When it comes to hair growth, vitamin D is known to work by binding to certain receptors found in the hair follicle. These receptors help regulate their function by stimulating cellular activity, particularly in the anagen phase of the hair growth cycle. Adequate levels of vitamin D can help create new hair follicles to support healthy hair growth, while a deficiency can disrupt the hair follicle cycle and cause poor hair growth. In addition to vitamin D, vitamins B6, B12 and folic acid may also be beneficial for hair growth.
However, it is important to consult a doctor before taking any type of supplement. Unhealthy hair can manifest in a variety of ways, such as thinning hair, brittle and weak locks, dullness, and lack of growth. Signs of unhealthy hair include noticeable hair loss or thinning, lack of growth, dryness, weakness, brittleness and dullness. Dermatologists can prescribe vitamin D supplements to treat hair loss in different ways.
Diets low in calories, fat and protein can contribute to poor hair health and hair loss, known as telogen effluvium. Some forms of hair loss, such as telogen effluvium, can be caused by extreme stress or a traumatic life event. Fortified with vitamins, herbs and bioactive ingredients, certain shampoos are designed to strengthen hair and promote healthy growth. If you suspect that there is an underlying cause of your hair problems, consider talking to a health professional.
There are no clinical studies that definitively support vitamin supplements that restore hair growth and prevent further loss. A lack of vitamin D in the body could also mean that there won't be enough keratin to stimulate hair growth and control thinning and hair loss. So how quickly can vitamin D supplements work to stop hair loss? Available studies have shown that taking a vitamin D supplement for three months can reduce hair loss and stimulate hair growth starting from the follicles.If you've noticed that your hair is thinner than before, you might be looking for products or vitamin supplements to help restore it. Despite their widespread use and popularity, there is only limited scientific evidence to support the use of vitamins to increase hair growth, prevent hair loss, or treat other conditions.
