A diagnosis of telogen effluvium is established when over 20% of the hairs examined are in telogen phase. Dystrophic hairs have a decreased proximal diameter, an irregular contour, no epithelial sheaths, and an angle of over 20°. They are common in AGA or in hair that has not been removed correctly from the scalp.
hair shedding (telogen or anagen effluvium) baldness (alopecia) excess hair (hirsutism)
The condition may be triggered by things such as blow-drying, ironing the hair, over-brushing, perming, or excessive chemical use. In some cases, trichorrhexis nodosa is caused by an underlying disorder, including very rare ones, such as: Thyroid gland not making enough thyroid hormone (hypothyroidism)
Evidence is presented to support a new concept that miniaturization is an abrupt, large-step process that also can be reversed in 1 hair cycle, as has been shown clinically, with confirmatory histologic evidence, in patients with pattern hair loss responding to finasteride treatment.
Alopecia areata is a disease that happens when the immune system attacks hair follicles and causes hair loss. Hair follicles are the structures in skin that form hair. While hair can be lost from any part of the body, alopecia areata usually affects the head and face.
Severe and prolonged hypothyroidism and hyperthyroidism can cause loss of hair. The loss is diffuse and involves the entire scalp rather than discrete areas. The hair appears uniformly sparse.
Vasculitis: Vasculitis involves inflammation of blood vessels, leading to various symptoms depending on the affected organs. The diagnosis often requires imaging studies and biopsies, making it one of the more challenging autoimmune diseases to identify.
Receding at the Hairline and Temples – Hair typically recedes at the hairline for men, while women see hair receding around their temples. The hair around your hairline or temples may be shorter where the hair loss is occurring. This is called hair miniaturization.
Several different vitamins and mineral deficiencies can cause hair loss. Examples include vitamin D, vitamin B, iron, and zinc. If your hair loss is due to vitamin deficiency, supplements may help restore hair growth.
Dystrophic hairs have a decreased proximal diameter, an irregular contour, no epithelial sheaths, and an angle of over 20°. They are common in AGA or in hair that has not been removed correctly from the scalp.
Bamboo hair, which is also called trichorrhexis invaginata, is a hair-shaft abnormality. It causes your hairs to have ridges — like the ridges on a bamboo shoot — at regular intervals along each strand. The hair is also usually dry, brittle, and prone to breakage.
Menke′s syndrome and Elejalde disease are the two neurodegenerative disorders of dermatological interest. These patients present with characteristic hair changes which may be of diagnostic value in resource-poor setup where facilities for specific genetic analysis are not available.
Ans: The best vitamins for a good hair care experience are Vitamin B12, Vitamin C, Vitamin D, and Vitamin E. They should be ably supported with other nutrients and minerals like Zinc, Biotin, Iron, and Keratin for the best results.
So dead hair follicles can look like a smooth, bald patch of skin or like a scar. A trichologist may be able to get a better view of your follicles by using a microscope or other trichological tools.
When deficiency disrupts vitamin D in your scalp, the anagen (growth) phase shortens. This prematurely pushes more resting follicles into the telogen (rest) phase. Excessive shedding occurs, resulting in thinner hair. Research clearly demonstrates this link.
This simple test measures the severity of hair loss. During a pull test, a dermatologist grasps small sections of hair, about 40 strands, from different parts of the scalp and gently tugs. If six or more strands fall out, you have what's known as active hair loss.
Context: 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.
Hair follicle miniaturization is the hallmark of male pattern hair loss (MPHL), female pattern hair loss (FPHL), and alopecia areata (AA). AA has the potential for complete hair regrowth and reversal of miniaturization.
A visible scalp through your hair can be a sign that it's thinning (but not always). The factors that contribute to thinning hair (and thus a visible scalp) include stress, diet, vitamin deficiency and ageing.
Actor Ashton Kutcher's rare autoimmune condition, vasculitis, is a disorder characterized by inflammation of the blood vessels that can be life-threatening.
Some types of autoimmune vasculitis, such as rheumatoid vasculitis or ANCA-associated vasculitis, can be life-threatening. Vasculitis causes narrowing and inflammation of the blood vessels, which comprise the arteries, veins, and capillaries.
Myositis usually affects the muscles you use to move, including muscles in your: Arms and shoulders. Legs and hips.
