Without pigment, new hair strands grow in lighter and take on various shades of gray, silver, and eventually white. Once a follicle stops making melanin, it won't make colored strands again.
The hair sometimes regrows white, at least in the first instance. Most people get further attacks of alopecia areata. In alopecia totalis and alopecia universalis, the likelihood of total regrowth is less.
For example, alopecia areata can increase the risk of getting vitiligo, a condition that causes the skin to lose its color.

If hair grows back, it may not have its usual colour at first and look grey or white for a while. The usual colour eventually returns after several months. Sometimes one or more bald patches develop a few weeks after the first one.
Alopecia Areata
This condition can affect adults and children, and hair loss can begin suddenly and without warning. Hair from the scalp typically falls out in small patches and is not painful. Hair in other parts of the body, including the eyebrows and eyelashes, may also fall out.
The appearance of hair whitening in both localized and diffuse forms of alopecia areata is thought to be attributable to that pigmented hairs are preferentially lost.
Once your hair follicles lose melanin, they can't produce it on their own. As melanin production slows, your hair turns gray, and then white when melanin production has completely stopped.
Marie Antoinette syndrome refers to a situation where someone's hair suddenly turns white (canities). The name of this condition comes from folklore about the French queen Marie Antoinette, whose hair supposedly turned white suddenly before her execution in 1793.
How Long does Hair Loss Last? In half of patients with alopecia areata, individual episodes of hair loss last less than one year, and hair grows back without treatment. These patients may experience recurrent episodes of hair loss that spontaneously regrow or respond quickly to treatments.
Symptoms of alopecia areata
A mild case of alopecia areata starts with one to two coin-size hairless patches. In many instances, it stops after that. Sometimes, the hair will grow back. However, there's no guarantee.
Share on Pinterest Poliosis causes white patches of hair. The white hair caused by poliosis is due to a lack of a pigment called melanin in the hair follicles. The condition is usually associated with the hair of the head. It can affect any hairy area of the body, however, including the eyebrows and eyelashes.
The patches of hair loss can grow larger. Sometimes, the patches grow larger and become one large bald spot. Other signs that you may have alopecia areata include: Gray and white hairs often remain where you have hair loss.
On the AIP elimination diet, you will avoid grains, legumes, nightshades (such as potatoes and peppers), dairy, eggs, coffee, alcohol, sugar, oil and food additives. After a few months, you can work the excluded foods back in one at a time to figure out which foods trigger an inflammatory reaction.
What is the White Bulb at End of Hair? The white bulb at the end of your hair is essentially a bundle of protein, known as keratin. The role of the white bulb is to help the hair follicle root to the scalp, which then allows the hair to grow until it is shed.
Ways to Stop Alopecia Areata from Spreading or Worsening
Avoiding unnecessary hair or scalp trauma, reducing stress and analyzing your diet are all worthwhile endeavors when attempting to prevent alopecia areata from spreading.
Although the primary cause of premature hair graying (PHG) is considered to be genetic, certain environmental factors also play a role. Trace element deficiencies such as Vitamin B12, Vitamin D3, and calcium may also be associated with PHG.
A new study shows that stress really can give you gray hair. Researchers found that the body's fight-or-flight response plays a key role in turning hair gray. Your hair color is determined by pigment-producing cells called melanocytes.
Vitamins B6 and B12 have also been proven to boost melanin production. Goddard says that vitamin B6, also known as pyridoxine, has been found to trigger the production of enzymes and chemical reactions that boost the metabolism of the hair proteins (keratin and melanin) in the hair follicles.
Premature graying hair and hair loss can be linked. However, one is not a sign that the other will occur. And, if both are happening, there may not be a link. In other words, it is important to look at other factors and determine what cause may be impacting your hair the most.
For men having white hair was a sign of distinction, hinted at nobility, and was even a sign of virility. It couldn't have been more different for women. It was a sign of their deterioration with age, and the end of their fertility.
Studies show that people with alopecia areata can have other autoimmune diseases, such as thyroid disease. However, the fact that you have alopecia areata doesn't mean you will automatically develop another autoimmune disease.
The extent of alopecia (how much hair has fallen out) varies and links to the different subtypes. Some said their hair loss involved one small patch about the size of a 1p coin which regrew after a few weeks or months. Others developed more patches which sometimes joined up into bigger bald areas over time.
Despite the claims made online and by product marketers, it's not possible to reverse white hair if the cause is genetic. Once your hair follicles lose melanin, they can't produce it on their own. As melanin production slows, your hair turns gray, and then white when melanin production has completely stopped.
