The most common type of hair loss in women is a condition called female pattern hair loss (FPHL), also known as androgenetic alopecia. Scurvy develops over at least 1 to 3 months of sustained severe vitamin C deficiency (Deirawan et al., 2020) and can be summarized by the four Hs: hemorrhagic signs, hyperkeratosis of the hair follicles, hypochondriasis, and hematologic abnormalities (anemia). The onset of scurvy is marked by systemic symptoms, such as fatigue, malaise, and To sum up, the most overlooked causes of female hair thinning can be both external and internal. For example, the external causes are stress, hair dyes, and hard water. Alternatively, the internal ones are thyroid disorder, lack of iron, biotin, and vitamin D, and excess of vitamin A. According to Toronto-based family medicine practitioner Dr. Sheila Wijayasinghe, nutritional deficiencies are one of the four main causes of nail problems like peeling or cracking. A lack of fat-soluble vitamins like vitamin D or A is a primary reason. Not only does vitamin D itself appear to play a role in maintaining nail integrity, the The next deficiency that can be linked to hair thinning and hair loss is a Vitamin D deficiency. REASON: Vitamin D plays a critical role is stimulating new and old hair follicles. As a result, when your levels are low, it can stunt new hair growth. In fact, a Vitamin D deficiency has been linked to Alopecia, an autoimmune condition that occurs Vitamin D deficiency: Vitamin D stimulates the growth of new hair follicles, therefore experts believe a deficiency can cause hair loss or thinning.

The National Institute of Health’s Office of Dietary Supplements recommends 400 to 800 IU of the vitamin per day 1. This can be obtained from foods such as fortified dairy products and cereals The role of vitamin D has been well established in AA, which is a hair follicle-specific autoimmune disease. Systematic review and analysis by Gerkowickz et al. showed the correlation between vitamin D deficiency and AA. It analyzed a total of 14 studies. Vitamin D deficiency was found to be prevalent among all the patients suffering from AA. For example, Vitamin D deficiency can lead hair follicles into a resting phase, leading to hair thinning or loss. Also, a Vitamin B7—biotin deficiency would weaken the hair shaft and lead to brittle and easily broken hair. An adequate presence of these vitamins in your daily diet can help to avert these effects.
