Vitamin D is imperative for building strong bones and teeth. Also, it boosts our immune system and helps fight infection. Plus, it promotes hair growth and reduces hair loss. But many of us are lacking in vitamin D. That’s because we live and work indoors or use too much sunscreen.
Vitamin D: The Sunshine Vitamin
When the sun’s rays hit our skin, it makes us warm. Our skin is the primary manufacturing site for Vitamin D. The cholesterol in the skin gets converted into pre-vitamin D3 and enters the body. But, it’s not an active form so it cannot be used. The pre-vitamin D3 has to undergo more processes in the liver and kidneys to be finally transformed into an active form of D that can be utilised by our cells.
The sun emits two types of ultraviolet rays, UVA and UVB. The skin needs UVB to make vitamin D. Out of the two, UVB is hard to catch – because of the clouds. You can’t reap sun benefits sitting indoors, either.
For vitamin D, the sun must be high up and hot. That is why people hardly make vitamin D when the sun is low in the sky. They lack UVB rays.
Vitamin D is a vital nutrient for our body, and it must be supplied. Either by spending time in the sun or by supplementing. Let’s find out what happens when you don’t have enough vitamin D in your body.
Why is Vitamin D So Important?
The bones in our body are undergoing constant repair and renewal. The function of vitamin D is to help our bodies absorb calcium from the foods we eat. Vitamin D, along with calcium, aids in mineralising and building strong, healthy bones. An early sign of vitamin D deficiency is bone pain. Also, it can cause the bones to become soft, weak and prone to breaking.
But vitamin D’s role is much more than preserving our skeletal health. Vitamin D helps to regulate our immune system.
Further, getting enough vitamin D may also protect us against several chronic conditions such as breast cancer, heart disease, multiple sclerosis, diabetes, bowel cancer etc.
Vitamin D is pretty essential for our overall health. If you don’t have enough vitamin D, its signs and symptoms are vague and subtle, it’s hard to know what’s causing them. That’s why vitamin D deficiency often goes unnoticed for a long time.
Vitamin D is also required for hair follicle growth, so if you have D deficiency, you may get hair loss and thinning. Let’s delve more into the hair topic…
Vitamin D and Hair Loss
It appears that it helps in creating new hair. If there’s not enough vitamin D in supply, and no new hair will grow to replace the old ones.
Low Vitamin D and Female Pattern Hair Loss
Female pattern hair loss (FPHL) is the thinning over the top or crown of the head. It’s one of the most common types of hair loss in women. There’s no one cause of FPHL. The role of genetics, androgens as well as nutrient deficiencies are proposed.
Vitamin D deficiency and Alopecia Areata (AA)
AA appears as a small bald patch or patches on the scalp, about the size of a coin. Since vitamin D helps in regulating the immune system, its lack can cause autoimmune conditions such as rheumatoid arthritis, thyroiditis, as well as alopecia areata.
In the case of alopecia, immune cells attack hair follicles, causing inflammation and eventually hair loss. The good news is that hair loss due to vitamin D deficiency is reversible and hair regrowth can happen.
The use of vitamin D cream on alopecia patches was investigated in 3 studies. Interestingly, hair regrowth was seen in more than 40% of the participants after 3 months of applying vitamin D cream.
However, it can be a tedious and long process for some. If you’re looking for instant results, try Kerrato hair fibres. It works like magic within seconds.
