One dog owner can attest to this, as their pet dog Buster, a four-year-old black dog from Oklahoma, ended up turning completely white because of vitiligo. People of all races and skin colors can get vitiligo, and the disease occurs about equally in people of all races. While having a close blood relative with vitiligo increases your risk of developing it, not everyone who has vitiligo in their family develops this disease. Some people only get a few small, white patches, but others get bigger white patches that join up across large areas of their skin. It can also sometimes develop where there are hair roots, such as on your scalp. The lack of melanin in your skin can turn the hair in the affected area white or grey.

You'll need to be in a dark room and the lamp will be held 10 to 13cm away from your skin. A GP will be able to diagnose vitiligo after examining the affected areas of skin. They're sometimes red and inflamed, or there's brownish discolouration (hyperpigmentation).
Why You Shouldn’t Skip Your Dermatology Appointment During COVID-19
When a person has vitiligo, cells that make pigment are damaged. Because these cells give the skin its color, spots and patches of lighter skin appear. Vitiligo can appear anywhere on a person’s skin, including the genitals. Vitiligo can cause hair to lose color, but it doesn't cause hair loss.
Risk factors
Vitiligo affects people of all skin types, but it may be more noticeable in people with brown or Black skin. Some people embrace vitiligo hair, while others prefer to hide it if they can. Vitiligo is not harmful to your physical health, but it can impact your self-esteem. Talk to your healthcare provider about treatment options for vitiligo or ask about a referral to a mental health provider if this condition is negatively affecting your self-esteem.
Segmental Vitiligo
However, it is important to note that not everyone with a genetic predisposition to vitiligo will develop the condition. Environmental factors and other triggers may also be necessary for the onset of vitiligo. While vitiligo is not a serious disease, people differ in how they view it when it affects them.
Heredity plays a part, and there may be an event that triggers the start of vitiligo, such as a sunburn or stress. It affects both genders, and people of all ethnic origins equally, though it is more noticeable on darker skin. Vitiligo is a skin disease that leads to the development of smooth white areas where the skin loses its color.
Although vitiligo can develop in anyone at any age, macules or patches usually become apparent before age 30. Hair loss is fairly common and may result from hormones, medical conditions, extreme stress, treatments such as chemotherapy, and more. Hair loss can range from thinning to total loss of hair, can be temporary or permanent, and can affect all ages and genders. There is no controlled data showing the efficacy of this product as an addition to specific treatments for hair loss conditions. A 2023 study found that participants given this supplement had a better response to hair treatments than those who received the treatments alone, but the study had several limitations.
Where skin spots appear, how widespread the condition becomes, and how much it will progress vary from person to person. When medication is used along with self-care, many patients keep the color that treatment added to their skin. Surgery usually isn’t recommended for people who have active vitiligo, which means that over the last 12 months new spots have developed or existing spots have grown. After giving you the diagnosis, your dermatologist will also ask whether you want to treat the vitiligo.

Vitiligo is believed to be an autoimmune condition, where the body’s immune system attacks and destroys the melanocytes – the cells that produce pigment in the skin. This leads to the depigmentation of the skin and the development of white patches. Vitiligo is a chronic skin disorder that affects an estimated 0.5% to 1% of the world’s population. It occurs when the cells that produce melanin, the pigment that gives color to the skin, die or stop functioning. As a result, the affected area of the skin loses its color and becomes white or lighter in color. The exact cause of vitiligo is not known, but it is believed to be an autoimmune disorder, where the body’s immune system attacks and destroys its own melanocytes.
In people with autoimmune diseases, the immune cells attack the body’s own healthy tissues by mistake. People with vitiligo may be more likely to develop other autoimmune disorders as well. Normally, the color of hair and skin is determined by melanin. Vitiligo occurs when cells that produce melanin die or stop functioning.
Topical steroids are creams or ointments that can help reduce inflammation and restore skin color. They work by suppressing the immune system and can be effective in treating non-segmental vitiligo. People with vitiligo may experience premature graying of hair on the scalp, beard, eyebrows, or eyelashes. The hair in the affected areas may turn white or gray, which can be a distressing symptom for some people. This occurs because the same cells that produce pigment in the skin also produce pigment in the hair.
