causare direttamente questo problema. Tuttavia, può derivare anche da alcune infezioni allergiche.

8. Stress ossidativo

Lo stress ossidativo può causare ingrigimento precoce. È causato da una sovrapproduzione di ossidanti nel corpo, che sono anche influenzati da fattori estrinseci come raggi ultravioletti (UV), inquinamento, fattori emotivi o cause infiammatorie (2).

9. Fumo

Gli studi hanno dimostrato che il fumo è uno dei principali fattori che portano all'ingrigimento precoce dei capelli. Il fumo provoca danni alle specie reattive dell'ossigeno ai melanociti del follicolo pilifero, che porta a ingrigimento precoce (1).

10. Perossido di idrogeno

I follicoli piliferi producono piccole quantità di perossido di idrogeno, che si accumula nel tempo sui fusti dei capelli. Sbianca i capelli e li fa diventare grigi e infine bianchi (6). La rimozione di questo accumulo può aiutare i tuoi capelli a ritrovare il loro colore naturale.

Puoi sbarazzarti dei capelli bianchi?

La possibilità o meno di invertire l'ingrigimento per aiutare i capelli bianchi a diventare neri dipende in gran parte dalla causa dell'ingrigimento. Se la genetica è responsabile, non c'è molto da fare per invertire il cambiamento.

Se la causa è un problema di salute sottostante, consultare un medico per vedere cosa si può fare è la migliore linea d'azione. Una volta trattato il problema, può aiutare a ripristinare il pigmento dei capelli. Tuttavia, ciò non può essere garantito.

A volte è possibile la ripigmentazione dopo il trattamento con terapia ormonale. Un altro modo per promuovere la pigmentazione è prendere colpi o pillole di vitamina B12. Puoi anche provare i rimedi naturali menzionati di seguito e sapere come ridurre i capelli bianchi.

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.
