Every morning my bathroom ritual includes checking for two things, wrinkles and thinning hair. Call me paranoid but I want to be ready at the slight sign of either one. To be honest out of the two I think I could handle wrinkles fairly easily I mean it’s nothing that a spa day with a side of botox couldn’t cure!
Thinning hair and hair loss on the other hand is a whole other ball game because to reverse it you will need to find out what is causing it.
One easily overlooked cause is vitamin D deficiency. Studies have shown that there might be a direct link to hair loss and thinning hair due to low levels of vitamin D especially among people with darker skin tones.
Why is that? Well you know the famous saying ‘black don’t crack’? They might actually be right. The melanin found in darker skin causes us to be especially prone to vitamin D deficiency because it actually blocks vitamin D* production even with exposure to the sun.
About Vitamin D
Affectionately called the sunshine vitamin, Vitamin D* is naturally produced in the body with exposure to the sun. The vitamin is fat soluble and responsible for the absorption of calcium and phosphorus which keeps the bone structure strong and intact.
Vitamin D is also key in the process of cell division which might be the reason such large amounts of it tend to be found around the hair follicle. Hanging out at the hair follicle is all well and good but does vitamin D directly increase hair growth?
The only thing that can be said with absolute confidence is that it aids in the growth process of the hair follicle and based on that, the assumption is drawn that low levels can actually cause hair loss.
